Sony PlayStation

[chilly kraken]

so many buttons

[clear rock]

What, did each button have it's own pin?

I thought the controller ports would have been serial by that point

DB15s??????

Yeeeah, why am I not surprised that Atari did something like this

For N64 though I find it easier to just use SNAC

Hope MiSTer can get USB analog triggers someday, NiGHTS controls glitchy without them

[dawn axle]

My understanding is that it’s probably possible, but sorg is (understandably) touchy about modifying the underlying controller related code that it would need

[stable perch]

what's that a picture of ? Jaguar ?

Or new Atari thingie

[clear rock]

That's an Atari Jaguar

[chilly kraken]

Technically the newest atari console

[opal carbon]

Well... technically the Flashback series and the 2600+ are Atari consoles yeah?

I have one of those weird Atari emulator boxes because my Dad saw one at Costco and thought I would enjoy it (I do, but because it's weird and shitty)

Actually I should see if those joysticks work with MiSTer

[desert otter]

It doesn't have the U next to it? interesting. It is the first I've heard of it interfering with a game via playback of cutscenes. Is your copy of SH redump? Can you share the save state

[summer sage]

i'd call them emulators of consoles

in the same sense that the analogue NT mini is an emulator of a console

[clear rock]

I thought the Analogue NT used the CPUs and PPUs from harvested NES consoles?

Oh wait, you said mini, nevermind

[vagrant moat]

You can use regular old hard disks with Mister?

I thought they just took sd cards

[serene nebula]

You can but I don’t recommend using a rotational because of the power draw.

[vagrant moat]

SD card seems better. Nice and compact

[mortal oracle]

SSD gang rise up

[dawn axle]

CIFS network share gang make sure your network connection has established before loading a core

[clear rock]

Punchcard gang, load up your pong cores!

[queen ore]

hi all, im trying out silent hill on the psx core and have noticed that every line of dialog (so far?) gets cut off about a second before it's meant to end. anyone know what might be going on?

(i don't see anything about this in the known issues thread on misterfpga.org, but that thread doesn't seem to have any posts since 2022 so maybe there's another resource i'm not aware of for info like this)

[digital zinc]

Make sure you're not using CD fast seek or a faster than original CD speeds, and try acquiring a different dump of the game, bad dumps can cause these kind of issues.

[queen ore]

will do, thanks

[dawn axle]

Specifically, try looking for one that’s part of a Redump collection

[worn hare]

Hi. I'm trying to tinker with psx save files. Has there been changes on psx core save file management, since im getting contradicting info on googling about it.?

should they be .sav files or .mcd?

this looks like it. Though i made a new save in SotN, but the last modified date didn't change on the corresponding .sav file

[golden ginkgo]

they are same binary wise, just two file extensions for the same file, you can just change the extension in Explorer if needed #psx-chat message

how do you store the ROMs?

[worn hare]

on a separate usb drive

[golden ginkgo]

I mean the file structure, see here: https://github.com/MiSTer-devel/PSX_MiSTer?tab=readme-ov-file#memory-card

Games that are in their own folder will create it's own memory card in media/fat/saves/psx as .sav

[worn hare]

ah, let me check. its been a while since i've touched the machine

yea they have individual folders

so otherwise they would go into a single memcard file

[golden ginkgo]

seems like, looks ok? I assume you haven't tested, just suspecting it's wrong due to last modified date

I never checked how it works with USB, would be nice if it had corresponding save paths in the USB like with rom files, but docs not mentioning (or I missed it)

[worn hare]

ah needed to reload the core to reload the saves

ok renaming did the trick, the save file just didnt update instantly after i created the save on sotn, which made some confusion

thanks

[manic citrus]

saves are only written when the OSD is opened

so if the game saves, you need to open the mister menu to commit the save to disk

[bitter lintel]

how do you save your sanity?

[somber steppe]

On a memory card, obviously.

[clear rock]

I deleted that long ago

[scenic rain]

https://youtu.be/IzPunGJay8g?si=2928UpwLVuBJ5uS4

[mortal oracle]

Looks awesome! 😄

[scenic rain]

Multi Minivan Drifting

[bitter lintel]

that's a poor man's rage racer

[stuck smelt]

I think I’ve found a game which doesn’t look correct on the core

Vanark

In the weapons menu

Flickers like hell

[hallow quartz]

It's correct, that part is 480i so won't look as stable as a progressive image.

[stuck smelt]

Does it flicker this crazy on og hardware?

[chilly kraken]

probably not if you're hooked up to a CRT

i can look at it when I get home

[somber steppe]

I should test it on the rt4k, that one is usually pretty good at cleaning up 480i.

[dark mountain]

Bob/Weave desinterlacing could help ?

[stuck smelt]

I’m playing on a CRT

It flickers not the usual 480i style of flicker

[digital zinc]

doesn't seem to be present over HDMI, weapons menu is perfectly stable

[stuck smelt]

Ok I think I found the issue

I had turned on 480i to 480p in the settings

:/

[tawny palm]

MiSTer wins again!

[desert otter]

Lol, so user error. Were you previously using HDMI and forgot?

[stuck smelt]

No I’m only using CRT. I must have edited the settings and forgot to change back

[ember depot]

Does Symphony of the Night still benefit from Turbo speeds? Trying to find settings that reduce the down time between opening and closing the Inventory.

[proven seal]

i don't think anything is going to improve the load times between opening and closing the menu. you can set turbo to high to remove some slowdown, but that's it. increasing cd speed too high breaks the game during load rooms and dialogue, in my experience

are you playing on a crt? the game changes resolutions when switching between gameplay and menus, i know some scalers and tvs briefly drop the signal when that happens

[clear rock]

The menu needs to load? Sure it's not just resolution switching that's the downtime?

[rapid garden]

playing Silent Hill on the mister and i had no idea how much color banding dithering was hiding lmao

[clear rock]

I turned off the dithering

[rapid garden]

same, the character models look really good without it

worth dealing with the weird color banding imo

[dawn axle]

PS1 without the dithering is like N64 without the texture filtering

[serene nebula]

You can boost the colorbit to remove the color banding

But yeah, adding dithering on hardware to save perf on color resolution was amazingly brilliant

[mortal oracle]

Fake fan

[empty yacht]

well, it is robby

[proven seal]

the menu takes a solid second or so to pop up in most cases

[worldly hound]

Hi, I am having some weird visual glitches with Spongebob Squarepants SuperSponge, any potentially cause and or solution for this?

this happens at the very start of the game after the menus which look fine normally

[chilly kraken]

Of course it's under "Nickelodeon's"

https://github.com/MiSTer-devel/PSX_MiSTer/issues/310

[tacit fox]

Is there at least an explanation for that issue? Is the PSX core not being maintained anymore?

[manic citrus]

I mean, Robert is a bit busy 😉

[frail storm]

Out of curiosity, I have found that in DuckStation (current) and in Mednafen, Tekken 1 (USA/JP) shows a strange bug: stage music first second sometimes repeats, then continues normally.
The game uses CDDA tracks and I don't see any other games using CDDA being affected.

However, that does NOT happen on the MiSTer PSX core! 😮

Who's right? Is this a known bug of the game itself, or is the core better in handling CDDA tracks than the most refined PSX emulators known to man?
It's specially strange since DuckStation was used as the reference for behavior comparison when the PSX core was being developed...

[mortal oracle]

I suspect there are areas where duckstation is more accurate and other areas where MiSTer is more accurate

But I don’t think it’s accurate to say Duckstation was the reference, but instead a reference when it came to checking specific features (thinking about the differently coloured blocks in the resident evil games, for example)

the reference was probably original hardware and then Robert’s own software emulator

[serene nebula]

I just say MiSTer is more accurate and don’t think about it

[mortal oracle]

That’s basically why I’m here. No more thinking about what emulator, whether a dropped frame was my computer being weird, whether I misconfigured something etc 😅

https://tenor.com/view/play-the-game-reggie-nintendo-gif-22934152

[serene nebula]

In all seriousness, yeah 100% agreed. It’s an emulator; it emulates a known quantity. I just want it to work with zero configuration, zero setup should be required.

[tropic stratus]

Very strange that sponge bob has two bugs at the same time. Wouldn't be surprised if it's the same cause, even with them being so different.

[tropic stratus]

added some quick analysis in the github issue. No easy fix I fear. But at least it's documented what happens.

[tacit fox]

Core has reached a dead end on the MiSTer it seems. Modretro FPGA PSX wen

[timber flint]

I'm shocked Analogue never made a PS1

[tacit fox]

Doubt they ever will. They can’t even deliver a promised N64!

[timber flint]

Ah it'll come at some point. Like all their products though it'll take forever

[serene nebula]

I think it’s due to how complex cdrom emulation is? They only focus on cart-based consoles.

🤷‍♂️

[timber flint]

The duo seems to read CDs well. I hope they do another Genesis that plays Sega CD discs too

[somber steppe]

If only we had an fpga platform that did all of these things and wasn't tied to some shady company...

[ember depot]

Possibly the downtime between resolution switches even with the sync 480i. I'm also using BT and not Snac.

Agent Armstrong does some funky stuff with resolution switching during explosions and similarly locks the game up aggressively.

[serene nebula]

oh duh, I fogot about that thing lol

[timber flint]

Everyone forgot about that thing to be fair 😂

[mortal oracle]

Including Analogue if the updates are anything to go by

[tacit fox]

🤭

[timber flint]

I've never had any issues with mine on the latest firmware but I've only played like 20 games on it so far

[mortal oracle]

I’m never had any issues on my MiSTer either

[timber flint]

I enjoy collecting all the various retro pieces of hardware and go back n forth between them all. I have problems and I fully acknowledge it

[mortal oracle]

If it gives you pleasure, I see no harm in it

It’s not like there’s a problem with a person owning more than one FGPA device, is there?

[timber flint]

Most days I use the mister, some days I go real hardware, or an analogue machine. No rhyme or reason to my madness

One can never have to many fpga devices

[mortal oracle]

Using the MiSTer for me means I can massively simply my setup. All my original hardware and games are in storage, and I need fewer things connected to my TV

[timber flint]

I haven't even had a chance to play a game in 2 1/2 months now. Haven't even turned a console on 😭

My dad passed away at the beginning of August and I've been so busy handling the estate, grieving, moving into his house and fixing it up

[mortal oracle]

I can relate. Sorry for your loss. Take care of yourself 😔

[timber flint]

I'm hoping by Thanksgiving my life will be boring again and I can game again.

My dad was a huge DOS gamer back in the day, so my brother and I made a list of all his favorite DOS games and we're gonna play thru them this winter

[mortal oracle]

I did the same thing with some we used to play together when I was a kid 🙂

[ivory verge]

The music loop in the last track should now work fine.

[spark ermine]

Is there a list of games to see the effects of the old gpu? Only one I can think of besides tomb raider is spyro the dragon

[desert otter]

does using old GPU option fix the graphics in SpongeBob?

[abstract drift]

probably not, i dontt tihnk it actually affects timings at all

[serene nebula]

Ok genuine question but why people playing SpongeBob PS1

Is it a fun game or is it a big nostalgia thing?

[mortal oracle]

Wasn’t one of the SpongeBob games actually good? Maybe that was a PS2 one though

[serene nebula]

Yeah Battle for Bikini Bottom was neat, first one I heard being good

[mortal oracle]

Thank you

[tribal sorrel]

I tested CHD images of Wipeout 2097 and Wipeout 3 SE, both PAL, as they also had this issue. The last music tracks now loop correctly.

[ivory verge]

https://youtu.be/IEJd69tYzn8?si=FKm4ujPMi0oR1kNT

https://youtu.be/zPQr7mVThoU?si=pd7M9tC59nBWFtJT

[desert otter]

new gpu looks a little brighter too which I think looks better especially with how dark a lot of games were back then. helps keep some details from getting too crushed

[glossy geyser]

Yep it works. I tested all 3 games. What was the problem out of curiosity?

[ivory verge]

playback command. In short, Wipeout sends a Play command without parameters during playback, it did not play correctly in a loop because the core did not correctly recognize the “Play” command sent by the game after the audio track ended.

[tribal sorrel]

Thanks for that - I'll test a few more cd-da games today

[glossy geyser]

Huh... so the game just says play without a track number?

If that's the case I better make sure the last track shuffles as well as repeats

[glossy geyser]

All is well, it shuffles off of the last track to.

[bright yacht]

There's now the option to choose PSX old or new GPU? That's amazing! I was talking about that with a friend the other day, that would be great to have this option on mister

[tropic stratus]

Thank you so much for researching the root cause!

And fixing of course as well, but I think the research probably took more time 🙂

[glossy geyser]

This is the first I've ever heard of a meaningful GPU revision on the PSX. You learn something new every day.

[glossy geyser]

Apologies for the ping on a semi-related question but I couldn't make sense of HDL languages if my life depended on it, never mind a project as big as the PSX core.

How difficult or trivial would it be to connect the PSX back serial port to /dev/ttyS1 on the Linux side like the AO486 core does with COM1? I ask since I'm in the middle of writing some software to tunnel serial connections over Ethernet between two MiSTers that way.

[ivory verge]

I'm sorry, but I don't know, I've never looked into this topic.

[glossy geyser]

No problem. I'll look into it more closely when the Linux application side of things is complete

[tropic stratus]

The serial handling itself is currently not implemented. But the big issue here would be latency. It's a real time interface and I have no idea how games react if the message is coming in random time frames.

(Assuming you cannot fulfill the original low latency with linux+ethernet)

[clear rock]

This reminds me. Did the PSX have some sort of internal console? I hear that many games still wrote debug messages to this console even though it's not present on retail hardware? Or is that all nonsense?

[desert otter]

Maybe was something built into the net yaroze

[restive plover]

it has a serial console, you can break it out to a pc, even usb with converter

ps2 also has one you can expose

[ivory verge]

Pausing and resuming audio tracks in the CD player has never worked properly in core?

[abstract drift]

really?

i feel like people would of noticed that

dont some games use pause/resume extensively too?

[ivory verge]

Try playing a song, pause it, and press play.

[abstract drift]

i'm not near my mister at the mo

do you need a pure audio cd or can you use a game?

[ivory verge]

use a game

[manic citrus]

yeah, it resets to the first audio track when you unpause

I'm not sure if I ever did cd audio a long time ago, so I'm unsure if it was always like that or not

seems like something somewhere isn't holding the current sector/msf value when pause is activated?

[ivory verge]

It should be fine now. I have to go to bed, good night.

[serene nebula]

Well that was quick lol

[spark ermine]

Seems fine to me. Tested with tomb raider

Don't think i've touched the cd player portion of a playstation since I was six years old and that ui brings me back lol

Since we're looking at bugs on the core. This collectible is not supposed to look like this in Ape Escape. Don't think anyone else ever reported it

https://youtu.be/IpQ9KNhdMIY?t=4342

time stamped video. Should be solid yellow

[tropic stratus]

Thank you for looking into all this. Once you know where to look it obvious. E.g. that the play without parameters isn't covered properly at all.
Would be great if you can do a pull request so these things are not lost.

[manic citrus]

now I question what those people ripping audio cds were doing

but new ps1 homebrew demo to try

I feel like this is kind of full circle because the original version of Yume Nikki was inspired quite a bit by LSD Dream Emulator

For the uninitiated, Yume Nikki was originally a 2000s surrealist "horror" indie game where the main objective is just to explore and discover random events, kind of like an early "walking simulator", this is a remake in 3D for the PSX

[ivory verge]

please share savestate if you can, thanks!

[spark ermine]

Ok i'll send it off when I'm home

[ivory verge]

which core version are you using?

[spark ermine]

I was testing on your latest cd player one but this bug has been there for as long as I can remember

[ivory verge]

ok thanks!

When you pause the game, a yellow triangle rotates, so I think it's the same effect. It's strange that it doesn't work properly in the place you showed.

[spark ermine]

Yea that's the same thing, it was like that everywhere. I wanna say the spectre coins have the same issue too but i'd have to check

This thing

[hallow quartz]

The footage of the core also shows 3 horizontal lines of pixels on this part of the HUD which I cannot see on the play-through footage.

[spark ermine]

If no one else is seeing it, maybe it's my dump 🤔 i'll have to confirm when I'm home

[ivory verge]

Looks fine for me

[spark ermine]

Yea i'm starting to think maybe my dump is bad 😅

[hallow quartz]

These purple pixels on your footage look off too.

[dark mountain]

Fine for me too on my screens.

[spark ermine]

Gotta be a bad dump then, classic

Mister wins again

[hallow quartz]

Ditto, all good here too.

[north mesa]

feels like it's oddly specific for a bad dump, no?

[spark ermine]

Only difference would be is that my footage is from a mister pi but I recall it happening on the real de10 nano too. I'm sure it's the dump but i'll confirm it on both later anyways

[proven seal]

did you have any of the enhancements turn on? turbo, 24-bit, etc.

[spark ermine]

There's a possibility, i'll confirm when I get home in an hour or so

[serene nebula]

Could be rando visual corruption m

[spark ermine]

Well I figured out it's something with my save state for whatever reason

[scarlet knot]

What's the difference between the stable PSX core and the shifted core? I have PSX_shift240 but I can't seem to find what the differences are.

[golden ginkgo]

Is that one that came with the mister pi sd card?

Correct me if wrong, I think it is an old build without an issue of popping sounds in the core (unlike the main release at the time?) but the most recent release doesn’t have it either

[scarlet knot]

Gotcha...

I believe it did come with the mister pi card, but I don't remember for sure

[serene nebula]

It did, no one else is distributing that

Those were created because of hardware inconsistencies from the MiSTer Pi clone board and the original de10-nano but that’s been long since addressed

[glossy geyser]

Yeah, I have no idea how a PS1s serial connection would react to unexpected delay/jitter or more accurately how each PSX game would react. In theory you need only be as fast as when the CPU next makes a read request to the serial port. If it where tied to the games framerate and the maximum framerate a PS1 game should target is 60fps in NTSC regions that would make the most unforgiving titles require a total data transfer time under 16.6 ms.

I've been testing the program on AO486 with games that support null modem multiplayer. Command and Conquer, Doom, Descent, Indycar Racing & Warcraft where all perfectly playable.

Indycar Racing helpfully displays a transmission delay of 0.13 seconds upon connection and always runs at 9600 baud. This could be a good way to compare against real hardware but I don't have a computer of that vintage myself, never mind two connected with a null modem cable.

[granite oyster]

Anybody know about these visual artifacts in the bottom left?

I figured they were an overscan thing but I can't seem to reproduce it with ares even with this option enabled

the rom is Athena - Awakening from the Ordinary Life (Japan) (Disc 1)

[ivory verge]

Fixed Hblank as well as Fixed Vblank can help delivering correct aspect rations and keeping the screen in sync with e.g. shaking animations. Both also offer crop options for games that depend on CRT viewports to hide artifacts at the edge of the image.

Try these options in core

[granite oyster]

hblank/vblank does not seem to fix it. I could just crop it or go into the alignment settings on my bvm, I was just curious if it was an issue with the core

The horizontal crop option also does not seem to affect it

[ivory verge]

maybe the crop is not enough in this case

[manic citrus]

I'm not sure the noise is fully outside the visible area, actually

[granite oyster]

Nah it's not

[abstract drift]

are we sure it doesnt happen on real hardware

half the time they do

[granite oyster]

I don't have the hardware to check. I only tried it on ares

[serene nebula]

Understandable, hopefully someone here with an ODE can cross check.

[scarlet knot]

Thank you for clearing that up

[serene nebula]

The same issues cropped up with Saturn but were also quickly addressed btw.

It’s the nature of homebrew development and pushing hardware to the absolute limit. Even the most insignificant voltage difference can cause a problem at that level.

It’s frankly astonishing the level of commitment both FPGAzumspass and srg320 have for the community. Incredible work by both of them to fix that so that everyone can enjoy the cores without issue.

(and the amazing community who catches those issues and helps debug them)

[scarlet knot]

Agreed!

[burnt gorge]

Hi there I got a GCON-45 but some games like crypt killer doesn't work is there a way in Mister to force all light gun games to be able to use SNAC GCON-45 ?

[digital zinc]

For SNAC, the game software itself must support the hardware on the core it's being used on, as the mister software isn't really involved. A quick search shows Crypt Killer doesn't support the guncon, and there is absolutely no way to get mister to change that for SNAC controllers, but there may be patches for the game itself to add support for it.

[lilac scaffold]

https://forums.pcsx2.net/Thread-Nuvee-PS1-PS2-input-plugin-supporting-lightguns-by-Shalma
Theres a patch for most of the justifer games to make them work with guncon

including crypt killer 🙂

I may have found an archive where they were pre patched when I got them

[serene nebula]

[manic citrus]

plz PR that sys_top change to Template repo

otherwise every sys update will overwrite it

it's already fixed in that repo

[serene nebula]

Turbo core wen

[dawn axle]

Slow core when?

[hybrid raven]

What does the "old gpu option" do exactly?

[serene nebula]

Oh my bad, I meant 2XCPU core lol

[serene nebula]

makes it look like shit

I mean more accurate to older hardware

[cosmic tulip]

Kinda want that myself as well lol

[ivory verge]

Simulates old GPU version (CXD8514Q). Old GPU crops 8:8:8 bit gouraud shading color to 5:5:5 bit before multiplying it with the texture color. #1046940919607345272 message , https://www.tombraiderforums.com/showthread.php?t=222685It's It's just an option, but for some people it's an interesting option to see how it looked on early Playstation models.

[cosmic tulip]

Also what is dual sram mode

[serene nebula]

looks like less bit depth

[dawn axle]

1/2XCPU core when?

[dawn axle]

For setups that have dual SDRAM sticks. For PSX at this point in time it apparently makes sound playback imperceptibly more accurate

[cosmic tulip]

I thought dual ram was it's own core

[dawn axle]

I think it still is, looking at some docs there’s an option for for the sound processor to use dual sdram and that’s probably what it’s talking about

[clear rock]

Championship core when?

[dawn axle]

https://mister-devel.github.io/MkDocs_MiSTer/cores/highlights/psx/#spu-ram-select

[ivory verge]

yeah 🙂

[fluid raft]

Is a new dual-RAM build on the way?

[ivory verge]

yeah

[fluid raft]

Cool! Thanks!!!

[serene nebula]

@deft sphinx for da gyethubbo

[deft sphinx]

We don't have a dual ram DB but we probably should really, enough people want these. Do PSX dual ram get picked up by unstable nightlies?

[serene nebula]

Ohhh I was thinking of the 2XCPU core that’s up there

[manic citrus]

the only dual ram core in unstable is saturn. it has no way to know it is possible to build alternate cores so probably needs special setup

[stark tinsel]

Hi all. Quick question:
I converted my bins and cues to CHDs today, and didn't realize that all my existing save files would be invalidated

Is there any fix for me here?

[manic citrus]

they shouldn't be

[stark tinsel]

huh

[manic citrus]

save files are based on the containing folder name

you didn't move all the chds into /media/fat/games/PSX, did you?

[stark tinsel]

all the games were in their own folders containing the bins and cue

but they all moved up into the /PSX/ directory

I always figured it was based on game filename, and other than the extension those didnt change

so for more detail, my bins and cues were in, for example
/media/usb0/games/psx/Ape Escape (USA)/Ape Escape (USA).cue

and now they're at
/media/usb0/games/psx/Ape Escape (USA).chd

I'll try tossing one of the CHDs in a same-named folder

yep, that did it

Well, that'll do it I guess, unless there's a way to fix the save files so that they all point one directory up?

[manic citrus]

when you put all the chds in the 'psx' directory, it makes all of them share a memcard save file. the directories make it create a memcard per game. you should also put multi-disc games in the same folder. so psx/GameName/Gamename1.chd Gamename2.chd etc

[stark tinsel]

Ahhh

Okay that all makes sense now

Thank you!

and just to confirm before I script out all these mkdirs and moves, there's no way to edit the old saves to merge them all and point them at /psx/ ?

[manic citrus]

maybe, but you'd have to go looking for psx memcard programs, or sit there and mount each of them individually as memcard 2 and copy it over

but memcards have a size limit, so you can't just hope your entire game collection will fit, unless you only play a few games

also with all the chds in that directory, you will have to manually reset the core anytime you change games

[stark tinsel]

man

I went and made a whole slew of problems for myself!

thank you again for your help

[ivory verge]

I recently set myself the goal of finally seeing the boss at the end of the first level in Captain Commando game 🙂 This is one of the oldest bugs reported on GitHub. https://github.com/MiSTer-devel/PSX_MiSTer/issues/66

holy shit the madman actually did it

big congrats, this is sick

[dark mountain]

Oh, shit.

Very well done, kuba-j.

[abstract drift]

thats crazy well done!

how did you do it? i remember robert thinking it would take a major refactor of the cd block

[dark mountain]

No regression found so far.

[ivory verge]

The game requires a 2-sector skew between SUBQ (subchannel) information and data headers for proper timing of boss graphics loading during XA audio streaming. I used the information provided in the bug report on GitHub and the solution for software emulators.

[dark mountain]

I remember that we searched with multiple people on that issue quite some weeks with Stenzek at the time.
Only the last commit remains though, and I hope it has helped to fix the main issue in the core.

[ivory verge]

Please test more games. If everything is ok, I will submit a PR.

Unfortunately, I have limited time today

core has a good timings

and all changes mades before

thanks!

[proven seal]

reading the comments in the duckstation commit is pretty funny. looks like whoever was in charge of porting captain commando to playstation used some pretty weird tricks to load the boss graphic data

[cosmic tulip]

hey are there plans for bringing these changes to the 2xCPU core?

[odd glen]

Out of curiosity what are your use cases for the 2x core??? Are there certain games that benefit from the extra speed???

[scenic ledge]

I guess that you can google for some reddit threads with some recommendations. Mostly classic 3D stuff with better frame rate

[cosmic tulip]

Yes. A couple But also so I can do stuff like widescreen, texture filtering stuff like that in silent hill and dino crisis 1 without causing slight dips in framerate

[odd glen]

Ok cool, I’ll have to check that out. I’ve tested the 2X core but never found anything compelling enough over the stock core. Thanks for the recommendation

[burnt gorge]

Thank you sir you're awesome !

[lusty coral]

There's many games that I have tried that really benefit from the 2xcore, which allow for a smooth framerate

My default PSX core is the 2xcore.

[frail storm]

And what about the games that are negatively affected? 😄

[lusty coral]

I've yet to come across one

The only issue I have come across is that some games have issues saving if the turbo mode is enabled. But just disable turbo, save and then re enable turbo and your good to go

[desert otter]

There are no games that are negatively affected though

Because the turbo is only activated manually. It's just that the high mode is 2x instead of a lower value like the normal core.

[clear rock]

Yeah, thats the default behavior of the batch files I usually see included with chdman, usually those come with an older version of chdman as well and don't have the recommended optimization settings

If you want, I had made a modified batch file that applies those optimizations and puts them all back in the folder the bin/cue were from.

Although it does also delete the bin/cue file so you'll need to copy those somewhere if you also wanted to keep the originals

[stark tinsel]

Yeah I specifically put the CHDs in their own folder not realizing what was about to befall me 😂

But it was pretty quick to put a script together to move them back

I'd be interested in seeing what those settings are, sure

[clear rock]

If it's just the settings you want I am pretty sure they are in the pinned messages, let me check... for some reason they are loading slowly for me

Yeah, it's "-c cdzs,cdfl -hs 9792", note you will need a recent version of chdman (it's included with mame) to use these, it was added recently

Also note that this will result in slightly larger CHD files, but they will be better optimized for if you wanted to use options to speed up the disk drive faster than it normally would read the disk on real hardware

[burnt gorge]

Does anyone know why ghoul panic Europe stucks in GUNCON calibration screen even though I'm pressing the trigger to calibrate ?

[desert otter]

Is it a first Gen guncon connected with PS1 snac adapter?

[burnt gorge]

Yes it is , my crt is ntsc game is European is that a problem ? I'm forcing the sync with the pal 60 option in Mister

[desert otter]

And you're using the composite connector adapter thing too right?

[burnt gorge]

I don't have any problems with other games

[desert otter]

Ok then my guess would be it's a pal to ntsc thing

The game is expecting things to sync up at 50hz and you aren't running 50hz

[burnt gorge]

Is there a patch or something to fix that ? 😭

OK so even in the Japanese version same thing happens I can pass that screen after aiming and pulling the trigger

Like I said before I'm using SNAC and this is the only game at least at the moment in which I can't pass the aiming screen

👀

OK so something is really odd here the only game which I have this issue

[tropic stratus]

interesting. I tried a simple delay of the subchannel data by 1 or 2 sectors in my software emulator and it didn't work, so I never tried the FPGA implementation. Was it that in the end or more?

In any case, great work on the core!

[burnt gorge]

As you all can see it works only if I pull the trigger at the side of the TV but whenever I want to aim at the center it instantly dissappear

[frail storm]

Is there a dualRAM build including the Captain Commando fix?
Or is the vanilla build now dualRAM capable via the SPU RAM option? I am a bit lost with regards to that

[serene nebula]

There is no dual ram build with the captain commando fix

[frail storm]

Ah, thanks!
So, the SPU RAM option is only available on the dualRAM builds then?

[serene nebula]

Yes but you’re aware that it has no human perceivable effect, right?

[ivory verge]

with Commando fix

(if needed)

[hallow quartz]

And if I remember correctly Robert said the dual ram core also speeds up the emulated GPU as it is no longer as bottle necked, making that less accurate.

[frail storm]

Thanks! 🙂

[frail storm]

Hmmm.. shouldn't it be more accurate? DDR3 is shared with the OS, while secondary SDRAM is not

[hallow quartz]

#1046940919607345272 message

[frail storm]

Oh, I see... interesting stuff.
Has Robert also explained why didn't he do an (optional) version with video RAM on secondary SDRam? That way, the GPU and the OS wouldn't have to fight over memory access, since OS runs on DDR3

[serene nebula]

Ok yeah I forgot, I’ll remove the dual ram link then.

It’s less accurate

[serene nebula]

Thanks dude

[hallow quartz]

My guess is that he chose to spend the development time doing the best as he could with single ram as that is what the vast majority of users have instead of splitting things like that. I think the dual build only exists because it was necessary or helpful early in development.

[serene nebula]

Single ram is always the priority and focus, dual ram just exists to help devs early on in development before optimization. The only outlier is the Saturn core and srg320 has worked like hell to get it as perfect as possible on single ram.

but dual ram is cool, I have it lol

[chilly kraken]

Jaguar core too

[clear rock]

I wonder if that fixes the Chrono Cross bug

[opal carbon]

My understanding is the GPU timing is too fast with Cross on single RAM.

[hallow quartz]

The GPU needs to be ran slower like real hardware for that stuff to be resolved, dual ram makes it even faster so won't help.

[opal carbon]

Yeah this is why loading the GPU with some of the optional features fixes Cross.

[clear rock]

I thought that the turbo core still helped with that?

[rose ermine]

I know it's been said before, but I like to put into numbers the lack of perceivable effect on audio with the dual RAM core - Firstly, it's not a constant delay, it only occurs when the audio buffer is full. When the audio buffer is full it's a delay of one extra cycle of RAM. IIRC that's 100 nanoseconds or 0.0001ms. Sound travels 0.034mm in 100 nanoseconds. Swapping from over ear headphones to in ear earbuds would reduce latency orders of magnitude more. Doing the gamer lean and getting closer to your speakers would reduce latency by orders of magnitude more.

If we're talking latency in terms of a frame, 100 nanoseconds is 0.0006% of a frame. That means if you are purely reacting to the audio to cue your frame perfect input, the delay will cause your input to miss the exact frame approximately 1 out of every 166,667 frames and again, that's only when the audio buffer is full.

[serene nebula]

if the human computer says its no good, u better respekt. case closed

[hallow quartz]

The DE-10's DDR3 latency is the reason for having to run the GPU faster, a turbo core can't help get around that particular hardware limitation unfortunately.

[hybrid raven]

The dual ram core is not the most accurate now? I haven’t been following core changes too closely and thought dual was still best.

[hallow quartz]

I'm not going to tell anyone what to use but having read Robert's post I will take a more accurate gpu over an audio improvement so slight that I will never ever notice.

[manic citrus]

the best use of the dual sdram psx core is verifying your dual ram is installed

[clear rock]

https://tenor.com/view/dumb-and-dumber-lloyd-theres-a-chance-jim-carrey-gif-11098164

[clear rock]

Nah, there's a dual Ram version of that Ram speed test score

XD

[tropic stratus]

Dual sdram is more accurate sound timing, but less accurate GPU timing, due to there being less sharing the DDR3 and it's too fast anyway.
There is a "Slow GPU" option, but it's more of a hack, as accurate timing isn't possible with random DDR3 latency.
Using Dual sdram for GPU would certainly be a possibility for more accurate GPU, yes.
In never did this, because of the low count of users and the amount of work required. This might be different for future hardware.

[frail storm]

Thanks for your input on this 🙂
Well, now that dual sdram is more common (I believe Saturn might need it in the end for some of the important games on the system unless a hacky option is used that breaks other games), maybe it would make sense to have a more accurate GPU on the PSX core with optional dual sdram... but of course that's up to you!

[chilly kraken]

The “Single Ram is the Goal” people are coming

[frail storm]

I'd also prefer single RAM all day long, sure, but if dual RAM is the only way to have accurate enough GPU so games don't glitch, then...

[serene nebula]

Single ram is the goal

shit

I fell for it!!!

[serene nebula]

CRT users don’t have dual ram and we don’t want to prevent a large number of users from being able to enjoy a core

[serene nebula]

Saturn’s use case for dual ram is making VF2 engine based behave more accurately to the original speed, which is just a handful of titles. And even then there’s a fast timings option for single ram. Dual ram is definitely not needed.

It also helps fix a glitch in Grandia for some users who have single sdram but others with single sdram also don’t have that that issue. Honestly, the Saturn is such a complex beast, ram isn’t the bottleneck here.

[chilly kraken]

I have dual ram connected to a crt 🥹

[serene nebula]

Using gross adapters no less!

[chilly kraken]

Sir I have a io direct. Lovingly crafted by our friend porkchop

(In Idaho)

[somber steppe]

Did you know Robby is friends with him personally? He mentions it every chance.

[serene nebula]

Oh ok so now we have to ask CRT users to buy a new IO board and another stick of ram? Nah, that’s not cool.

It’s part and parcel of homebrew development I know, but if we can optimize that’s always better than telling the community “spend more money”.

It’s been what, like 8 years of MiSTer and the only use-case for dual sdram is just one core to help improve timings for a small handful of games and even then single sdram has an option to mitigate that discrepancy. Jaguar core benefits from dual sdram too but that’s still in development and not done.

[somber steppe]

Dual ram is only for real men, single ram is for real ||fat|| babies.

[serene nebula]

[somber steppe]

I don't think people should spend more money on mister. I think people should spend ALL their money on mister!

[dense wharf]

people who pay more game more

[frail storm]

What would CRT users lose if there was an OPTIONAL dualRAM PSX core with more accurate GPU? 😮

[serene nebula]

Because we now have two class of MiSTer users and that doesn’t sit right with me, IMO.

Ok I’ll stop arguing. I don’t want to make anyone feel like I’m stepping on their toes or preventing them from having what they want,

I want people to be happy with MiSTer that’s all

sorry

[dawn axle]

Are the supposed inaccuracies in the current GPU code enough for anyone to actually notice?

[somber steppe]

Tow class societys are inherently better as long as you're on top.

[somber steppe]

Human, no? Robot? Yes!

[dense wharf]

class societies are good because im on top

[dawn axle]

well shit we need to get on that then, we can’t let our robot overlords have a sub-par mister experience!!

[serene nebula]

If the core developer wants to do dual ram to get the absolute most, who am I or we to say “no thank you”

[somber steppe]

I never was so I'd be excited to be a dual ram 1%er.

[somber steppe]

Beep boop.

[serene nebula]

Optional is great, you’re right

[dawn axle]

Oh, well, if you’re the only robot overlord here then maybe it’s fine as is

[proven seal]

i'm a crt user so it would be a hassle switching my existing setup to dual ram

i'd rather wait for a potential "mister 2" to come out and see improvements on the psx core there

[serene nebula]

my arguments are pretty pointless considering what you just said. We’re likely a year or two away from a successor hardware. So I don’t know why I’m so passionate about sticking to single sdram.

[somber steppe]

Not sure how desirable a successor will be to most users. What would it do that mister can't do now? Some weird arcade boards and maybe dreamcast.

[serene nebula]

yeah also very true

I think we’ll see improvements to Saturn/PSX/N64/ao486 for sure.

[somber steppe]

I think the real takeaway is that tubemen are a relic of the past and scaler boys will rule the earth!

[serene nebula]

The irony behind my arguments for single sdram is that I have a scaler and dual ram lol.

[proven seal]

whatever board winds up being used in the next iteration of the mister project, dreamcast won't be happening. if we do get new hardware, it'll probably be closer to a mister 1.5. personally, i would be all in on it; more headroom for existing cores and more space for newer arcade cores would be enough for me to switch

[somber steppe]

Those consoles are functionally perfect imo. Why spend a triple digit amount to play the same games?

[serene nebula]

Very true

[proven seal]

i disagree. as good as the 5th gen cores are, there's a lot of room for improvement in all three

[somber steppe]

Meaningful improvement though? I don't use any turbo core and appreciate the simplicity and compatibility.

Savestates are nice for consoles that didn't support battery saves but I don't use them on other cores.

[proven seal]

absolutely. lots of ps1 games still throw up E2 errors often and there's the matter of the gpu issue in chrono cross, many saturn games don't run fast enough without the inaccurate "fast timings" option enabled, and n64 lacks rtc/64dd support, and some games run too fast while others are too slow

[serene nebula]

I am part of the “works well enough” camp lol

[abstract drift]

E2 errors dont actually mean the core did anything wrong neccesarily

[serene nebula]

So I love people who have crazy attention to detail

[abstract drift]

some games throw (and catch) e2 errors naturally

[dawn axle]

Scaler boys of the world unite

[proven seal]

that's true, thank you for pointing it out. i've not seen any games encounter an unrecoverable E2 error, but it happens regardless

[abstract drift]

you can just disable the debug overlay its really only meant for development

[proven seal]

i do understand and largely agree with that philosophy, though i feel that the mission statement of the mister project is to get as close to the original hardware as possible. some corners had to understandably be cut for ps1, sat and n64 to fit on the cyclone v, but i would love a "no compromises" option in the form of a bigger fpga

[serene nebula]

It absolutely is and we should always strive for that. I just can’t hang in that rodeo because I’ll be sitting with an incomplete core and going “this is fine!” lol

[proven seal]

that's very fair. i'm sure plenty of people are in both camps

[abstract drift]

in practical terms your only going to get like a handful of games that run a bit more accurately

i'm still all for it but i can understand if some people just stick with their de10nano

[proven seal]

yeah, absolutely

[serene nebula]

Of course I’ll be upgrading the moment Sorg gives his blessing so again, hypocrite here

[proven seal]

perhaps the de-10 nano could become the "standard" board for building a mister (as it already is), and the de-25 nano a "deluxe" board for people who really want to get the most out of the mister project, like with the examples discussed here. the future is still uncertain in regards to the latter though

[abstract drift]

only makes sense if the de25 is significantly more expensive

which i dont think it is? especially when you consider you probably dont need a ram module

[proven seal]

well if that's the case then i'm all for that too lol

[abstract drift]

though hopefully the de10nano does remain like, somewhat fully supported

backporting fixes etc, there's still plenty more it can do

[frail storm]

As a communist, neither do I 🙂
But from the preservation perspective, I think a more accurate GPU is desirable. And the single RAM user wouldn't lose anything: if it was the case, I would be against it, of course!

[serene nebula]

Yeah, ignore me. I don’t know why I get passionate about this. Sorry.

[frail storm]

No need to be sorry at all, Robby, it was an opinion. We can have different opinions on most topics.

[dense wharf]

pentium mister....

[dawn axle]

Robby you’re a mod, that means your opinions are objectively correct and absolute

[serene nebula]

LOL quite the opposite

[dense wharf]

whats the point of being a discord mod if you cant force your opinions on the proles?!?

[dawn axle]

It’s so that he can have his face as an emoji

[serene nebula]

lol why am I pooping

[frail storm]

Not eveybody has his own emoji! 😄

[serene nebula]

well, you’re right @frail storm , I just need to keep in mind that optional is the key word here.

And it’s a great point too, accuracy is the goal

and @chilly kraken is right too, new IO boards have solved the CRT issue

[frail storm]

For example, I love Time Gal, and it doesn't look quite well on the MiSTer due to the imperfect GPU, which is a pity. No matter what option you set, the game never ever looks good 🙁

[serene nebula]

Aw that sucks, on the PSX core? What’s the problem?

Time Gal is also amazing

[frail storm]

Flickering on the upper part of the screen. Very distracting for an FMV game.

Sometimes it takes an scene of two to start happening clearly.

I already commented it on the "games that need accurate GPU timings" on github

[chilly kraken]

I do think that single ram is the defacto “standard” mister, and i think that is ok. Gen 5 consoles are a miracle on the de10 anyway. On the next board, there will be a new defacto standard.

[serene nebula]

That’s a great way of putting it, “standard”. And that does not mean “optional” can’t exist either.

[serene nebula]

Dumb question but does that happen on real hardware? Maybe it’s flickering in the overscan area?

Also tangent but is that the best version of TimeGal that’s possible on the MiSTer?

I played the SegaCD one and found out recently there was a port to the PS1

[stable perch]

Folks, DE25 is nothing at this time. Technical hurdles need to be overcome in order to even start down that road

[dense wharf]

my playstation 5 core on de25 is running swimmingly

[stable perch]

Not sure how the "no fractional PLLs" is going to be dealt with

[somber steppe]

Even Robby got into the hype this time. nobody is safe at this point.

[serene nebula]

That doesn’t impact me because I don’t know what that means!

[stable perch]

It means that there's a technical hurdle that needs to be overcome before the framework is possible to port to DE25.

And it may not be possible to overcome

[serene nebula]

[frail storm]

Well, I don't think so because it's a very obvious problem.
Doesn't appear on Duckstation or Mednafen.
It's not in the overscan area either.
And yes, I would say the PS1 version is the best version currently possible on the MiSTer: Saturn version is good but doesn't have so good video quality.

[chilly kraken]

maybe someone is brave enough to tinker with the dual ram PSX GPU

or maybe we wait for the next board

[dark mountain]

There are obvious issues with certain games that are visible on a real system, such as with Buster Bros, Captain Commando, Super Puzzle Fighter II X/Turbo.
Therefore, it's sometimes better to test on a physical console rather than via emulation.

The PS1 version also had some problems, if I remember correctly; sometimes it would miss an input.

[proven seal]

i think the saturn version is generally preferred for that reason, even if the fmv quality isn't as good

still though, probably worth looking into the issue on psx

[dense wharf]

until mister can play the 300gb ld rip of course

[serene nebula]

Ghost in the Shell is my favorite one. It replicates the FMVs on the side which looks very obviously broken. But sure enough, identical to real hardware lol.

Tested with an unmodded console and my original copy of the game.

[clear rock]

Dreamcast is pretty big if possible IMO, also a fully accurate N64 and Saturn core as well

[proven seal]

dreamcast is not happening anytime soon

[somber steppe]

Meh, most good dc games have been ported to gc and I wouldn't know whats wrong about n64 games or saturn games. I grew up in palworld, I'm 17% slower than normal anyway.

[proven seal]

i'm gonna have to disagree with that first statement

[clear rock]

My main concern with the "good enough" mentality is the possibility of development becoming stagnant and/or just rely on tossing more workarounds on said good enough implementation. Like what ZSNES and Project64 did for years. For the time having those working at all, and at a playable speed no less, was nothing short of a miracle. But people started to rely on those and their hackish methods for far too long after we no longer needed to rely on those hacks and workarounds

[dawn axle]

“Good enough” can mean a lot of things and from everything I’ve experienced “good enough” on Mister usually means “we’re near or at the limits of what we can physically fit in the FPGA and further development offers significantly diminished returns for the amount of effort required”

Obviously most devs will continue to try and fix bugs but after a point, these are 30 year old pieces of hardware after all, development will have to end at some point

[tropic stratus]

Look at the core here: I stopped development for it for quite some time now, considering the improvements per spend time being to low and rather worked on the n64 core instead of fixing some of the games.
Now Kuba fixed some games and issues, proving that there are indeed further improvements possible.
This is harder with gen5 then it was with other cores, but if someone really wants to and spends time, it is possible as proven now.
So yes, we are not at the limit, not even close. But the speed of progress is way slower for the last few %.

[somber steppe]

MiSTer has no limits!

[ivory verge]

I'm still working on fixing a few bugs, but research takes a lot of time, and major changes to the code require a lot of testing. My wife gets annoyed with my “missions in my head.” 🤣

[lost summit]

I have tested some games in past few days with Commando rbf and no issue so far !

[ivory verge]

thank You!

[oblique glade]

Shout out to @ivory verge 's efforts. They don't have to improve upon the experience that we already benefit from. Sincerely, thank you for for helping to fine tune the cores around the MiSTer ecosystem. Not to mention your exhaustive testing on cores like Saturn. It doesn't go unnoticed.

[ivory verge]

Thank you for your kind words, I'm glad I can help❤️

[serene nebula]

KUBA KUBA KUBA

[frail storm]

You also enjoy the testing process.. I hope! 😄

[ivory verge]

Of course ❤️

[chilly kraken]

Kuba kicks ass

[frail storm]

One question.. In Chrono Cross, the only way to fix the "Elements" menu in battles for me is activating "GPU Slowdown (U)".
The other options that supposedly works around the issue (24Bit Rendering, Texture filtering...) don't fix it.

So, what side-effects does "GPU Slowdown" have?
Games I am testing seem to run normally with it activated, but it's marked as "unsafe" after all...

[lusty coral]

PSX is probably my favourite core on the mister and as Metal Jesus Rocks says. I believe the 2xCpu core is the Hidden Gem

So it's been amazing to see these updates and bug fixes not only come out, but make the way down to the 2xcpu core

[rare gyro]

It really is impressive that such a core is available, also for the N64 core

Apparently that won't be a thing with Saturn, which is too bad.

[frail storm]

I'm not sure the Commando fix has made it to the 2xCpu core..?

[lusty coral]

Oh your right

I must have got confused with the dual sdram build

Fingers crossed the fixes get ported to the 2xcpu core

[somber steppe]

Until the gamecom core is out, right?

[tropic stratus]

GPU Slowdown is marked as unsafe because it was never really tested much. It's just a stupid way of slowing down GPU speed. Not accurate and not even a good way. More a quick and dirty hack to somehow make the GPU slower to solve issues where it being to fast causing non acceptable glitches.

A good solution would count cycles and slow down until the "target speed" is reached. But given how few games need it, this effort was never done, because even with the better solution it would still be not as good as a real VRAM replication using a dedicated memory.

[frail storm]

Ok! Thanks a lot for the explanation!
In fact, I have just noticed that it doesn't completely remove the glitches in Chrono Cross either 🙁

[tropic stratus]

Yes, i fear it's not really tuned well.

[rare gyro]

Is it reasonably feasible to fix? I haven't yet played chrono cross, wondering if I should wait

[dark mountain]

My wife does the same, but she is impressed by the MiSTer project at the same time.

She thinks I do too many "test sessions" when she sees me with the Saturn core. 😂

[tropic stratus]

the current method is just reducing the pixel throughput by 50%. Experiementing with other speeds should be easy, but then a lot of tests are needed and unless another method is used, it will never even get close to be being accurate.

[rare gyro]

True, but what about enough so that the glitches aren't visible?

[opal carbon]

Luckily with Chrono Cross there were recent rereleases on modern platforms. It’s one of my favorite games of all time and I get excited whenever it comes up here since I know there are some glitches, and I’d love to replay it on MiSTer but at least it’s not trapped on PS1 anymore!

[rare gyro]

Oh that's good to know! Hopefully there weren't creative liberties taken by those in charge of the re-releases which change the experience of the game itself

That's why I try to play original versions for first time playthroughs

[hallow quartz]

The re-release has a horrible filter over the background art that that destroys the aesthetic, I would wait until you can try the original.

[rare gyro]

Will do

And thanks for the heads up

That's something I wouldn't overlook 😅

Id kinda like to play it with psx2x, maybe that build doesn't have the same issue

[hallow quartz]

Although I could be misinformed and there is a way to turn it off, but I never saw it mentioned.

[rare gyro]

Maybe a mod perhaps

[hallow quartz]

Looks like there is an option to play with original assets, but they still look like they have a bilinear filter applied. This channels comparisons are excellent, should give you the answer to what version you will want to play. https://youtu.be/kAqSRt1QZCI?si=63XxTioKMu0MOdAu

[opal carbon]

Yeah you can turn it off

I played through the entire remaster on a Switch 1 before they added the ability to smooth the framerate. People simulatenously complained that the remaster "looked bad and ran like shit" but I think most folks don't remember the framerate on the original game was very low. Eventually Square caved and patched in a higher framerate, but you could always turn off all the upscaling / new character models. I swapped between the two, I think the new models look good in some instances but I was glad to have the option for the original assets.

[rare gyro]

You guys might have talked Robert out of fixing it 😂

[hallow quartz]

It looks like charters are still modelled in a higher resolution even with original backgrounds enabled, that mismatch drives me nuts.

[abstract drift]

i mean at that point emulate it on duckstation

[hallow quartz]

I support ports or remasters if they are faithful, but unfortunately that is rarely the case.

[opal carbon]

Nah, turning the new graphics off swaps the old character models. That's just how the game looked.

[abstract drift]

i'm guessing it doesn't render at 240p though?

[opal carbon]

Not sure what it renders at internally

[hallow quartz]

They don't look they are rendered in 240p in that video?

[opal carbon]

Totally possible that they're rendered at another resolution, certainly there would be some scaling since the target resolution is much higher on modern consoles.

It looked fine to me and I think there are some advantages to seeing more detail in the character models, there is so much detail in them.

[hallow quartz]

Which is fine, but imo there should always be an option to render them at the original rendering res too.

[opal carbon]

Yeah agree, would be nice!

But I still think it's a decent port.

[hallow quartz]

But then I still play all emulation at the original resolutions, it's just one of those things that I am particularly picky about. The exception being rendering 480i content at 480p if possible.

[opal carbon]

Yeah I'm the same way with most things. I'm just happy that Cross is not trapped on PS1 anymore since most folks are not willing to play on original hardware / mess with emulators.

A lot of effort went into that game and I'm just glad other people get to play it. Radical Dreamers too! That was a nice surprise, and I think really wasn't talked about enough.

[hallow quartz]

Yeah, not everyday Satellaview content comes to modern platforms!

[opal carbon]

Exactly!

I'm sure it wasn't a huge effort for them but the bar is so low with ports these days I was not expecting it. Ironically AFAIK the reason that Cross is not officially Switch 2 compatible yet is because of Radical Dreamers, some corruption in some of the menus I think, but oh well. It runs fine on mine.

[serene nebula]

I uhh, still haven’t played it lol

[opal carbon]

My copy is in this office somewhere!

No time like the present.

[mortal oracle]

MiSTer must win, again

[serene nebula]

Yeah, I love the PS1 and own over 400 CIB games for it, I just play on MiSTer lol

[clear rock]

Just use your Epoch to go back to 1999 and play it then

[mortal oracle]

I still love the intro to Cross to this day, it was amazing to see back in 1999 though

[dull ledge]

Which controller do you prefer?

[twin walrus]

DJ Station Pro. The silver one

[dull ledge]

Nice I’ll look for that one on eBay. Do you have a favorite bemani game?

[twin walrus]

For PS1?

Beatmania 6th Mix + Core Remix

[manic dirge]

Yeah, a Mega CD with Genesis cart slot that has 32x support could be the tower of power we've always wanted.

[timber flint]

Hopefully they'll figure out how to get the 32X layers in there. Was disapointed how the only way to run a 32X on the Mega SG was to use the DAC

[vestal thicket]

That’s tricky given how it works with the Genesis. I’d almost like to see a FPGA recreation of the 32x in its own power base-converter-like shell that people can just put onto their Genesis consoles.

Hell, I have a 32x and I’d buy one if they made the shell fit the model 1. I suppose someone could make a cart with a video connector and have it all just in a flash cart?

How does the Neptune board from…Cosam I think, work? Does it route the video internally on the board?

[proven seal]

i think all video gets combined onboard. sadly there's no way to disable the 32X side of the hardware though, so you're locked out of sega cd games if using a mega everdrive pro

[vestal thicket]

Yeah, would be nice if there was a physical toggle. Pretty sure no SMS either.

[lost summit]

@ivory verge I think I found a regression (tested 3 times and issue happens)
The commando PSX core couldn't pass the clear stage screen (1st stage) of Floating Runner - 7-tsu no Suishou no Monogatari

the music is ongoing.

With the last unstable, it shows "Now Loading ..." and pass to the 2nd stage

[ivory verge]

thank You! i will look at it

[ivory verge]

try this , thanks!

[lost summit]

It is fixed ! Thank you 🙂 What is the change ?

[ivory verge]

Thank you for noticing that! . I was testing other things and forgot to remove one condition for CDDA reporting

[rare gyro]

Oh wow what a neat project. Yeah I'm curious what the cause of this issue could be.

[lost summit]

It is not a regression same behavior with last unstable and RUNNER_FIX version, if someone could confirm this game "Favorite Dear - Junpaku no Yogensha (Japan)" shows black screen after playstation logo ? If yes I will opened an issue ticket

[ivory verge]

Just wait few seconds and game boots

[chilly kraken]

Yeah, working fine here too

[spark ermine]

MiSTer wins again

[lost summit]

For me it is not the case ... Thanks for the check I will upload again the bin/cue

[lost summit]

after reuploading the CD, it works.

[serene nebula]

Great to hear!

[fluid raft]

I was playing Silent Hill with a C-Blend core from 2025-04 and it´s looks amazing! Isn´t possible to merge the C-Blend with the updated core? Thanks!

[chilly kraken]

what is the c-blend core, precious

[ivory verge]

As for me, I don't see a problem 🙂

[digital zinc]

Composite blend stuff kuba was experimenting with

[fluid raft]

It would be great!! I love both PSX and N64 CBlend cores!!

[chilly kraken]

oh oh

I remember that

[fluid raft]

KI Gold is beautiful using the Cblend option

[abstract drift]

oh yeah what happened to that it was pretty cool

wasnt it inspired by how the voodoo3 works or something

[feral swift]

Yes, we need composite blend on both PSX and N64 cores. 😄

[serene nebula]

Dumb question time. The composite blend option is nice but can’t you get similar results with filters? Or is how it’s done via a core option completely different and more accurate?

[cosmic tulip]

Dont know exactly how to describe it but cblend on saturn is vital for me and unique from crt stuff

I actually use them in tandem

[serene nebula]

That’s really cool. I never really messed with the option but was always impressed with the adaptive cblend.

[cosmic tulip]

For me it removes the checkerboard shadows on satuen

[serene nebula]

Don’t laugh but I enjoy them lol

[cosmic tulip]

Saturn
Fuck I cant spell today

Its all good

[serene nebula]

I totally get it though, it’s more authentic imo to have the cblend stuff working in the checkerboard shadows anyways because that’s how your TV displayed it.

[cosmic tulip]

Yeah but also theres a kind of hard pixelness that the crt filters never really solve that c blend on saturn does. A softness I kind of enjoy you know?

[serene nebula]

Yeah makes sense, thank you for educating me!

[fluid raft]

Hope @ivory verge and @tropic stratus can make this happen 🙏🏻

[tender tartan]

The composite blend feature just a 2x1 box blur, isn't it. Hurts my eyes. Are people that offended by dithering?

[long storm]

Do you know where you can get the c-blend core? 🥹

[ivory verge]

#1096015979055697940 message

[long storm]

Legend, thank you 🙏🏻

[feral swift]

Unfortunately filters won't work on the analog outputs, so having them inside the core is necessary to emulate composite signal level blurring when using CRT monitors.

[serene nebula]

Oh wow that’s a great point. Is it because the analog video out from the MiSTer is too clean?

[feral swift]

You can not just do anything. I helped kuba-j with dialing in the composite blend to be as accurate as possible to the real hardware. There was actually quite some testing and effort involved in getting it to look right.

[serene nebula]

Or the cables we use too high quality?

[feral swift]

If you use mister via RGB you basically have no signal degradation. I guess you could use it via composite cables as well?

[serene nebula]

Either way that’s really cool that there’s options for varying degrees of “sharpness” for analog out to compensate for modern devices.

[feral swift]

For anyone wondering, here are some good examples for why composite blend could be necessary: https://www.youtube.com/watch?v=RyH_YN3YKNc

It really helps to smooth out textures and sprites. When you use such signal through a CRT or filters, the image becomes sharp again but still retains the smoother look.

[serene nebula]

It’s funny, for low resolution polygonal graphics with low resolution texturing, increasing the signal fidelity just makes the image worse. For me anyways.

These consoles really were built for lack of signal clarity and even took advantage of it to fake higher bit depth through dithering.

[feral swift]

Yes, I believe at least that smart developers understood the nature of the signal outputs and target monitor systems to where they would intentionally use their inherent qualities to make their games look better or at least adjust them specifically towards these.

[manic canopy]

The sharpness of RGB on my CRT started to bother me to the point that I just added 3 ceramic 2.2nF capacitors to the RGB ouputs of my SCART switch. It doesn't look exactly the same as composite but it still gets a similar effect (and no dot crawl). The caps are connected to ground through a switch so I can turn it on or off (I also added a 1.5nF option for less blur).
The composite blend filters for these cores are a bit better at blending dither/transparancy effects though. But they do have some downsides like the letter 'm' in FF9 turns into a blurry rectangle, while the caps leave it still readable.

[abstract drift]

thats a cool idea

[desert otter]

The CBlend cores were neat. I tried them originally when they came out and offered my own feedback on the PSX version helping it move along to V3.
But then I got the Pro board from porkchop and got real composite output and didn't need to mess around with that anymore.

[serene nebula]

CHAOS!!!!

Using the latest PSX core, Is there a fix for this sprite corruption for Captain Commando when you reach the first boss? Also, noticed Street Fighter EX has some minor graphic corruption on the character select screen and stages.

[chilly kraken]

try this build: #test-builds message

[lost summit]

Thanks Kuba-j 🙂

[ivory verge]

happy to help 🙂

I'm still working on 2-3 things, but it takes time.

[timber veldt]

I'm curious about the fixes, @ivory verge , are you porting from Duckstation or are you investigating real hardware behaviour?

[ivory verge]

There are no ready-made solutions, so I search for information in various places and check emulators to see how they solve different problems. Thanks to Duckstation, I managed to fix Duke Nukem. The rest is my own research.

Let's take, for example, the mirumiru demo problem, which Duckstation solved, but it doesn't work for us. I tried this approach, but something is still wrong. I need to analyze other areas as well. I think I'll get there eventually. Now I'm checking Trasher / Dave Mirra.

[tropic stratus]

This is super helpful to have someone with a fresh view on these things. E.g. your Captain commando solution I would have never even thought could be done that way.
Thank you so much for looking into it.
I still remember to get any consistent savestate for the Dave mirra crash for hours, but never had a chance. Hopefully you also have a different way to tackle it and succeed 🙂

[cosmic tulip]

I remember there were rendering issues with parasite eve. Were those ever solved?

I've just been kind of out of it the last few months and the chat moves fast

And wanted to start a run of that soon

[chilly kraken]

I dunno if that’s in the scope of stuff kuba is planning on looking at, but maybe!

It is, as far as I know, still a problem

[abstract drift]

amazing work kuba, love seeing these last few games get sorted out

[serene nebula]

Exactly this! This is genuinely the best community in retro gaming.

[chilly kraken]

IMO Kuba’s name should be blue

Just throwing that out there

[fluid raft]

I think Chrono Cross has some issues too

[cosmic tulip]

Alright I'll stick to duckstation for that then

[mortal oracle]

Yes. Justice for Kuba!!!

[dark mountain]

I second this.

[dull ledge]

Having issues getting guncon to work with psx core? Which steps should I follow?

[dull ledge]

Should just switch to snac port 1 but not working. I’m thinking either the guncon or adapter is faulty. Don’t know how to troubleshoot. I guess get a ps1 controller and see if snac is working first

[clear rock]

I haven't tried using light guns, but isn't there an RCA port on the PSX SNAC adapters to sync light guns? Also, you're using a CRT right?

[dull ledge]

Yes. I’m using the rca video port and guncon 1 with snac adapter.

I set the controller to SNAC1. I run point blank and doesn’t detect anything.

I know the SNAC port works so it’s either a setting issue, faulty snac adapter or guncon. O double checked with the guncon owner and he mentioned that they tested it and it was working.

[quasi idol]

Turn the CRT Contrast/Picture setting to max

[hybrid raven]

Is the 11/19 Test build older or newer than today's unstable? Or they're identical?

[still palm]

you should just need to turn on SNAC for whatever port you're using, and plug the rca into the the yellow port in snac. You could try to plug it in elsewhere in your video chain. You could try turning the brightness up. Does it act like shots fired and just doesn't hit?

[dull ledge]

It doesn’t register the guncon at all. It might be the guncon. I noticed the last two pins are pushed in. Especially the 8th pin. About 25% pushed in

[clear rock]

Do you have a real PSX to test it in?

[dull ledge]

No. I’m going to return it on eBay and try to buy another one

[mortal oracle]

Woah! @ivory verge fixed the MGS sound?! 🤯

[ivory verge]

i think partialy 😉

[mortal oracle]

You’ve come a long way from fixing misspellings of disc

[ivory verge]

Can anyone compare the sound of Codec with Duckstation?

Unfortunately, I don't have time today, I need to spend time with my family. Big thanks!

[ivory verge]

Thanks! My heart is blue 😉

[chilly kraken]

I'd give you mine if I could. You're out here fixing PSX...I just swap sys folders :p

[ivory verge]

It doesn't matter who does what, the important thing is that we all help

[rapid garden]

mister wouldn't be where it is today without its community 🙂

[frail storm]

Thanks for working on this historical core! And for fixing MGS none the less... probably one of the most important games on this system.

[light cloud]

Dave mirra the maximum seems to crash a lot faster than original release.. inconsistent timing until crash tho so not sure how helpful

[ivory verge]

It depends more on luck. Sometimes, for 15 minutes, I thought the game was running fine without any problems. Other times, I'd experience lag right from the start. There were no changes that could have broken it.

[chilly kraken]

Metastability?

[light cloud]

Really wonder what the trigger is in the audio stream... I thought it was maybe solved with the recent changes, and was working okay with Dave mirra for a bit, then went to the maximum and did a few loops around the indoor area then crash

Way back I remember background audio muted would bypass. Or setting CD drive to force 1x speed

[ivory verge]

The stuttering is random, MotorOn and IRQ introduce variable delays that disrupt sector timing.

For example: One sector is delayed by 5 ms → the game retries, resets seek → the drive pauses for 50 ms → the next sector arrives too early → IRQ arrives in the wrong cycle → the game loses track of the logical state of the drive

I'll try to fix it, I already researched the topic some time ago.

[mortal oracle]

Is this because of the memory of the DE10, or slowdown reading from the MicroSD?

[ivory verge]

Changes to the code are needed

It doesn't work quite right.

[feral swift]

I can check it out by next weekend if nobody has checked it by then. Unfortunately this is the busiest time for me in the year.

How did you fix the codec sound? I believed the issue to be a result of aliasing distortion with the core.

[bright girder]

Quick question: would a usb foot pedal mouse thing work as a 2nd controller in the ps1 core for time crisis?

[somber steppe]

Awesome to see all these psx updates. Is crono cross on the cards as well or is there a more fundamental issue with that game?

[mortal oracle]

Best core gets better

[hallow quartz]

That issue is with the DE-10 nano's limits.

[mortal oracle]

I’m not advocating anyone spending any time on it, but it would be pretty neat if Virtual Pool 3 were fixed. I had that game back in the day and was hoping to play it again

Hopefully it gets fixed incidentally one day

Some audio problems iirc

[clear rock]

MGS's sound wasn't playing right on the PSX core?

[cosmic tulip]

problem with reverb during codec calls is all

not enough of it

[vestal thicket]

What issues are you having with Chrono Cross?

[somber steppe]

I haven't tried it myself yet, but it's known to have some graphical glitches #1046940919607345272 message

[round crag]

I believe those glitches are there on duckstation too

I did two playthrough of chrono cross a while back, and I've got a strong memory of elements menu glitching in battle. Unless it's been fixed recently

[runic edge]

Wow! I've never seen this before. It really does look and sound awesome!

Relaxing!

[tribal sorrel]

Sounds similar to me, but my audio setup is quite different (tv vs pc)
I did run this core alongside PSOne hardware on the same TV and there’s a noticeable difference there - slightly more reverb on your core rev with that codec tuning sfx. But much improved from the previous core.

[somber steppe]

That would be interesting as a software emulator shouldn't really be resource constricted.

[ivory verge]

thanks for testing!

[cosmic tulip]

just thinking about it
That's a lot of bugs fixed in the last couple weeks

awesome

[serene nebula]

If people didn’t find them, then would there be bugs to fix? Think about that!

That's the thing with the three that falls in the forest... it DOES make noise, even if nobody is there to hear it 😄

Congrats Kuba!

[clear rock]

Technically, there's no support for 2 player destruction derby XD

( no, I'm not seriously asking for system link support )

[mortal oracle]

I completely forgot that existed

https://en.wikipedia.org/wiki/PlayStation_Link_Cable

and more compatible games than I expected

[clear rock]

What about THIS nonsense?

[mortal oracle]

I’d rather have a Nokia 3310 snake 2 core 😎

[clear rock]

Nah, a Tiger LCD core would be superior

Dare I say it, even a Tiger Gamecom core

[serene nebula]

Thanks brother, you kick ass

Could these fixes get migrated over to the 2X core or is that asking for a lot?

[cosmic tulip]

It probably can happen but there is a question of wait till he runs out of stuff he can fix then port it over if feasible, right?

[serene nebula]

Makes sense!

[clear rock]

Was it really that big of a feature? I personally don't recall anyone ever using it

Also I would imagine it would not work well at all over Bluetooth or Wi-Fi, SNAC would be possible since there are enough pins on the port, but that don't mean losing controller support

[abstract drift]

among my friend group the link cable was incredibly popular

so many hours of red alert, duke3d etc

iirc robert said the core side is easy he just didn't want to get into designing any hardware for it

in theory you could connect two misters with a usb A-A (the most cursed one) cable between their snac ports

[abstract drift]

it probably varies from game to game wether they'd tolerate it

[dull ledge]

having issue with the psx core, any time i make changes in the settings for the core ... my wireless dual sense no longer works in game but menu etc is fine ... if i restart everything works again ... if i load a manual save state i cant use my controller in game afterwards

anyone had this issue before?

I found out if I click the track pad on the dualsense I can toggle between slot 1 analog and slot 1 digital and starts to work again

[cosmic tulip]

Do duckstation cheats work in psx core?

I really want to see if the 60fps patch for Silent Hill Works

[clear rock]

Thing is, on top of what others said about potential issues with wireless, doing it wired can allow for linking a mister with a real PSX for link play. It would be a lot more versatale that way than a method which requires two misters.

I really don't see the value in doing this wireless, trying to make a wireless device that works on a real psx sounds like it's just adding complexity and problems. Aren't people generally going to be playing near each other anyway?

I mean, they don't really make PSX controllers anymore either but SNAC adapters are popular

It's a LOT more work to make said dongle than to just make an adapter to use the serial cable

Does the serial port even supply power at all to power such a dongle?

It is apparently possible to tap into traces on the PSOne to add a serial port

Wireless would though, again, be a mess most likely

Oh wait, nevermind, that's to add one for debugging homebrew, it dosen't function like a link cable

[abstract drift]

does silent hill already hit 60fps in like, one or two tiny rooms?

i'm thinking of the like tiny featureless cube rooms in the hospital

[dull ledge]

For final fantasy 7, it is native digital not analog. I am using a dual sense. Anyway to force analog for digital only games?

[abstract drift]

using snac?

oh sorry you said dualsense

iirc if you set the virtual pad to digital controller instead of dualshock then your left analog stick will also be dpad

it wont actually be analog ofc its just a simple mapping to dpad directions

[chilly kraken]

there is a keybind you can do to swap between the two I believe (analog and digital)

[abstract drift]

that changes the dualshock mode, that wont do it

it has to be in plain digital pad mode

[chilly kraken]

ahh ok

[clear rock]

AFAIK on real controllers if the game didn't support analog you could not use the analog sticks even in place of digital

(And apparently a few games that claim they supported analog just mapped the stick to the d-pad anyway and didn't actually have analog controls)

[abstract drift]

Yeah this is a mister exclusive trick

Actually you get the same on real hardware with the brook wingman

[bright girder]

Libcrypt sounds like an underground library lol

[ivory verge]

yes, but it is an important element for some games, especially PAL versions.

[serene nebula]

I mean, its a pretty badass name

[ivory verge]

yeah 😄

[dark mountain]

Like for 2 weeks.

I remember people in my college years having a cracked version of MediEvil like 2-3 weeks after the release of the game.

Using CopyWorld website back then for finding the crack/trainer.

[obtuse dune]

Clone CD with libcryt support was out very soon after Sony released the first game with that extra protection.

There aren't that many libcrypt protected games anyway. Mostly the heavy hitters.

[somber steppe]

I had a copied game lent as a kid that only ran in b/w and didn't know why. Was some dbz game. Now I understand it was ntsc and our pal tv didn't take kindly to it.

[somber steppe]

I didn't even know what that was at the time and most people here still think scart is shit because we only ever used it with those composite to scart adapters that came with every console.

[hallow gorge]

scart is shit

[somber steppe]

Wasn't rgb scart pretty much the best way to hook up your psx though?

I still got mine hooked up to the rt4k with a packapunch rgb scart cable. Looked really good, just as good as mister.

[abstract drift]

its the best way to hook up ... most retro consoles i expect?

[somber steppe]

Unless they support component afaik.

[clear rock]

I thought RGB was better?

[abstract drift]

it usually is unless the console supports 480p in which case its usually exclusive to component cables (xbox, ps2, gamecube)

[proven seal]

you can get 480p from a PS2 via RGB if you have something that supports sync-on-green, which is unusual

i think original xbox is the same way. gamecube and wii i'm not sure though

that being said, component is nearly indistinguishable from RGB on a good CRT or scaler

[proven seal]

wonder what game compatibility with that is like. i assume anything that has a 480p mode would work?

could maybe get even better results with GSM

[somber steppe]

3rd party hdd adapter? I have the gamestar adapter. This just got interesting.

[proven seal]

i think it's a bit limited right now, but you should be able to load games at the very least. it's a nice update

super cool that you can boot PSBBN into 480p, means you could leave your PS2 connected to a VGA monitor without having to use any scalers or adapters. admittedly though, i've not had much luck forcing 480p in games designed for 480i

[somber steppe]

Seems like something to look into in a year or two.

[proven seal]

seems to work better with some titles than others. i could never get klonoa 2 looking good on anything other than a standard CRT at 480i

[abstract drift]

i think Okami has a good 480p mode, they're kinda rare, was more of a late-gen thing too

[clear rock]

I recall one of the God of War games having a cheat code for some kind of 512p mode or something like that

I'm glad I managed to fix more than I broke 🤣

[coral minnow]

well probably not quest64 but you know, generally

[timber flint]

Looks like the foreplay scene to a porno 😂

[serene nebula]

As a filthy casual; this just as accurate as a real PS1 and it's way more convenient to use and play games on. I have over 400 PS1 games collecting dust on a shelf because of this core lolol.

[frail storm]

I'd say the Chrono Cross thing is the main offender remaining. And workarounds don't work-around it if you reload the game 😛

[cosmic tulip]

I believe the only major visual bug I know about is parasite eve. But I never checked to see if it got fixed

[somber steppe]

Parasite eve is a Christmas game anyway, I'll see if I can play it this month.

[proven seal]

PSX is in the top 5 best mister cores for sure

can someone refresh my memory on the E2 errors? is it an issue with the core do they just occur naturally

[ivory verge]

E2 - CPU exception(only relevant if game shows issues)

No freeze than all good

[proven seal]

nice, that's good to hear. i've run into it a couple of times but never had issues beyond that

[tropic stratus]

It was mostly from the early days. It shows a CPU exception like divide by zero.
In most cases these are either unhandled or unexpected and the game will hang afterwards, so it would be a hint for me to search in the CPU for issues.
Today the CPU is probably stable enough and the cases where it happens, it would happen naturally and the game can handle it.

[somber steppe]

Btw why do I get flashbacks of murdering a million crows in central park when thinking of parasite eve? Was that a thing?

[serene nebula]

No it actually happened. You made the national news.

[dawn axle]

Yeah it was really fucked up but trump pardoned you during his first term

[clear rock]

Ah yes, I remember that, the Murder of a murder of crows

[frail storm]

Oh man, I come here for this kind of stuff 😄

[exotic knot]

@tropic stratus do you think is a good idea adding the PSX DualSDRAM to the nightlies? I don't remember if I asked you this a while ago already or not, tbh. But I guess it could be useful to check whether that setup still works

[chilly kraken]

it does. i believe it's in alt cores

[manic citrus]

no, I think he meant the auto builds

alt cores is just a database people are plopping builds into

still standing on ten toes that you're all weird for trying to make dualsdram psx core a thing

It’s less accurate than the single ram build so I don’t think it’s a good idea.

[serene nebula]

So what you gain with more accurate sound that is impossible for the human ear to even perceive, you trade for less accurate GPU timing that has a noticeable impact.

@exotic knot So in its current state, I don’t think offering a less accurate core with zero appreciable improvements but noticeable downsides is a good idea. Just my opinion here, take it or leave it.

[exotic knot]

I know the dual sdram it's not meant to be released as official, but as a experimental build I don't think the nightlies is a bad place, it could be a way to test that it doesn't get broken over the commits

[serene nebula]

Oh ok then ignore me, sorry

I forgot he mentioned that dual sdram could be used for a more accurate GPU if developed more which is really cool

[river otter]

yeah same dual build setup like with the Saturn would be sweet

[manic citrus]

right now all you're doing is adding more steps to debugging when people do have an issue

[river otter]

idk feels a bit better than it being in that altcores repo?

just my opinion, I actually don't feel that strongly

[serene nebula]

I only care about what Zakk said. I think it’s a cool ass experiment and maybe a good foundation for an improved GPU.

Sorry I am way too opiated on this when I have nothing to do with it. I’ll refrain.

[chilly kraken]

my secret hope is that kuba starts poking at the GPU on the dual ram core

[ivory verge]

I think now is a good time for a new stable core. Six games and the music player have been fixed, and an option for old GPUs has been added.

[lost summit]

Great job 🎉

[ivory verge]

I'm working on other things, but it takes time. I also have a lot to do at work at the end of the year and I don't know when I'll have some free time.

[tacit fox]

@ivory verge you’re doing the lord’s work! Thank you for keeping the dream alive! 🙏 ❤️

[oblique glade]

TY, kuba-j!

[ivory verge]

Nah, I'm just trying to help, but it's also fun for me. Thanks guys

[chilly kraken]

You want me to build some cores? Happy to do that if you’re busy. We can also potentially promote the unstable if folks have tested it

[hallow quartz]

I've played a bunch of games on the unstable in the last week or so and not noticed any issues, seems solid.

[somber steppe]

Think Chrono Cross could be fixed via patch like the games on the n64 core?

[serene nebula]

What’s wrong with it again?

[ivory verge]

https://github.com/MiSTer-devel/PSX_MiSTer/issues/244

[serene nebula]

Sorry lol, I always forget we have GitHub issues

[ivory verge]

That's the easiest way to explain it 😄

[serene nebula]

Known workarounds: Turn on 24-bit Rendering or Texture Filter, which will result in slowing down the GPU and clearing noise.

Seems pretty good!

[lusty coral]

Could I please make a request. Once a new stable has been released with these amazing changes and fixes.

Could we also get a 2xcpu version.

(id attempt it myself but I haven't got a clue. I do have a pc if that helps)

[somber steppe]

It's not chrono trigger. That's what's wrong.

[somber steppe]

This will get released when the game.com core is being released.

[chilly kraken]

yup, once kuba tells me how he wants to do it, I’ll get to work

[ivory verge]

I'll leave it to you, you can build good cores 🙂

[chilly kraken]

I need to look at the audio, make sure it's not distorted

[lusty coral]

Sweet Ty kindly. You also have a gold name so congratulations on that.

Please @ .. me when you have made some and I can test them. Like we was doing before

[fluid raft]

Thank you so much! Any chance to add c-blend too?

[cosmic tulip]

Can psx do user database text files like n64?

Because that can be an effective way to enable workarounds like the solution for chronocross to just force enable 24 bit rendering

I really hope whatever next incarnation of mister we get we get per game settings we can save in core

[hallow quartz]

I use the setname parameter in mgl's to handle any per game or set of game settings like that.

[cosmic tulip]

The documentation around mgls are terrible

[brisk sentinel]

Hey @chilly kraken I don't see an issue report of this but I've noticed what I think is an audio bug in the PSX core. In the first battle of FFIX, if you listen to the sword slashes of the boss or Marcus, the slash sounds have a rising "zing" sound that I don't hear on real hardware. I found a video of it here

https://www.youtube.com/watch?v=0Gk9oL088G0&t=4m25s

[cosmic tulip]

Have you played on the most recent test core with audio fixes?

[chilly kraken]

this is on the test core

or maybe not, nevermind, I can't read dates

[brisk sentinel]

I can try later tonight with the latest fixes. I heard this on the current stable

[cosmic tulip]

The question is can these fixes be ported over to the 2xcpu core

I mean they can but will they

[hallow quartz]

I asked here and people helped me understand things, it's honestly trivial to setup. Want me to send you a dm with an example mgl?

[ivory verge]

There are no fixes for MGS codec etc. in the current unstable version. I'm working on it, I have another idea

this is not the final result, just a trial run

in audio video section there is new option

[chilly kraken]

Latest unstable sounds like this https://youtu.be/UT9_U3LId7A?si=64sdOBpdrilSZ-EU

[ivory verge]

spu filter

eliminates metallic reverberation

I need to refine it and add a few things.

[chilly kraken]

If anyone would like to test for themselves

[cosmic tulip]

Unfortunately I am at work right now

[chilly kraken]

This build feels good to me. No sound issues that I could detect. Meets timing

If folks could give that a whirl

[chilly kraken]

If you're wondering how 2xCPU compilation is going...

I don't think she is gonna meet timing, champ

[chilly kraken]

(she did not)

[cosmic tulip]

Well fuck

[chilly kraken]

Fear not, I am not so easily defeated

[chilly kraken]

This is not one that has met timing, but can someone look at this and confirm:

• its the turbo core (I want to make sure I merged the changes correctly)
• it has all of kuba's fixes

[brisk sentinel]

This fixes the sound issue in FFIX for me, sounds like the video you posted

[chilly kraken]

https://github.com/MiSTer-devel/PSX_MiSTer/pull/334

[lusty coral]

Should be able to give this a test for a bit later today

I can't remember if I used specific games though.

[chilly kraken]

duke nukem. i remember duke nukem

[lusty coral]

Ah yes that's to see if it actually is 2xcpu. Thanks for reminding me.

[lusty coral]

Right. I have confirmed it's the turbo core. I compared duke nukem time to kill. When you spawn in without moving you get an average of 20 FPS with the normal core

Your test turbo core gives me 29-30 fps

So yes I can confirm it's turbo

Unfortunately I'm not sure what fix I can easily test

[clear rock]

What does "met timing" when compiling a core mean?

[chilly kraken]

ok, let me know if this works good for folks and then I will put it in the alt core db

[lusty coral]

Will try to test tomorrow although I am busy on the weekend

[dark mountain]

No regression so far on multiple Final Fantasy games.

[tropic stratus]

Thank you again @ivory verge for all the work you put into the fixes. It's still a micracle how you dig into the core and solve all these issues in such a short time.
It makes me so happy to see that the core is still capable of more.
Also thanks @chilly kraken for the new release build and pull request, i just merged it.

[somber steppe]

I'm grateful for every fix, as it puts chrono cross more in the crosshairs of future fixes.

[mortal oracle]

Chrono Cross comes behind Virtual Pool 3

[somber steppe]

Even if so, fixing virtual pool will leaven even less games to fix and brings chrono cross closer it's own fix.

It's inevitable.

[frail storm]

Yes! In fact, Chrono Cross was programed in japan! Possibly manufactured there, too!

[odd glen]

Whats wrong with Chrono Cross???

[ivory verge]

https://github.com/MiSTer-devel/PSX_MiSTer/issues/244

[odd glen]

Does the 2X core fix it as a work around???

[fluid raft]

If I turn on 24-bit Rendering or Texture Filter, will it break other games?

Or is it safe to keep it turned on?

[chilly kraken]

you know what you must do...

[ivory verge]

What I have on my to-do list will keep me busy for a few good months 😛

[mortal oracle]

I think they’re safe

But embrace original hardware

(Well the settings that match original hardware)

[rare gyro]

I love that we're still seeing progress on this core even while Robert is doing other things

[cosmic tulip]

I wonder if this silent hill cheat would work on 2xcpu

[lusty coral]

Id be surprised it would be smooth, as I believe even with 2xcpu and turbo mode enabled. There is some frame rate drop. However, I've only played 10 mins into the game on Mister

Although

I wonder if there's a 30fps cheat for duke Nukem time to kill and land of the babes

[cosmic tulip]

We actually discussed that a little while ago in here
There is but the logic is tied to the framerates and the game speeds up

[ivory verge]

Dave Mirra / Trasher fix , please try this:
I spent so many hours on it that I almost went crazy, now my brain is stuck and the game works fine (propably) :)))

[lost summit]

is it contains MGS fixes ? or different build ?

[ivory verge]

Different build

[ivory verge]

There will be further corrections to this code, and there may also be errors in other games, which is why I am not including it in test builds. For now, please only test it in Trasher/Dave Mirra. Thank you!

[light cloud]

Ill test it out soon! Thank you so much @ivory verge 🤘🤘🔥

[ivory verge]

Okay, I cleaned up the code, now there shouldn't be any regressions.

[hollow stratus]

What’s new with PS1?

[ivory verge]

New stable release and now trasher and dave mirra fixed

[cosmic tulip]

which warhammer game?

[hollow stratus]

Ahh I see

[cosmic tulip]

ah
