about that d-pad

#

I noticed pokemon reds sprites are flickering when using sgb enhancements. Is this normal behavior?

north ice
#

It looks like the pokeball palette is being used for the Sparrow palette. I think that might be a Pokemon bug

#

R/B are notorious for their bodged code, so I wouldn't be surprised if when the pokeball bar is being loaded/unloaded the sprite palettes are being changed in a silly way.

Does this happen every time, is it reproducible?

hard sinew
#

This vid, according to the description is captured from a snes with a super gameboy via ossc and doesn't show said behavior:

#

Rival battle starts at 4:20

Could you replicate the behavior? Just to make sure I'm not too stupid to get it working correctly. 😅

#

I take it this on the GB core with the SGB palettes enabled, and not the actual SGB core?

#

because yeah I'm pretty sure I've never seen that playing through on real SGB hardware

#

Yeah it doesn't happen on the sgb core, though it's a shame still that the palette in the gameboy core doesn't work quiet right, especially since it allows you to disable the border.

#

Also the ar seems a bit off.

fathom trail
#

What osd settings are you using on the regular game boy core?

hard sinew
#

I tried both direct video and 1080p output

I also tried resetting settings

#

I could try nuking the entire gb core settings file.

Do you have the top level super game boy set to palette or on? I just want to make sure everything matches

Probably just a rt4k issue SureSure

I tried both, it's just the frame that's different, right? Also, I've tried 1080p output to make sure it's no rt4k thing. Also also, I tried different roms, german and english from blue, yellow and red and all have the same green flicker as shon in the video https://cdn.discordapp.com/attachments/1046941428758102086/1263170127650885735/20240717_182308_1.mp4?ex=669c8e1a&is=669b3c9a&hm=c4a2d6b550497f3274b02d27ee7c7b45143d81d10313162125cb6fbcf6b0a839&

Tried different older versions of the core to the same affect. I'll try a new .ini file when I get home but I'm running out of ideas.

hard sinew
#

@fathom trail I did a completely fresh install on a different sd card and guess what! It still flickers. Are you, Sir, 100% completely sure that the sprites don't have a green flicker as shown in the video when you have the sgb palette turned on in pokemon?

fathom trail
hard sinew
#

I'm on my mental health walk now, just wanted to make sure since it's so odd. Maybe it's de10 dependent like the grandia flicker on saturn?

Maybe someone else can try it also?

Also, pls fire up the gameboy core with the sgb palette enabled to check if you get that green flicker in pokemon red as I do.

#

So unlike my vid? #1046941428758102086 message

#

Then it must be de10 specific. I tried different sd cards with different installations, one completely new.

#

Different roms from different sources and different regions as well.

hard sinew
#

@rotund flume could you provide me with the .ini file you used when you tested it to make sure it's nothing in there?

fathom trail
rotund flume
#

Oh, I tested with the Super GameBoy core

fathom trail
#

So there is a distinct difference between the sgb core and super game boy setting on the game boy core?

#

The github says sgb core is based on the snes core

#

So is the game boy one less accurate?

rotund flume
#

The Game Boy SGB implementation is missing features such as audio enhancements and other SNES required improvements.

#

It just gives you the border and custom color palettes.

hard sinew
#

Yeah but the sgb core doesn't look quite right when it comes to ar and you can't disable the border. I know it's more accurate to oem hardware, but maybe the gameboy core can be fixed so you have more options. (That work correctly)

rotund flume
#

Likely no since to get that extra functionality it needs the SNES hardware and that core pretty much maxed the de10. The SGB core stripped out SNES core features to get the SGB stuff working.

#

But I’m no core developer so I dunno blobshrug

hard sinew
#

Maybe still worth a github report. I don't have an account though.

So is jumping off a cliff but you don’t see us doing that!

#

Finally gave the Neo Geo Pocket core a shot. And hoo boy that one was not easy to figure out. It's so weird that it's in the arcade folder!

#

Anyway, it was fun trying out some of the games. Cotton is so weird playing in grayscale. Hopefully we get a Pocket Color core some day, and one that is more finalized in general so it's more intuitive. Obviously this core isn't finished yet though, so I get it.

rotund flume
solar iron
#

Yeah, it being in the arcade folder is super weird. Even just getting games to boot on it took me awhile to figure out.

Someone will maybe just port it to the MiSTer framework

I haven’t read the license of the original, but I wonder what the “etiquette” is there. From my perspective as a user, I think it would be a positive though

arctic solstice
#

Differences from the color versions isn't as cut and dry as I thought. b/w Puzzle Link is JP only, but looks slightly (and I mean slightly) better on the monochrome Pocket than the color version, which still looks very good on the b/w pocket. Baseball Stars color feels like a newer revision than the b/w version and has a better palette on a monochrome Pocket than the original b/w version (palette is too dark in the original version). Pocket Tennis is an oddity. Color one went all fancy with updated graphics, but is stupid easy. I prefer the b/w version, but it still pales in comparison to Nintendo and Camelot's GB and GBC Tennis games.

#

I still have no idea why Puzzle Link 2 is color only. It doesn't look as fancy as other color only games.

#

Nice game, though.

#

That's all I can do, we need a dev for checking the problem.
By chance, we could reproduce it quite easily with the first battle in the game.

hard sinew
#

It's in every battle I've seen.

#

I did a romhack of red and first thought I messed something up while testing but the original does it as well 😅

uneven rover
#

probably worth adding to the issue that it doesn't happen on real SGB hardware or the SGB MiSTer core

#

so you know, it's clear that it's a real bug with the GB core with SGB palettes enabled specifically

wraith magnet
#

Might want to try on the N64 core using Pokémon Satium and virtual transfer Pak and see if it is present there. Does the GBA core play GB games?

uneven rover
#

I don't think Stadium has any bearing on this issue, it uses its own bundled GB emulator

hard sinew
#

Afaik gba core doesn't play gb games. Even on a real gba there are extra chips for the gb games present. There is a little notch on a gba cartridge that isn't on a gb cartridge that hits a switch when inserted to trigger which chips are used.

#

Also works fine on stadium (which is software emulation on n64 afaik) and the sgb core. Also tested it on jp red, blue green, german red and blue and American red and blue. Also tested it on different core versions (picked 1 per year) and it was there since the very implementation of the feature it seems.

uneven rover
#

even if it could I imagine the GBA core would play them in CGB mode, not GB (with SGB palettes), as per original hardware, so it would be a different kind of colourisation altogether

hard sinew
#

True, gbc just assigns colors to the gray scales while the sgb for pokemon specifically does that really weird coloring of sprites dependent on which Sprite is being shown.

I played through Card Fighters Clash on my Switch awhile back, and it was incredibly fun.

hard sinew
#

No jrpg or nice adventure games?

gray grail
#

Mostly sports and fighting games.

#

Evolution: Eternal Dungeons is an RPG.

#

Biomotor Unitron too.

#

FYI the core isn't totally ready at the moment :

  • Samurai Shodown freezes on the title screen;
  • NGPC support is really, really limited with outstanding bugs and no color on sprites and background.
solar iron
#

Yeah, I tried it out like a month ago, and it was super rough. Even just getting a game to boot is like solving a riddle wrapped in an enigma.

#

I've tested a compile of the core from today.

solar iron

Plus it's weird that it's in the arcade folder and not in the usual place.

So the progress in GitHub doesn’t reflect the actual progress

I'm just glad that it's moving along. It'll be ready when it's ready.

Just the initialization that remains weird compared of other cores.

solar iron
#

I assume the latest updates are for patreon members only still right?

gray grail
#

You need to set up the BIOS and the RTC before launching any games.

#

NGPC is Patreaon only at the moment when I read the code (beta stage).

gray grail
#

EDIT : I've incorrectly recompiled the NGPC core, I had a NGP core that tried to initialize NGPC games before.
Now it's much better, thanks for the reminder @mild glen

#

Sonic gonna go fast now. 😁

fathom trail
#

Shout out to jotego for being the arcade core king, I should really try the ngpc core

gray grail
#

The NGPC core is quite fun on some games.
I've finished Samurai Shodown Pocket 2, done the 3 first worlds on Sonic & 4 stages on Rockman - Battle & Fighters.
Done some balls on Neo Turf Masters.
Quite solid except some incorrect colored tiles here and there on Sonic.

Some games are failing though : like Fatal Fury when first stage is appearing, KoF R2 freezes when entering the stage too, Capcom vs. SNK - Match of the Millenium fails quite heavily, same for the two Metal Slug in-game.

#

With a 8bitDo controller, the feeling is quite right (having microswitches on the stick, like on the original console).

How can I edit a palette for the gameboy core?

vital hull
hard sinew
# vital hull I too want to know this

I messed around with it and the answer as always is hex editing. Seems the 4 palettes are just hex values in the file. There are tools online that convert your selected color into a hex code you can punch in.

#

I like my dmg palette just a smidge more contrasty so I customized the standard one to be a bit brighter on the 1st palette and a bit darker on the 4th one.

gray grail
#

EDIT : By doing some 'archaeology' from 2023, I've found my technical answer.

Around here for the discussion back then #1046941428758102086 message
Endrift added some SIO tests to the suite 3 months ago and I tried them yesterday night.
All failed on the current core revision.

torn jay
#

are they important? SIO sounds like no-care unless for multiplayer

gray grail
#

Not important for the core.

#

As you pointed out, only valid for multiplayer and I was only commenting on the fact that Endrift had added these tests in recent months to the rest of the Test suite.
Suite which seems to have already been tested on the GBA core in 2023 and commented on.

Hi there! I'm trying to get two different roms to load their own saves on GBA2p (two different pokemon games, for trading purposes) is this even possible?

It's possible but a little bit complicated maybe. Could be you need to combine the save files yourself

I'm having trouble launching "Metal Slug - 1st Mission" on the new NGPC beta core from yesterday.
And I've seen PCN playing a little with that game on the Analogue Pocket in a earlier live video last week.
But does it work also on MiSTer for you too @left breach ? Just to be sure that's general and not on my hand.

The game never worked for me -stuck on the blue SNK logo -.
I've already verified my ROM file and even redumped my original cartridge after that + checked the CRC32 value against the database (same value as the file on the Net).

Jotego updated the NGPC repo a couple of hours ago.

Maybe run the updater again.

I still haven't updated myself yet (work and whatnot).

I still have the alpha from a couple of weeks back.
I remember it looked like I needed to do a bit of setting up for MiSTer. That's why I went Pocket for the Stream.

#

@torn jay Now that your MiSTer Lynx core has been ported to the Analogue Pocket, and since the Pocket's screen is limited to ~62Hz, I was wondering: since this is an FPGA implementation, why is the "Sync to 60Hz" option cause audio distortion? I mean, shouldn't it simply make the games run slower since the system clock is "hacked" (as in altered to match the 60Hz)?

torn jay
#

sure, if games run slower, the audio will also

#

best for lynx is not synced, but triple buffered

toxic cargo
rotund flume
#

Maybe just a bug introduced by the porting process?

torn jay
#

i guess the issue is that the core will pause for 1 frame every 4 frames, causing the audio samples to not be equally in time distance. Could probably fix that with a buffer that is long enough for 1-2 frames

#

however, the feature was only added for basic compatibility. Overall i would never use it, but some people (especially with CRTs) really wanted it

#

Oh, and of course on the pocket you must use it, i guess, as 75 hz is not possible

#

And maybe not enough memory for the triple buffer? no idea, i haven't looked at the pocket port

pulsar trench
#

I am playing Lynx on the Pocket core without "Sync to 60 Hz". It seems to work fine. I think it might only be needed on the Pocket for some games or demos.

toxic cargo
toxic cargo
#

At 60Hz I mean

torn jay
#

yes, it would add about 16ms of sound lag, but as you drop every 5th frame, you got 0-16ms video lag anyway

#

to be honest, i would just not use it if the triple buffer method is available

None of the games load for me in the NeoGeoPocket core. I assume you need to be a Patreon subscriber to get that working?

I've found my problem on Metal Slug 1st Mission when watching PCN just a moment ago.
You need to use old (dirty) sets of ROMs with save files embedded to the flash memories for those games to work on the core.
Newer sets of ROMs done with a colleague some months ago, with clean save files don't work with the current core.

gray grail
#

Seems to be the same problem with The Last Blade, but I will need to retest.

novel kindle
#

do you know what are the changes of this newer set ?

gray grail
#

We dumped fresh new cards and/or save cleaned the flash chips.

#

So no save inits present inside the ROM files, as the originals cards were keeping save files inside the ROM too (like 3DS Type2 cards).

novel kindle
#

so maybe an issue to create save in certain cases or the state of the rom is not recognize by the core

gray grail
#

Those newer ROM files were working on the previous beta core.

#

I've left some comment on an issue to Jotego's Github.

#

Yeah, that's why Miki (at JT) only see a blank screen with newer ROMs and I see the game booting with an older ROM file.
But I will need to check with @left breach in DM later as he seems to be able to boot and play the game normally (and I can't).

gray grail
#

I have fixed my issue on some games.
We must use the most older sets of ROM files coming from the pirate scene back then (so, NI set before 2016 and the beginning of the whole redumping process).
And there is an issue for initializing some save process in the current beta core. That's why we need ROM files with save inits already done.
At least for Metal Slug 1st Mission and The Last Blade / Bakumatsu Roman on my tests today.

Do you guys happen to know why unstable-nightlies for the Gameboy/GBC core always fail to load the GB/GBC bootrom?

I messed around with it for a few minutes and it does seem there's a difference in behaviour between latest stable and latest unstable

With latest stable, even if I move my BIOS files out of games/GAMEBOY and power the MiSTer off/on, I still get the 'Gameboy ®' splash screen
With latest unstable, it will only show the splash screen if the BIOS files are present
the boot1.bin that update_all gets (GBC BIOS) didn't make a difference, it was my manually copied/loaded via bootrom menu bin files that needed to be there

Perhaps your BIOS files are no good? Mine are:
GB_boot_ROM.bin MD5 32FBBD84168D3482956EB3C5051637F5
GBC_boot_ROM.bin MD5 DBFCE9DB9DEAA2567F6A84FDE55F9680

#

deleting the /config/GAMEBOY.*, no splash screen in unstable until I manually set it via bootroms menu
presence of /games/GAMEBOY/dmg_boot.bin didnt help

toxic cargo
strong sierra
#

yes, there seems to be a difference
I copied those BIOS files to '/games/GAMEBOY' and loaded them in the bootroms menu.
update_all gets /games/GAMEBOY/boot1.rom, which is the GBC BIOS

#

I'm not too sure why, but the unstable core seems to need the DMG BIOS loaded manually to show the splash screen, the stable doesn't

#

probably related to the sameboy BIOS somehow like you mentioned (I thought that looked different to the stock one, but perhaps not here)

toxic cargo
strong sierra
#

just once.
copy the bios over, load it, save settings

toxic cargo
#

There's something else: update_all downloads "boot1.rom" to /media/fat/games/Gameboy/boot1.rom, but that's the Gameboy Color boot rom (dbfce9db9deaa2567f6a84fde55f9680 md5sum).
Isn't that wrong?

#

I mean, it downloads the GBC boot rom to the GB roms directory, but it doesn't download the GB boot rom anywhere...

strong sierra
#

I agree, it does seem odd 🙂

toxic cargo
#

Well, releases work as expected, so I guess rising an issue doesn't make much sense

north ice
#

I didn't realise update all downloaded any roms for the gameboy. That's not necessary because the GB, GBC and SGB bootroms are baked into the. rbf file.

strong sierra
#

Yeah, it (boot1.rom) doesn't seem to do anything unless manually loaded
For me, after deleting config/GAMEBOY.*:
Splash screen shows with the stable release and no BIOS manually loaded (or present in /games/GAMEBOY)
Splash screen doesnt show with unstable release, until a BIOS is manually loaded within the core

#

I had a the BIOS files copied over and loaded from years back, so the behaviour in unstable seemed the same as stable at first (until I deleted config files to test)

toxic cargo
uneven rover
#

If that’s the case then something might have gone wrong? Looking at the changes since the last release nothing looks intentionally related to the bootroms

north ice

This reminds me of a small GBA issue I've not yet raised an issue for.
Someone made new events for the GBA Pokémon games writing data that can be sent via e-reader cards. The code is written in some low level programming (thumb or arm, can't remember).
Works on real hardware and "some" emulators. Typically the emulator issue is ensuring the GBA bios file is there.
On MiSTer, with same BIOS, I have issues as is the case for some problem emulators.
I need to document properly, but I wonder is this BIOS use by GBA core, or perhaps some unrelated feature not yet in GBA core

torn jay
#

e-reader isn't implemented at all, maybe even base hardware register functionality. So if that is required somehow, it will not work

#

bios you must provide yourself. The baked in BIOS is...well, it has some issues

#

(not wanting to blame there, writing a GBA bios that is fully compatible is no easy task and i'm happy we have a opensource one at all)

sterile quarry
#

I'll get some saves together for an issue sometime soon hopefully. From loading the game you can reveal the issue very quickly.
The whole custom events are all open source on GitHub too which might prove even easier to make sense of it you'd already see hardware aspects that are not in the core

Which I now see Robert has also mentioned. 🙂

I was talking about GBC specifically

tacit mural
#

@fierce tangle maybe best not to remove the GBC bios. That's kind of why I brought this up in the first place. There's a reason the core still asks for the bios files.

sterile quarry
#

Incidentally with the GBC bios I was able to do speedrun RNG manips in the Gen 1 Pokémon games, so great to see how accurate it all is ❤️

wraith magnet
#

But regardless, as a rule of thumb best use official BIOS rather than open source, unless there it is confirmed the open source one is better. This isn't the case with GBC and GBA as far as I am aware

tacit mural
wraith magnet
#

Definitely the GBC BIOS should be included in the BIOS DB, that is the one people should be using, the bundled in one is just in there to get the core working really. If anything it would be better to remove that open source one from the repo and require people to use the official one

torn jay
#

GB and GBC bios is far less important for game behavior, as it's "only" a bootrom and can only influce state and timing at the very moment the game takes over.
GBA bios is called many many times in the games as standard library for all kind of functions and therefore will influence state, behavior and timing all the time

#

The baked in GB and GBC bios is coming from Sameboy and at the moment there is no bug/wrong behavior known with them, so I see no issue in using them

ashen bone
#

Is there a way to fix GB fast forward from glitching the screen or is that a quirk of FPGA? I have the GB core set integer scaling and when I hold FF it glitches out, randomly switches between that, original and full screen.

torn jay
#

set "Stabilize video(buffer)" to on

north ice
#

To put this to bed, the GBC bios/bootrom is very basic and has well understood behaviour in initialising a bunch of registers. The open source reimplementation ensures this is done, while also offering alternative functions such as fast boot or loading games into GBA mode.

Game behaviour should be identical for both the bullt-in and original ROMs.

#

Feel free to do what you want though.

I noticed that on the gba core the world map in golden sun flickers all the time. The flicker disappears when frame blend is turned on. I know this doesn't happen on a real gba, so I take it frame blend on is the accurate setting?

torn jay
#

yes it is, but for many games it looks worse due to the delay and ghost effects. I think golden sun does that to increase the perceived resolution.

deft jay
#

@torn jay will we have a preview or a teaser of your new GBA game before Christmas?

torn jay
#

hopefully. I'm very busy currently and while i have a playable version, i really need to improve it in some points before i want to share it

frank pasture
#

Probably a stupid question - are you using your own core to test things? 😅

torn jay
#

I develop using my own GBA emulator, but I modified it in a way where I stripped out the emulated CPU, but compile and run the code natively. This allows me to compile it in 1 second, debug it fully on my windows machine like a native program and still have mostly accurate behavior in terms of graphics and audio emulation.
Longer testing sessions I do on Mister with my core and note down things that i want to change. Currently I usually still note down 5-10 wanted changes in 30 minutes of play, so you can see I'm still not fully happy with it.
Sometimes I test with a real, unmodded GBA and that is really a bad experience. I already added a gamma option into the game to allow for brighter colors, but it's still hard to see stuff well enough on the screen, especially when a lot is moving. However, I don't want to scale down gamespeed. Having a fast paced action-rpg like gameplay like modern titles have was the goal and I really want to have it as close as the GBA allows it with it's controls and visuals.

hot sparrow
#

the gamma option will be nice for using on things like the analogue pocket original display modes

frank pasture

That’s a super cool methodology. Thanks for taking the time to explain it 🙂

Is the NGP core working? I'm getting visual glitches upon boot and can't seem to load games. I had it working at one point but still had visual glitches.

It does work for me. You need to manually place the bios on the games directory.

solar iron
# gloomy dove Is the NGP core working? I'm getting visual glitches upon boot and can't seem to...

This might have to do with the bios your running? I think the old version of the core (that was in the arcade folder) was using a Neo Geo Pocket bios. But I haven't been able to fine one of those online, and I'm using a Neo Geo Pocket Color bios now. And some of the color-based games that used to run on the core before now either don't run, or do with glitchy visuals. Probably because the bios is trying to boot them in color mode now. At least that my theory anyway. No clue if I'm right.

solar iron
#

Just found a Neo Geo Pocket bios (not color), and yeah that fixed the visual corruption I was seeing in some of the color games. So the Color bios definitely was the problem on my end. That said, the new black/white bios seems to have introduced issues of its own? Like control just seems to not work when booting up a lot of games, and when this happens, it also kills control even within the bios menu. It requires a full reboot of the core to fix it. Very odd.

frank pasture
#

I haven’t read JTs patreon posts for a little while, but seems like the core still has some work to go

gray grail
#

Try with some older dumps.

frank pasture
#

Hope JT manages to get that issue fixed after you pointed it out to him

gray grail
#

I had the problem with Metal Slug and Last Blade, the clean dump don't work on inputs.

#

The 'dirty' dumps with a save already initialized work on the core.

frank pasture
#

Overall compatibility is still low though, right? Or is that just because people were using the newer dumps?

gray grail
#

Both.

#

Some games have issues, like Fatal Fury as it needs some IRQ work on the core.

#

Some don't boot like Pac-Man.

frank pasture
#

I’m not sure if anyone has said this, but I’m really glad you take the time to test these cores and provide your input - it really seems to help move things in the right direction 🙂

#

I appreciate it 🙂

gray grail
#

I'm not a powerful player in general, but with years of experience now in bea testing programs and also software emulators, I know quickly what we need to test and how.

#

So with some quick screening methods, I could sometimes even be faster than automated tests.

frank pasture
#

The work you’ve done testing the Saturn core and linking up the developer of the SCSP tests has almost certainly accelerated things there

gray grail
#

I know, I see it also as a challenge, for myself. For helping a project that I care, even with my small part.

#

But, simply as experience with my real job, I know that testing efficiently could help speeding up processes for developers.
And we need bidirectional trust.

#

Communication is an important key.

frank pasture
#

There are so many roles that support any effort, often it’s a lot of the background stuff that goes unnoticed, but it’s hugely important

gray grail
#

So the core could work even partially. I've seen software emulators for that console 'working' in a way poorer shape.

Just been testing GBA core rumble using a GBA/DS style Rumble Pak (in this case the DS Pak in a GBA using "GBA As Controller" homebrew with GameCube Link cable, via a WiiU GameCube to USB adapter)
#controllers message
After testing, I'm wondering if the rumble is being sent as on/off osciallations N64 TPak style, or if this is tuned to more modern controllers.

The novelty of using the hardware Paks is great, and feels fine. But swapping between DualSense and GBA/DS Rumble Pak revving the drill against a wall in Drill Dozer, I'm not sure if it is the same.... On dualsense the weak to strong effect is clear, but with the GBA not so much. Curious if this is potentially an implementation thing, or I could just be noticing incorrectly!

Dragonball Z is such a rich IP that’s perfect for gaming, yet all the games (and there’s a ton) absolutely suck.

I can't get a single game to work on the NGP/C core myself. Can someone tell me where the BIOS files go and what they're supposed to be named?

it has trouble with the most recent No-Intro roms (something to do with the flash memory saves)

shadow rain
#

thank you for sharing the name of a set that works, but yeah, I haven't been able to get anything working either. As was discussed before, it sounds like the issue is that "clean" roms with no save initalized don't work at the moment, so older dumps that aren't cleaned up do work

gray grail
#

That's what I've left to Jotego through the issue log some weeks ago.

#

We redumped the whole NGP/C set some years ago with two other collegues in the preservation community.
The core does not like these files with uninitialized save flags at the moment.

#

The core needs to add the support for saving games correctly in the future, like how other software emulators and flashcards work nowadays.

#

My BIOSes are inside a "ngp.zip" file, under 'mame' folder & organized like that.

image.png image.png
#

That should cover NGP and NGPC games with their corresponding BIOS.

remote carbon
#

Why under mame folder? I thought bioses should be placed in the games directory, I have mine inside the neogeopocket folder.

gray grail
#

The NGP public core is already correct with the NeoGeoPocket folder.

That needed an exception under the JT framework from what I remembered, as all other works from JT were under the 'mame' folder.
The NGPC core isn't ready (yet ?) with the correct folder, if my memory goes well.
As long as it works like that since months on my systems, I've not changed anything.

ebon night
gray grail
#

And the extension isn't the same.

#

But it works.

ebon night
#

And it's required to have that kind of hierarchy?

ebon night

The NGPC core is under heavy WIP, there is not uniformisation at the moment.
When you follow the history of the dev time, you can understand partially why it's like that and a remain that needs to be cleaned later.

Jotego will move it once it’s out of beta. Needs to be in the mame so it works with the beta key

GrafxGray always seemed close enough (by memory/nostalgia rather than reality) to act as a GBP palette for me

Regarding GBA SNAC, I didn't follow all the previous conversation, but curious if I understand correctly that the existing GB SNAC connector would work as is some day? Excitedly planning (just in case it gets added) to look at getting some link cables

If (that is a massive "if") the GBA gets SNAC support, then yes the current GBC SNAC board would work

But Robert has said he wouldn't work on this, and nobody else seems has said they would be interested in working on it

mild glen
#

Would be interesting to see a potential GBA core rewrite with the knowledge Robert got when developing PSX and N64

wraith magnet
#

That would be interesting to see what benefits there could be there. I assume if he did it would be as a stepping stone to doing a DS core on a future board. Either that or a major refactor before implementing the elusive "Shrek mapper" 😉

sterile quarry

Thanks for the answer moondandy. For sure only wondering on the off chance it would happen someday, certainly no expectation there. The hardware potential is great to have in the back pocket though.

#

My understanding is GBA SNAC would be a lot more complex to implement than GDC, but I am no expert. @steady wasp may know more, he is an expert on all things SNAC.

steady wasp
#

yeah I was hoping the existing GB snac would also work with GBA. I had some linking in gba working with it. I got sidetracked and never finished it though. Robert wrote some support for linking in his GBA2P core, it wasn't perfect or complete. I just used that as a base.

#

I would say it's probably more complex than regular gb linking because there's alot of different modes, and it handles 4 devices instead of 2.

Not sure if that would make it any easier, but even if it was limited to just 2p would be great so that you can trade your Pokemon away 😄

Trying to get the sgb border for crystal clear to show up but I’m guessing since it’s a gbc game the core might not be seeing it like bgb or other sw emulators can. Patched it with sgb mode enabled, and have the gbc core with sgb on and sgb + gbc on. Any tips/confirmation that it wouldn’t work?

#

(It’s got a dynamic sgb border depending on game state, so I’d lose out on all of that fun jazz if I decided to make a static one)

oop, misremembered. Doesn't blackscreen, just throws up the gbc-exclusive error.

#

Does that rom hack work as intended on original hardware? I guess a ripped cart into a Super Game Boy?

open shuttle
#

Since there is no SGBC there's no hardware for it to work on :p I was hoping the sgb+gbc mode of the gbc core would allow the border to come through

sterile quarry
#

Ahh, sorry, my bad, I guess the Super Gameboy only boots GBC games that have GB mode, I'd not thought how the GBC exclusive worked even though you mentioned it

#

I guess I was only wondering if there is any specific use case the rom hack designed a border for? Wondering if it could be emulator only by virtue of how it was coded, without any intention of meeting some real hardware requirement at all

open shuttle
#

Yeah game itself requires gbc specs to run. The game sticks your party members and badges in the border, and colors it according to your dex color settings

sterile quarry
#

It's not Stadium 2 compatible is it? Not even sure how that would work.....

open shuttle
#

The sgb build isn’t

#

Non sgb build works in PS2 on hardware but doesn’t have a custom border

sterile quarry

I wonder is the border just not behaving in line with any hardware then so would make sense if MiSTer doesn't support it perhaps

I would expect it to work with sgb+gbc option turned on, is the odd part. It’s definitely not a huge surprise to me if it just won’t work with the core as it is today.

I wonder did anyone test back then? No idea how many revisions the mod goes through, but might be worth testing one around the date of the fix noted in that issue. Nice one to spot the game specifically checked in that GitHub issue

open shuttle
#

Unfortunately testing older versions of the hack is difficult, SS doesn't leave previous revisions public AFAIK. Tested the latest CC on a variety of GB core versions (including the one linked in the issue) and no dice, going to solicit help from the CC discord

open shuttle
#

It’s CC’s devs stance that it’s the core’s fault. He intends to try and fix it for bgb (latest version of bgb broke compat with how he does sgb border) but if that doesn’t fix it or he can’t figure out a way to fix it, he’s not going to put any effort into it.

I’m guessing a change made in an older rev of cc broke the sgb border behavior in the mister core, but improved behavior in emulators.

#

(Not to say I think he’s lazy for not wanting to dig into this, he’s openly stated that he has moved on from CC and will only be doing critical bug fixes where necessary, instead focusing on other ventures)

rotund flume
#

I mean if all other games work but his doesn’t, it’s pretty clear the issue is on his end.

open shuttle
#

Well, it's not exactly a real standardized feature and he acks that the way his game does it is exceptionally shenaniganny.

open shuttle
#

Guessing from recent bgb breakage and comments in the gh thread, the root cause might be the lack of wait period in the romhack after sending the sgb update command. Not sure how to port the Ips patch forward since I don’t have a copy of 2.4.0 to compare it to

open shuttle
#

Figured it out. It doesn't work in the mister core for the same reason it stopped working in the latest BGB I presume - the game doesn't wait long enough after requesting an SGB update to move on. Adjusting the timer to be longer (first tested with FFFF and it worked in both) made it load right. I've let the developer know, hopefully he gets a hankering to cut a release with the timing adjustment in it

rotund flume
#

For what it’s worth, I appreciate you putting in the effort. 🍻

open shuttle
#

IPS patch for 2.4.0 build gave me a huge hint, I sort of just bumbled my way through bgbs debug menus to find something that looked like a wait cycle near an sgb transfer command 😎

#

The fact that the patch only modifies one value made it a lot quicker to narrow down where that logic could exist in a newer version

#

There’s still an odd issue where, on the mister core and allegedly mgba but NOT bgb, leaving the Pokédex garbles the sgb border. Pressing select with the main menu open re-sends the border and fixes it though.

#

Probably another timing issue where the palette used to draw the border is modified too soon before the request is sent to refresh it (leaving the Pokédex updates the borders colors to match your dex settings in CC)

Consoles cores are much complex than arcade most of the times and there are roadblocks on how the JT framework could perform + motivation/understanding of the system from the team.

#

At the moment, I've seen some regressions on the last update, as The Last Blade and Neo Turf Masters can't work anymore.
Most probably some updates are needed on the save functions and how the core should keep them in memory/write them on the SD card.

yeah, I am really waiting on the ability to save

#

NGP core had some regressions that carried over from the NGPC core like borked inputs on some games.

gray grail
#

Borked inputs could be related to save functions.
The NGP/C games have a tendency to lock out when the save file couldn't be created/read, like a copy protection (I don't say it's one for sure).

#

I've seen that when we begun to redump the games on the two systems with clean/just opened box games, without any save flags initialized on some older emulators.

#

Same with some previous versions of the NGPC cores, I've left a note to Jotego on the issue tracker.

#

Now, even some save initialized games don't reply anymore with inputs at all, same issue than with the clean dumped games files before on the previous core revisions.

i couldn't get my rumble cartridge to work though i think that's prob the adapter

hot sparrow
#

ah so cool. i even got rumble to work

sterile quarry
#

Very cool to see someone else try this!

#

I think there might be something going on in how rumble is implemented, but I wanted to do more testing to confirm.
If anyone has like Drill Dozer to confirm how it rumbles, but I think it might be implemented in a modern controller way (working with a Dualsesnse) but missing some rumbles with a GBA hookup (or N64 Rumble Pak?). I'm guessing perhaps the core isn't sending the rumble as on/off pulses as I believe N64 core does.....
Need to test more to ask a better question of a core developer!

hot sparrow
#

it's really good with the cube controller

#

i mean i guess it should be tho

sterile quarry
#

I'll have to test later tonight. IIRC, the fainter rumbles I could feel on Dualsense (or probably Gamecube, I could try that too) were absent on the GBA setup

hot sparrow
#

the gba pack is quite subtle, even my insidegadgets one which is supposed to be stronger (i don't have a way to compare them just going by reddit...)

#

i also deleted my mister and linux files recently so my settings might be newer. i'll have to retest the nso n64 controller and switch pro

sterile quarry
#

It's a interesting one to test.
Sadly without a cartridge Drill Dozer readily to hand, you'd struggle 100% to know what it "should" do

#

I found it very odd testing my PSX SNAC (without voltage correction), that not only was it weaker, but would also just not represent some rumbles at all due to that weakness I guess.
But also, MGS played on my PS2 rumbled differently to the apparently correct PSX core. Never would have guessed there was a difference there! 😂

Is the interframe Blending in the GBA core comparable to that of the Original AGB-001? Or is it closer to the more ghosty AGS-101?

#

Additionally, how much input latency is added with the stabilize video option for the GB/GBC core?

torn jay
#

little tulip
#

So looking at the blending in the gba core, it looks so much more ghosty than an actual AGB-001.

torn jay
#

the main reason for it being there is to fix the blending of two consecutive frames for e.g. the map in f-zero or shadows in some games. For that it works fine.
There was no analysis of how many % old vs new image should be in the blend that i know of, otherwise we could adjust

# torn jay the main reason for it being there is to fix the blending of two consecutive fra...

Yeah i understand and it does work but the image becomes ghosty, way ghostier than an original AGB-001 (original Non-SP model GBA) which has a fairly okay pixel response though the intended effects in F-Zero games and Golden Sun still work there.

I suppose the core's ghostiness in the frame blending option is closer to the ghostiness of the AGS-101 (GBS SP brighter) which has a worse pixel response than the original GBA model.

I didn't see it mentioned in the patreon update

the issue is that if you don't do 50/50, it will still flicker for games like f-zero and then you can get "burned in" pixels on your LCD ( i had this one time, where the fzero map was visible for multiple hours after leaving it on for 5 minutes, thankfully the screen got back from it)

Do you think it would it be possible to implement a turbo feature to prevent slowdowns?

torn jay

which core do you mean?

flat violet
#

The Game Boy core.

rich mason
#

no, you will suffer super mario land 2 as it was intended by god

torn jay
#

The big difference between GB and GBA for turbo is that GB depends a LOT on correct timing. So many games have issues with wrong timing even with single digit % differences from the original speed.
because of that, turbo would lead to issues or crashes. in many games.
GBA is much more forgiving, that's why it has a turbo option(about 2.5x cpu) in the core and still being able to run most games.

Testing the waters of a potential feature request, a border option for the GameBoy core.
In attempting to get decent colour samples of my GameBoy Pocket (looking un-naturally green here), I noticed that on the core and most everywhere else, there is no representation for the little border of I guess always off pixels.
I added 6 pixels top/bottom/left/right for the example, makes it look a bit more like my GameBoy I thought!
Could be either the lowest palette colour (as GB Pocket, don't have an original GB), or black (to give the GB Color impression)

#

can anyone fill me in about why some handheld cores play in fullscreen over analogue and some don't?

#

Atari Lynx runs in fullscreen for instance

#

that's not the case for GB or GG

#

is it a matter of resolution or how the core upscale?

#

I suppose NGP runs in a window? It currently doesn't support analogue vidoe so I can't test it

full adder
#

also is there a way to play 2player GBA using two CRTs?

fading scroll
#

The Lynx is 160x102 normally, so if you consider a 2x scale that's 320x204, fitting in 240p

#

GB and GG are 160x144, too tall to fit in 240p

full adder
#

ah makes sense then

#

I suppose its the same for NGP

#

at least some games from GG have been patched to work on SMS

primal lichen
#

That uneven scaling for Game Boy titles is also why the Super Game Boy has the borders. They knew that trying to upscale the resolution would of cut off the image, so they instead kept the original resolution and compensated with borders surrounding the game.

Funny that 2x144 = 288p, perfect for PAL 😄 If only you then could keep the rest of the image correct, or at the right refresh rate I guess

This is really cool, something I never considered before, but I suddenly see the true reason the Lite controller exists. Might have to get one now! 😄

#

Trying to rack my head to come up with anything different I could put together with bits in the house, but got nothing so far.....

hot sparrow

tbh i may have been looking for a reason to justify owning it, i mostly just bought it bc i thought it was cute

sterile quarry
#

It is too. Is it a nice controller to use in general?

hot sparrow
#

surprisingly yes

#

like it's not switch pro controller nice or anything but there's nothing wrong with it and for it's size it's as good as your average handhelds controls

sterile quarry
#

Sounds decent alright then. I guess the intended use is for two different "d-pads" at once, one traditional d-pad as you'd expect and the Switch style button taps rather than a d-pad...? Even in their little trailer nobody seems to be using the "right stick d-pad". So odd looking

Mind if I share that image elsewhere? I know a Klonoa fan that would get a kick out of it!

(Just via a discord that is. If you are social media inclined, that's a hot post for yourself waiting to happen right there! Get all the wonderswan fans to come out of the woodworks)

hot sparrow
#

lol go ahead but bear in mind that the mapping might not make sense as i used the way mister describes it to make it easier for us

#

in practice it is like this, not like the mapping diagram bc the core rotates and swaps controls around automatically (assuming i didn't make a mistake... its confusing)

My go-to Klonoa expert seemed to think it looked fun, after having their brain twisted at first (same here!).
Her previous strategy was to hot-swap controllers when the orientation would change, which is probably the typical user option without this controller I imagine

the way the analogue pocket handles it is probably simplest but this is probably a bit better as you can slam down l and r in final fantasy games to run from battles like on psx

@torn jay In the issue we discussed some weeks ago (this one: https://github.com/MiSTer-devel/AtariLynx_MiSTer/issues/22) you said that the core video out is trimmed to 59.2 Hz, while the core is faster internally.
What's the internal refresh rate of the core then? Wouldn't it be possible to simply change 59.2 Hz to the internal core refresh rate?

Also, why 59.2 Hz? Is it because 59.2 Hz is "standard"?

torn jay
#

unlike e.g. GBA, the refresh rate of the Lynx is not fixed anyway, so it will be hard to get it perfect through all the available games

#

Maybe for a pure HDMI out mode, but together with analog out it will be a big pain and a lot of work (and testing)

hot sparrow
#

I’m curious how the pocket will handle lynx with its built in core (using the adapter I think has yet to ship). It will have to conform to its display which is pretty standard frequency I think whereas lynx is not?

torn jay
#

as far as i know the display cannot do 75hz, because it wasn't able to do that with the wonderswan core. So it cannot do that for lynx as well. Best possible is triple buffer then

toxic cargo
torn jay
#

yes that would be relativly easy. However, if you want to stay completly in sync with the lynx you would need to adjust to the current update rate of the game, which will likely cause a sync loss every time it's changed

toxic cargo
torn jay
#

it's not that easy, because the video clock is different from the core clock, so it would be pll + hsync + vsync timing

#

some games use 50 hz, some 60, some 75 and even weirder refresh rates, so having it fixed will always lead to not perfect results unless the video out directly changes to whatever the game wants

#

we could add that mode, as i said, but it will lead to screen resync whenever the refresh rate changes and some games change it e.g. from menu to ingame

#

could still be an improvement for many games

toxic cargo
torn jay
#

well, psx games do that but keep the overall timing. Only 240p<->480i has issues but could be solved with the sync 480i hack. For lynx with completly disjuct refresh rates, it would be like 240p<->480i without sync 480i.

#

Haven't seen anyone with a screen that can keep sync for that with vsync adjust 2

full adder
#

speaking of Lynx. One of the coolest thing about that core is that it's probably the only handheld that outputs full screen on a CRT

toxic cargo
torn jay
#

it's not that easy. the display_dma module would have to generate video out timing directly without the framebuffer at top level

#

you can try to feed some generic vga timing generator with the clock of the module...

thankfully the hdmi scaler is very friendly and will basically accept anything that makes sense somehow

hard sinew

I don't remember to be honest. I think it was gb but I changed it to gbc so the core would automatically load it as gameboy color

But if you set the core to gameboy color instead of auto before you load the rom it should work just the same

still oak

hard sinew

On most things it doesn't matter, but mister uses the file extension to load the correct gameboy version

I guess since mister is hardware emulation it needs to know as which gameboy to boot before loading the game.

Just playing some WonderSwan for the first time, fun system!

Wonder, is there a way in INI or something to set the HDMI screen size to be the same for horizontal/vertical orientation? V-Integer scale seems to fit a different scale each way! Would be reducing the horizontal size, but figured it might be nice for any cases of frequent switching.

Also curious what exactly "Video Timing for YC" does if anyone minds sharing. I've enabled this mode and play on CRT is great. I've left "Buffer video" off, and not noticed tearing to my eye

# hot sparrow there's a border option but it's for the vertical size not the horizontal

Tried a few things to get WonderSwan scaling to be the same for horizontal/vertical orientation switching. Wonder if it is worth adding a feature request?
My TV would take up to 1440x1080 (with issues), but I couldn't force a square aspect through to solve the scaling. Other than the vertical border in option (you'd need horizontal), couldn't find anything else that seemed useful.
Maybe a 4x option, almost like the 5x option on a bunch of cores only here to keep inside the display but reduce the horizontal size... Hard to think of something more general

Wonderswan core seems to do odd (understandable!) things with controls when the screen rotates.
From experimenting, it seems when "auto" screen rotation would kick in (regardless of setting), whatever is mapped to D-Pad in the core (X1-X4) becomes Y1-Y4 instead.

Is there any way to disable this? So you could map X1-X4, Y1-Y4, A+B and have those buttons stay consistent, regardless of screen rotation?

Playing Klonoa and was trying to map controllers I could rotate in my hands as the wonderswan does, but I don't think you can do that currently. Even using secondary mappings, the problem is X1-X4 should be "MiSTer D-Pad" horizontally, but loses assignment seemingly when the game goes vertical.
Is this correct? Trying to understand before making a request on GitHub

I was using yours to make sense of it yesterday!
I wondered if any DEV is around that might confirm what is happening with some of the auto orientation switching. Saw a request is already up for a button to change the orientation (that would be neat!).
I think it's only changing the D-pad in those cases......
Not so familiar with the library but if there are other games that either require switching orientation often, or optionally to play any time, they'd make for a good test case

#

Could be a hardware issue, or you could be seeing issues due to being out of date. What mister stack are you running, and have you run update_all recently?

heady gull
#

I just ran update_all again this morning. I'm running the Taki Mega Pack(128MB+USB+Fan+Analog Video board)

wraith magnet
#

What ROM pack are you using and did you copy using FileZilla? If so did you have it set to binary?

heady gull
#

I was running the No-Intro set for GB stuff since I don't have an Operator yet for my carts. And, I just transferred things directly to my SD using my PC

wraith magnet
#

Can you get any games to run properly? Did you let update all add the BIOS files for you?

heady gull
#

Yes, some games run properly. I have been trying to see if it's specific to mappers or not.
I am 90% sure I have the BIOS search/update setting on for update_all, but I will double check real quick

#

Checked and I did have BIOS updating enabled. There was also an option for bootROMs as well. Can try that as well.

heady gull
#

Still no dice, it looks like

wraith magnet
#

Very odd. It shouldn't effect anything, but are your ROMs zipped?

heady gull
#

Yeah, my thoughts exactly. Shouldn't be, will double check

wraith magnet
#

I am out of ideas, but be good if someone with a Taki board could confirm they can play these games OK

sterile quarry
#

One idea, are you using the "Game Boy" core, or say, GBC core. Not sure across the board, but for a few, it seems those deviation core versions might not pull the bios using update_all

wary fjord
#

I believe the gbc “core” is just an mgl that loads the gameboy core and points to the gbc folder

sterile quarry
#

If past experience like the WonderSwan colour core is anything to go by then, it points to the colour folder, and perhaps finds no bios there. That can be an issue, not to say it is the case here, but has happened to me

I've already finished these games on the GB(c) core this year :

So not a problem with the core itself, but there is a problem elsewhere with the configuration.

I'm noticing separate ROM folders for GB, GB2P, and SGB. What's the logic?

Super Game Boy is a separate core entirely. So that's needed. Not sure how the 2 player GB core works, as I never tried it.

I know they're all different cores but the ROM sets should be the same.

#

I'm super impressed by the idea of the SGB core

You can do that on your own

Because they are different cores they will have different folder structures

You can use symbolic links to have the GB2P referencing the same folder as GameBoy

# gray grail <@101523181826756608> Could you try with the latest 'unstable' version of the co...

Apologies for taking a bit to get to this.
I have the unstable dropped onto my SD now, but I decided to try other tests first before going to try it(about to do that now)
But, I went ahead and tried some other things first, just in case. Those were:
A- Trying a different ROMset
B- Manually placing my backup BIOS files onto the SD
It seems like A alone has done the job, but I forgot to try just new ROMs before then moving the bios files over, so I am unsure if it's A or B fully.

Still, testing the old ROMs again, they're messing up after the boot/bios screen even after assuring I've loaded the correct bootrom, so it must just be some oddity with the other set

open shuttle
#

Weird, never knew specific romsets for that system could be busted.

heady gull
#

I've had that one set for so long that I don't remember what base it was from. But, I still need to check the No-Intro one now as well.

#

The ones that I tried first are from the Cyle's pack

quartz vale
#

Can you checksum your ROMs and BIOS?

quartz vale
#

@heady gull

heady gull
#

Is there a tool for that?

frank fox
#

Wondering if anyone can give me a little Wonderswan help. Installed it via update all, but after I try to launch any game, I get this weird mini gamelist window for a moment and then just back to the white rectangle

quartz vale
# heady gull Is there a tool for that?

Lots of programs can do it. 7zip can if you're on Windows. It's just a mathematical operation on the bits of the file that returns an apparently random string of letters and numbers, but will return the same string if the files are the same. That way we can verify that the files aren't the issue

heady gull
#

Well, that wasn't much of a tutorial or guide to exactly -what- I should be doing 😅
But, I suppose I figured it out?
And, according to at least CRC32, they do not match.

quartz vale
#

Fair enough, it's just hard to give a tutorial when I don't know what hardware you have. Sounds like you figured it out, though. The two files aren't supposed to match because they're different files. I'm asking you to share them here so we can compare them to ours

#

(the checksums, not the files, that's illegal)

heady gull
#

Well, just being like:
"in 7zip, just navigate to the file you want to check, right click, and use the CRC option(any tbh) to check both different files and see if they're the same value" would have been all that's needed!

#

Googling also led me to the fact that No-Intro actually has a checksum database that you can use to verify as well

quartz vale
heady gull
#

Considering it's a file operation, I'm surprised there's not just a program that can do it.

quartz vale
#

It's a pretty standard command line option. That's how I do it, but I use Linux.

#

Anyways, do the files match?

heady gull
#

My office/workbench machine was Debian, but is just Ubuntu now. But, I am also not in the office right now 💦

heady gull
#

oops

#

But yes, they did not match.

quartz vale
#

The database?

heady gull
#

The one that was correct and actually worked on the core matches No-Intro's database. The one that was different was just something else entirely

#

Still have no idea how it happened, but do appreciate all the help. Just means I have a lot of cleaning out of seemingly corrupted files now

quartz vale
#

Happy to help. It's definitely one of my favorite tools for diagnosing these issues

Is there any way to have RTC working for GBC/A games? I'd assume that's difficult since the mister doesn't have a battery, but I was wondering if there was any sort of pseudo-following when checking change in time since last startup

You can buy an RTC module for the mister

Probably because he hasn’t played card fighters clash.

Makes you realise how lucky we are to have any of the cores though. Even when you get a talented dude like Jotego who seemingly “struggles” to keep up the motivation to really get something over the line. (I hope it’s not too critical to say that - I think he’s said as much himself)

Oh totally

I think the only thing that's a bummer is that, because jotego is "working on it", it's likely no one else will

I dunno. There aren’t a whole load of devs in general. The most obvious candidate is busy doing other things 🙂

I prefer romhacks tbh. Pokemon games are designed to be incompletable and create fomo in a way. I've heard good things about yellow legacy. If you're partial to red&blue there is an insanely popular red romhack, DX violet, that comes in both original graphics and a color version that uses gold&silver sprites.

Depends on what you want from your romhack, really. The legacy series has changed most move pools, stats and some events to feel more modern and streamlined. Other romhacks just added qol changes to preserve the original experience while lifting restrictions like event and version exclusive pokemon.

Yeah, I'm just going to do more research. I wouldn't mind something that has qol changes, but only them.

There seems to be a lot of romhacks so I'm bound to find something

Hey guys. Playing around with the Super Game Boy core and love it. Definitive way to play the OG Game Boy games as well as in GBC Mode. The only issue is that it's missing the frame blend option that the standard Game Boy core has. There are probably more examples, but Wave Race and Chikyuu Kaihou Gun ZAS have non-stop flicker. Is it possible to add frame blend to the Super Game Boy core?
