@tropic stratus How's it going with the cop0 update implementation on the debug functions? Always willing to help debug or test things whenever I can. Once it's implemented, I'll finally feel confident in buying a super station one to replace my failing PS1. Ill send them an invoice for helping contribute to the core š¤£
This is a hardware limitation. What fix would you like to make in this case?
I couldn't tell ya, since I've never tested it for myself
I don't own an MiSTer FPGA system yet, but I do know a whole lot about reverse engineering games, emulators and the OG PS1. So, just by people reporting back to me, I can usually figure out what is going on, and help devs
I don't recall, I'm not around there as much. I mostly contribute to the Duckstation code database. But any find like that is really cool! Sadly some games really don't play well with higher framerates. So I've been really enjoying using lossless scaling. It's some form of AI interpolated frame generation, actually looks really good
sorry, didn't found the time yet to work on it. I will do it, just cannot promise yet when exactly. Hopefully still in january. Sorry š
kuba can rest
maybe one day...
thank you, also updated da P

Delaware, baybeeeeee
very cool rat tbh
https://www.youtube.com/watch?v=HNtefWOnWWk Ah! Have some cheese, rat!
It's an adapter bought on AliExpress. I don't like having the memory in slot 1 because it forces me to use the controller as a SNAC as well, and I can't access the menu to make save states or speed up the game.
I may or may not have identified an issue with analog control in Mega Man Legends 2. Maybe someone else can confirm.
In Legends 2 (and the Legends 2 demo) the analog control for the left stick seems to be misreading inputs constantly. Very noticeable if you just run around in circles; Mega Man will stop and turn around constantly Sometimes the character will walk instead of running for a second as well.
Iāve tested two controller so far, neither of which have demonstrated drift in the past, and one of which is Hall Effect.
My original PS1 controller connected via snac does not have this issue.
I donāt know if there is a way to calibrate analog stick control on MiSTer, if that would solve the problem, or if itās a way the core is interpreting inputs for this game.
Update!
The issue IS there on Snac as well, but for some reason didnāt show up at first. Eventually it developed the same problem, in the same directions: North-west and South-West. Disabling snac and re-enabling snac made it work normally again for now.
Now test it on real hardware
Also, likely worth checking that control in the advanced input test core to double check that the analog sticks arent doing anything funky
Is that a core I would have to download, or does it come installed on regular builds/update_all?
Come with the update_all cores.
Go to cores-> utility->input test
Then hold select to get to the advanced screen
Okay. Will do that soon then. Testing on original hardware now (well, PS2, since my Ps1 isnāt hooked up).
Iād assume that ps2 is close enough since it isnāt software emulation, and Iām using the actual official disc for the game.
Legends 2, not Tron Bonne.
Oops. Same result though
Interesting, thanks.
Nice D (͔° ĶŹ ͔°)
Hard to see over video but doesnāt look like thereās any problems.
I think I see what the problem is.
I saw you were using a dualshock 4, so I plugged mine in. It indeed works WAY better with that controller, though still not absolutely perfect (i have a memory of the game having analog issue even on ps3, which I also need to confirm, but could easily be explained by stick drift)
Because the problem is diagonals. i think the game is expecting inputs at closer to the edges of the circumference than the range many analog sticks actually support.
GiliKit
Dualshock 4
The lit up square in each pic is how far to the north-east the stick can reach.
Oh⦠you can also read the coordinates at the bottom. Thatās probably easier than finding the slightly brighter dot lol.
When the analog stick is only pushed partway in Legends 2, it activates the walking animation which is tied to 8-directions-digital. Thatās why spinning the stick will result in Mega Man abruptly stopping, because he is tranitioning into a walk cycle and digital direction.
the game doesnt have analog movement, its just translating the analog into 8 way
and spoofing holding the walk button until you pass a threshold on the stick
No, it definitely feels like actual analog control.
At non-walking speeds you can make very precise changes in direction.
The game does tend to snap to 8 directions but it doesnāt HAVE to, unless you are walking.
oh weird you're right, walking is definitely 8 way only
i still tries to snap to the 45s a lot but you can do proper curves
So running is analog but walking is 8-way?
Yep
Probably a weird consequence of being on the same engine as the first game, which ONLY had digital input control.
Gran Turismo 2 PAL freezes in GT mode ā>gran turismo league ā> selecting a race. On stable version no problem
Freeze here
Ok, thanks
20260113/20260118 seem okay, I'm checking the other recent unstable versions.
The regression appeared when a fix on DMA empty sector read was introduced on build 20260123. @ivory verge
Gran Turismo 2 (Europe) (Disc 2) (Gran Turismo Mode)
Choose you language - Start Game - Try to go on the menu and navigate to Go Race.
It should crash after 2-3 attempts.

@dark mountain @dusk berry thanks ! I'll check it out in the next few days. Worst case scenario, we'll have to live without mirumiru š
for now version without change for MiruMiru
If that's a gulikit elves 2 pro (I say pro because of the colour scheme), I suspect that the issue might be related to the circularity being too good - one of its selling points is the drift free sticks. So, I'm not sure what it's like with ps1 or ps2 controllers, but ps3 controllers have very "square" circularity, ie diagonals go way past the edge of the circle to basically a corner of a square. Some games even expect these excessive values, including some big ones like Ratchet and Clank. Anyway, you could test if this is the issue by using the 150% stick sensitivity setting that your controller has. According to the manual, you hold the little gear button and press the l3 or r3 button depending on what stick you want to change. One vibration indicates 50% sensitivity mode, two vibrations is 100% and three vibrations is 150%
@dark mountain @dusk berry please try this
ok, 5 minutes please
No problem
Its fine now
thanks for testing !
Fine for me too on the SS1.
thanks!
please try MiruMiru too š
To be honest, it's costing me too much of my health. These fixes are causing too much stress.
I need a break
please test more this core
with other games
I know, only too well, that's already so much from you to fix these games.
OKay, I will take some time later tonight, thanks you so much for what you have done.
Thank you all for your support and help
where I can get it?
@dark mountain where is the iso?

I can't help for providing any ISO, as it violates all rules here, and I will test the MiruMiru demos later today.
There are also installed on my machines.
ok
Sorry
lol, no worries
mirumiru vol 1 , disc 2
thank You!
yes correct, only vids
Ok. At first, not problems with the vĆdeos
I will check the other MiruMiru discs too.
Ok
please dont feel bad, remember rama is still working on xstation after 5+ years, PSX is the wild west š
There haven't been updates on the github for almost 3 years, is it really being worked on? š¤Æ
xstation? yeah there was a beta late last year
10 minutes
It's a simulation game, like Theme Park.
Fully in Japanese.
I just like the name of the game and for joking around.
with psx_gt2 test core?
The game doesnt load
On stable core, it loads
on 26th inestable, it doesnt load
The MiruMiru demo discs are working on psx_gt2 test core.
I will check BurgerBurger too.
burger doesnt load
I can confirm, I'm checking all the previous builds.
it's broken with 20260113 , fix for Parodius
works with turbo low
must be very sensitive
So, we have a workaround.
It always seemed that 90% of the open github issues came from the CD subsystem and now this seems to be kind of proven.
Yes, it's very complex, and there are many games that do strange things.
Seems to be working perfectly now with it set to 150%! Thanks!
burger burger is very timing sensitive , works with limit max cd speed or cd fast seek, cd speed x1, turbo low option. Unfortunately, I don't think I can fix it in this situation š
It's not that I've given up. I'll check a few more things. In a few days, I'll make a pull request to fix the regression in GT2. Please continue testing. Thanks!
I suppose the endgame would be to implement low level CD-ROM controller. Have any emulator or ODE taken that step?
To a certain degree; PC Engine implements the SCSI processor in FPGA, but the way it's implemented in reality (i.e. real hardware) is a bit non-SCSI ish, so it's not a 100% match
A couple of weird edge cases don't behave as you might expect, and may not be implemented 100% identically
Glad it helped. Good to know my controller hyperfixation autism is kicking in too š
You mean ādeep worldly knowledgeā
This is what Rama has been working on for the past few years with MStation; a drop-in PSX cd-drive replacement
How does that work? I thought that the way the PSX is set up, any ODE would require soldering but apparently this doesn't.
@dark mountain @dusk berry please try this (Burger Burger)
Crime Crackers , Jikkyo 95, Parodius , Burger Burger , GT2, mirumiru works fine for me
thanks!
5 minutes, master chief
I tested: crackers, jikkyo 95 (rev 1), burger, gt2 and mirumiru. I did a fast play and i dont see problems
Many thanks!
Is This last build has the mgs codec fix?
No sorry
Ok
Fine for me too.
I can't take for today more than 2-3 mins for testing each title.
But I didn't see anything out of order here.
thanks Z ā¤ļø
Would emulating the CD drive at a low level be feasible? Would there be space for that if it was?
We need the dumps of the chips on the CD controller in order to RE them.
When I helped Stenzek on beta testing during the beginning of Duckstation years ago, these dumps weren't done at all.
I don't know if the situation changed since then.
Even before talking about space.
Oh, interesting. I am going to assume that dumping these is a lot more complex than older chips
Thanks dude
Playstation is really, really, really cool.
I am having an issue with the settings for this core. I can view and play games and such when using VGA...but when i try to use hdmi i get no signal. is there a fix for this?
edit: and hdmi works fine on other cores like nes snes n64 and such
Presumably, it would entail unplugging the power and ribbon cables, replacing the CD drive with the ODE, then reattaching the cables.
Yes, but there was some reason why previous odes couldn't do that.
Googling this up apparently the drive controller is built in to the motherboard. I guess emulating low level means you can use the existing drive controller?
@dull wedge works now, should behave as the documentation states
Amazing
Have you tried with the Spyro mod as well, that's how you know a 100%
I have the normal exception handler re-arm the breakpoints, it cycles 2 of em in a row
I could ask someone to test I suppose if the update is online
No, didn't test that. Maybe someone else wants to do that. To be honest, i'm not familiar enough with the game to even understand what is supposed to happen.
I get no video with that rbf. Only audio and a white screeen
strange, would guess either upload broke, download broke or your mister needs a new boot
works fine for me
But I can't check Spyro because I have no idea what it's about š
i'm not 100% sure myself i think its this thing?
https://gbatemp.net/threads/i-tricked-the-ps1-hardware-to-ignore-spyro-3s-uncrackable-security.678736/
I went on a journey to bring the legendary double-jump glitch from Spyro 2: Riptoās Rage back into Spyro 3: Year of the Dragon. Not on an emulator. On real PlayStation 1 hardware first.
Hereās the problem.
Spyro 3 did not merely remove the glitch. It actively fights you if you try to restore...
i dont see like, an actual patch file just a really long code so idk
one could make a cheat file with it, but i think it's better if @dull wedge provides a patch file, checksum of the base .bin and instructions on what to do.
This will make sure we are not debugging something completly different, because the patched .bin can be verified with Duckstation.
Whomever I need to provide a link for, I can
If one knows how to do the double jump in Spyro 2, my Spyro 3 patch adds that back in, by leveraging the cop0 debug options to stay undetectable
It's a ppf
I'll ask try to ask someone that has direct access to it as well to test it. If anyone else is willing, I don't mind sharing in dm's either to save some hassle. But for strict legal reasons here, I provide a ppf only
Can confirm the Spyro 3 double-jump exploit works on this
Good work, Robert š¤
That's great! Now people should be able to double jump without the game pestering the player, and the method can even be used to bypass other things as well.
It's cool having contributed to this by providing the testing material, the core passing the test is not insignificant, most emulators absolutely fail it by either not understanding memory mirrors and ending on a black screen, or landing on a red one by failing the cop0 execution watchpoint/breakpoint
This is what I love about MiSTer cores, even when they seem complete, people keep finding ways to make it just a little more accurate
MiSTer wins again! 
Thanks, I used it on PS1 with xstation works very well.
Thank you very much, it's now in the main branch and will be in all upcoming builds.
I'll send you the invoice later for the Super Station One š
Dude, Robert gave us the PSX core for free. He aināt paying for no oneās Super Station One. I know youāre joking but this one doesnāt sit right.
Unicorn is fine. They have been working with Robert on this latest fix. Appreciate you looking out for the devs.
Hi, I would be very grateful for your help in testing this core #test-builds message I would like to close this topic. I no longer feel up to working on further improvements to the PSX core.I feel too much pressure. I have tested over 100 games, including boot, intro, and gameplay, including sensitive games such as Parodius, Crime Crackers, JikkyÅ 95, Burger Burger, Ogre Battle, and others. Unfortunately, the days when every change was tested by about 200 people are long gone (which is not surprising), and I am unable to detect all the bugs on my own. If more regressions appear, I will revert to the original working code without these changes. Please test your favorite games and let me know. Thank you for your help.
I could check more these changes too, but I'm not at home until several days.
I presume the latest unstable doesn't have kuba's fixes yet?
Nope.
Only the recent changes from Robert.
For clarity: I contributed by creating the testing program used during development.
I do not own a MiSTer FPGA yet, this contribution was made for the community.
The invoice comment was clearly a joke.
Thank you for the contributionās. I appreciate it and know many others do as well.
You're most welcome ^^
Im playing resident evil 3 usa to complete and i dont see problems
Thanks ā¤ļø
Merci š
I usually have my MiSTer connected to my CRT, but now I“m running it on my LCD TV and I think the aspect ratio with fixed blanks are to narrow horizontally. Shouldnt the aspect ratio be corrected with fixed blanks?
The Sony logo in bios boot is squished
The bios diamond should be a little squished iirc, vertical crop on 224/270 will push the image back out to 4:3. PS1 is such an awkward console as each resolution will look different depending on the settings used, fixed blacks on with 224 vertical crop is the best middle ground imho.
thanks but I“m comparing the image to a real CRT and the logo is not squished on a CRT. Also button icons are not round in MotorHead
I've seen pictures of CRT's with square diamond and squished diamond. A setting that will give round icons in motorhead could give non round assets in other games, it all depends on the resolution.
Mednafen and Duckstation have squished diamond at default settings last time I checked too.
The aspect ration should be corrected to how it should look on a CRT. If you are comparing how mednafen and duchstation look on a pc monitor is not representative of how it should look. Unless those emulators have corrected for the aspect ratio.
It could be though that some games were corrected to a CRT when they developed the game and then today on flat screens it looks squizhed.
But I thought the fixed Blanks corrected the aspect ratio to how it should look.
By disabling fixed HBlanks it looks more correct but slightly to wide
the Bios screen should't look squished. It's 640x480i, which is exact 4:3.
My guess is that there is horizontal padding on some resolutions and if you don't account for it then you get an image that is slightly too wide on others, happy to be corrected on that.
So what is the reasoning for all these emulation options adding horizontal padding? Genuinely curious.
That picture is not representative of how the logo looks on a CRT, since the geometry is not correctly setup. It has black bars both left and right. And still it looks wider than on my MiSTer
I checked my LCD TV if maybe I had the wrong setting, but its on Gaming mode so shouldnt scale anything wrong
Just a friendly reminder that if you suspect there is an issue with the core, please make sure an issue is on GitHub for it (and create an issue if one does not exist)
Discord is ephemeral
yes, I just wanted to get people that also are used to CRTs to chime in if they also noticed it
What does that word mean? 
Like ātemporaryā or ānot lastingā
Easy for stuff to get lost in a channel
Thank you. Today I learned something.
It's something I have seen been discussesd for many, many years when it comes to emulation of the PS1. I think it's so that all resolutions fit within a fixed 4:3 aspect ratio, the bios has horizontal padding that normally would be pushed into in overscan but is now visible in that fixed resolution space. It's ether that or you have the aspect ratio for other resolutions potentially be outside of 4:3 as you noticed.
For reference here is how the logo looks on my LCD-TV, with fixed Blanks ON
Want me to check mine? Although I use integer scaling so I have no black bars either side. (If I donāt use the fixed blank modes)
yes, since a CRT is not a pixel display what ever resolution you send it will stretch to the 4:3 aspect ratio of the display (as long as the signal is compatible). So if you want to have the true experience the emulated result must stretch/shrink to a 4:3 container.
What would be ideal is if the fixed blanks setting and vertical crop settings could be separately applied for 240p and 480i instead of the settings working on both.
If you could just to rule out I have something wrong with my TV or mister settings
Sure il need a few mins. Il do it without the fixed blank modes enabled
analogue output bypasses the scaler so it doesnt matter the scaling settings in the core. Never mind I misunderstood first.
I always used to have the vblank modes enabled thinking it would stop the internal resolution changing.
But the other day I tested without the blank modes enabled and got a full screen picture. And I hardly had any internal resolution changes
But thatās probably down to the integer scaling I have enabled. Iām not sure. Iām an absolute noob when it comes to all this resolution stuff
yes to my eye the aspect ratio is better without fixed Blanks
use with fixed blanks because thats what I used in my pic
Okay dokey. Il enable both when I boot up my mister soon
this is according to the readme:
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.
so it is recommended to have them on on an LCD TV
So my tv is a 4k 65inch qled + mini led. I have 1440p video mode on mister with hdr,vrr and integer scaling
Just loading up psx core now
Resolution is 1952x1430p for the psx core. Just taking photo now
Fixed horizontal Vblank gives you a 704x480i though.
I enable both V and H Blanks
It does seem slightly wider/stretched if I disable fixed blank
oh, lol! Thats not 4:3 aspect ratio š
Vblank fixed only gives you a 640x480i.
so are you saying you shouldnt use both H & V Blanks at once?
Thatās it without the v and h blank enabled
But from my eyes. It seems like when I have fixed h blank disabled. The text is ever so slightly wider
please take a shot with the Aspect ratio set to "Original" in the Video settings
Maybe stretched?
also if you can take a picture on the Sony logo
Aspect ratio is original
Iām guessing you want me to disable integer scaling?
how is it original if you have 16:9 aspect ratio?
With integer scaling?
No, I want you to have integer scaling and fixed H & V Blanks
This emulates a physical 4:3 screen (Fixed VBlank on, Fixed HBlack off)
Then yeah
looks good to me
that looks correct to my eye and wider than on my pic
The Mister doesn't allow free form scaling, it's much easier to set this with an external scaler like the Tink.
yeah, maybe this is not solvable with current scaling options in MiSTer.
why is your image stretched?
Both blanks enabled, aspect ratio normal
Only thing I can think of is integer scaling
The psx core for me is outputting 1952p x 1440p
If it isnāt the video scaling mode I use, then I dont know sorry
Its just it doesnt look correct in your pictures. It looks like the image is stretched wide
If I use the full screen mode. I get a resolution of 2560x1440p
The PSX core doesn't do a 4:3 auto correction
Just noticed if I use the widescreen hack 3:2 mode, it looks nice
Well, I will go back to my CRT in a week so will not have to deal with it. But not sure if I should raise an issue on github
I just booted Street Fighter Alpha 2 and it looks correct with the same settings.
For an integer scale i have to enabel 1:1 Square Pixel via Tink for the aspect ratio correction, then it looks fine too.
Hopefully woozle will have a morph board for the MiSTer soon and it would fix this as well as deinterlacing
If you don't raise a ticket I might, think a seperate blanks option for both 480i and 240p would be a potential solution, no harm in asking.
Again, Fixed VBlank only
Fixed HBlank works now too, with 1:1 Square Pixels enabled.
Of course for this Bios screen it just adds a litte black border left/right, no squishing.
Does my image really look stretched?
. This one
It's horizontally stretched. 1920x1440 would be 4:3
Oh right
Reckon if I drop my video mode to 1080p. Would that solve it?
(Absolute noob with scaling and resolutions I am)
it shouldnt matter if you have integer scaleing on
No, not really. Try video mode 12 in the mister.ini =1920x1440@60
But i don't know how the internal mister scaler will scale it on your TV.
Might look different
Video mode 12? Ok il try that now
Whatever now solves this stretching mode il be happy. I canāt unsee it now
anyways, thanks guys for checking! Not sure I will raise an issue since not sure how to articulate this and if its even an "issue" or just the way PSX resolutions work on modern fixed pixel displays
Right set it to 12
1080p =1440x1080p, 2160p = 2880x2160p. This is what you need to mimic a physical 4:3 screen from back then. 1920x1440 work fine on displays that support this.
Still too wide

Try vscale_mode=5 (or maybe 1 or 4)
You trying the double jump patch?
No. It just got pointed out to me earlier I have a stretched image
My v scale mode was on 4
Il try 5
(I picked 4 before as it said good for 4k displays)
Playing stretched is a crime in some places
I didnāt mean too š
No worries
I speak from experience, I had a guy harras me and my entire family because of it
Long and strange story, in short, a weirdo was stalking me
I wonder if your tv does some zooming or something. Can you confirm you have these settings
I didnāt have v integer
Do it
Lol
Still too wide. Can you post your video settings
I have video mode 12, v scale 5
Let me check what I have in my ini file
Iāve checked my tvs display settings. Itās been set to 16:9.
Yes so is mine
These are my settings
That looks ācorrectā but squished compared to a CRT. But thatās how it looks on my LCD TV
Thatās if I set my tv to manually display it as 4:3
Huh, maybe thatās the trick on your TV. Itās weird because on mine I have it on 16:9
I honestly do not know. Just going to try v scale 0
Woah
Hold the phone
Thatās with v scale mode 0
You want 1
That finally looks somewhat not stretched
For accuracy
1? I thought integer scaling would be better overall
As video mode 4 has a little text saying (good for 4k displays)
Il have to take a break for a bit, but il be back soon and try video scale 1
As long as your TV OSD shows 1920x1440 it should be ok (which is exactly 4:3), but the vscale settings influences the output of course.
You canāt force both vertical and horizontal integer scaling and have correct PAR, except when the original image has 1:1, 2:1 or similar PAR. Only forcing vertical can work nicely.
Was just testing video mode 14 again. But with v scale set to 1
Iām guessing the thumbs up means it looks correct?
Looks good for me š
(I think all of this is just proving how bad my eyesight is and my brain. And thereās me attempting to build a server to backup all my 4k blu rays)
Iām better off sticking to dvds
1 is integer scaling. 0 is scaled to screen height
Right, ok
Now load up the 240p test suite - test pattern -> linearity. š
(I cant tell if this is a joke or you want me to actually do it xD)
No, it's a CD Image for the PSX. A suite for screen calibration
I hope itās a perfect circle
Or passes the test
Uh oh
Iām guessing thatās fine?
Yall are making me go down a rabbit hole
Looks good
Yeah. Thank you for all your help. Seems like the plan is to leave it on v scale 1
For the PSX, maybe. But integer resolution scaling has some advantages too. Especially when you want to achieve nearly a fullscreen for some TATE mode Arcade games.
The Japan stuff arrived in preparation of the Superstation
Let's see if I can get that baby to work
The TV is waiting
Nice! 
One thing though: This video mode 14 is just horizontal pixel repetition, because a real 2560x1440p resolution exceeds the Mister HDMI bandwith limit. It's actually a 1280x1440p resolution where 1280 is doubled. Fine if you don't use CRT masks. They look very coarsed in that resolution.
hi all - is there a known issue with the psx core and Parasite Eve 2? after the boss in ||Dryfield|| i get stuck on a white screen
there are some issues with parasite eve 2, but I canāt remember if that is one. Do you have a save state that others can test with?
i did make a save state at the beginning of the cutscene, yes. where is it on the SD card? i've never shared a save state
should be in /media/fat/savestates
(/media/fat may be the root of your SD card depending on what OS your mounting it on)
try [this one](#test-builds message) if you donāt mind
Yāall got busy in here
no dice unfortunately, but thanks for the tip
All I know is that Spyro looked wrong when not set to wide Integer Scaling based on the image on earth at boot only looking round on that setting
... Over HDMI
for posterity: was able to get past the freeze using duck station
Parasite Eve 2 is like the end boss of testing compatibillity. Emulators often can't fully emulate it properly, crashes happening even on a real console with a chip. Savegame corruption (actually made a patch/cheat for that so it doesn't happen anymore)
I finished parasite eve 2 on the core last year without issues except that I had to suffer through parasite eve 2
on the topic of parasite eve, I'm playing 1 right now, and can't seem to get through the disc swap
I have both discs in a single folder, all I should have to do is load the second disc from the menu when on the "insert disc 2" screen?
I've also tried toggling open/close the tray in the menu, doesn't seem to trigger anything
nevermind -- was the cue file
hm... i completed PE2 a while back but i can't remember if it was on the core or real hardware
I think @sinful bloom played pe1 recently for Christmas and should know if there were any issues. Sorry if I remember the wrong guy.
#1046940919607345272 message it's resolved
sorry, I dropped the game and didn't make to disc2
Sorry I'm still learning how to read. š
I need to do another playthrough and NOT do automatics
that class of weapons is a trap
You should!
I like pistols best.
I was literally stuck beating bosses with the police baton
There was something when you gather like 200 junk from crows in central park you can get the best weapon in the game.
There is also a dungeon that's exclusive to ng+ and it's really fun to make the ultimate weapon with all of the best abilities.
So everyone who had a PS1 in the 90s, how did it feel to be on the winning team?
I had no idea there was a winning team
I didn't even know N64 and Saturn were a thing
When youāre so far ahead of everyone, it can sometimes feel lonely
The only time I was ever on the winning team, until PS4 gen 
I was always on the winning team because what I like is winning
Master system, Mega Drive, PS1, Dreamcast, Xbox, PS3, PS4, XSX⦠my primary consoles during each gen 
I consistently picked badly
mega drive was the winning team - donāt let anyone else tell you it wasnāt
I remember playing ff7 and ff8 on the psx and believing this series could never go bad.
around the time the n64/psx came out I really got into pc gaming, especially the backlog of games I had missed out on
spent a lot of time in #oldwarez, lol
Cheers mate, il probably set it back to 1280x1440p then. Much appreciated
All I thought of was "Wow video games!"
One of the very first psx games I ever played was hogs of war or Frontschweine, as we call it. Didn't play it since then and been meaning to ever since. 
I was poor. 
||I am poor. š ||
Iirc the gameplay was basically valkyria chronicles before valkyria chronicles.
Itās a good game
With Rik Mayall!
My favorite character was ligma.

Two worlds
Some games use the CD pause command in different ways. Parasite Eve II pauses the CD very early, while the disc is still getting ready, and expects the pause to be accepted so loading can stop cleanly. Duke Nukem and the MiruMiru demo pause slightly later and expect the CD to refuse the pause until at least a small piece of data has been read, otherwise music or data breaks.
I remembered today that Robert fixed it three years ago. https://github.com/MiSTer-devel/PSX_MiSTer/commit/6eb4bc7f087d138842a1e92479401ba86003fefa
I also made a change in the pause, which is a prerequisite for the proper functioning of Duke Nukem TM (music) and MiruMiru. There is no other workaround for this problem. This broke the only game, Parasite Eve II.
Now these two cases are covered and it should be fine.
Interesting, thank you for looking into it. I was able to get past the screen on duckstation then transfer back to mister, but I actually encountered another freeze after the prompt to insert disc 2
So I can try both those cases in a few hours
I got one after I got a N64 actually...
Disc 2 , works fine
Games were so cheap, I got weird shit just to try it out.
āYo, this red robot with long blonde hair looks hot! Let me try this out.ā And then I became a lifelong fan of the Mega Man franchise.
I had Tomba, Gex 1-3, Crash 1-3, Crash Team Racing, Spyro 1-3, Armored Core, Spider-Man 1&2, Wing Commander 3, Colony Wars, Final Fantasy VII and VIII (borrowed IX), Rock em Sock em Robots, Gundam Battle Assault 1-2, Mega Man 8, Mega Man Legends 1-2, Mega Man X4-6, Guardianās Crusade, Toy Story 2, Tekken 3, Medieval, Bubsy 3D, a ton of demo discs, and more that I canāt remember at the moment.

#Disable memory card corruption checksum
D0032B3E 1062
80032B3E 1000
So, usually when you save the game with cheats on, there is a chance it will corrupt your save for the next boot. Either due to an overflow that the memory reads as a corruption, or as some kind of anti-tamper measurement. However, this code will completely disable it
I am not clear on how the chat system works (I only tried it once and it just... didn't work for me) but could this itself be added as a cheat?
It depends, this is basic gameshark format. Might need to be formated a little different for different cheat systems.
01 00 00 00 3E 2B 03 80 62 10 00 00 00 10 00 00
Is what it should look like for the PSX core according to chatgpt
lol those games arenāt good
this is going to be a meme where you try to put as much time as you can before the THEY'RE GREAT! follow up
Groo the Wanderer did this gag decades ago, Robby!
THEYāRE GREAT
this didn't work for me on the stock core or the one you linked. at the end of Disc 1 i get the insert disc 2 screen. after loading disc 2, I get the intro text crawl, and then a black screen
oh, interesting. disc 2 just doesn't load at all for me š¤
ok, disc 2 was a bad rom so that was just on my end. your fix worked for that boss fight. thank you š š»

Thanks for checking!
shouldn't kuba really be yellow at this point
unless you just prefer the technomancer tag
Kuba yellow wen
Maybe we need a colour to distinguish between the single sdram peasants and the dual sdram elites
I think you got them wrong way round
No it's correct. I double checked it twice
You dual rammers have been brainwashed by "the man" brosef
You think you always need more and more
Just stop
Close your eyes
Breathe
And accept
Oh yeah, this Saturn game? Totally runs one frame faster with dual ram so instead of 12 fps itās 13. Wow, can you imagine not having dual ram?
Wow, this Saturn game, that totally looks and plays better on the PS1, doesnāt have a flickering pixel with dual ram. Good investment am I right?
Close both our eyes? How about you install both your ram sticks instead. 
Yes you are right. It is a good investment. Happy you finally see the light, brother. š«
Can we have a third colour for those who got dual sdram "not to have an empty slot"? š
No. Don't be ashamed of your dual ram superiority.
I know a new poll
Chad dual ram vs virgin single ram? 
Hmmm... your comments have shaken my belief in single ram superiority to its very core!!!
I find myself once again on the precipice
Of a purchase
This should help you: #general-banter message
Luckily though I have a self imposed protection method that triggers whenever I consider altering the MiSTer in any way
I call it...
Extreme lazyness!
I got my mister prebuild since I'm so lazy. But it was with very cheap parts, so the fan of course died after a few months.
Just wait until yours dies to "beef it up" as my favorite dev keeps saying.
Seriously tho, the actual reason I dont have dual ram is some vague recollection that somebody somewhere at some time said something about the digital io board not playing nice with some analogue signals sync wise or something.
I use an external scaler and an oled tv anyway. No space for an extra crt.
Also crts are tiny.
This comment might have enraged me were it not for the fact that I happen to own a pvm-4300, the largest, rarest crt ever manufactured. With a 43 inch viewable screen bringing any 4:3 content beyond the horizon of even a 65 inch oled.
I did the math, my 16:9 tv has 63" used when displaying 4:3 content.
43" is just pathetically small.
I cant keep up this charade
My crt is only 21 inches
Im sorry
Anywhoo I also have a big oled
But the MiSTer is stuck in an arcade cab thing
I think I need...
ANOTHER MiSTer!!
This is true. And do you know what this second mister needs? Dual ram. 
You can never have too many sticks of ram
||Unless you have more than two, at which point you need to buy more MiSTers||
I have two sdrams in every Mister š
They don't even need to be plugged in, just rattle around in the case. 
Well...
Oh donāt give me the dots. I havenāt changed anything apart from going with video mode 12

Iām going back to building Lego
All I changed from the other day was trying out video mode 12 instead of 14
Do you wish to see my space ships?
I wish to cry (but for sure!)
I hope this brings you pleasure. Legos are so much fun.
yes, you changed from a 16:9 AR to a 4:3. your TV is probably deciding it needs to stretch 4:3
Probably. A lot of TVs are that stupid when you run a 4:3 resolution on it.
Right. Iāve gone back to video mode 14. This worked fine the other day
Video Mode 14 will work better in that regard. But as i mentioned earlier this is horizontal pixel repepition.
It's actually 1280x1440p then.
Right we are back. Itās not stretched anymore
They look amazing. Iām waiting for my alternative brick Orthanc tower to be delivered
Hope it's better than the lego baradur tower. š that one is very underwhelming for 500$
With CRT masks probably not so much.
Yeah thatās what I wanted to try 12 like you suggested. But for some reason my tv does not like it
Which brand?
Does it have various options for the aspect ratio? Like 16:9, 4:3 or "Original" or something?
See I checked this the other day when I was talking to WickaWacka about it.
I have 16:9 and 4:3 options. (Aswell as various other sort of zooms)
But nothing original
And 4:3 didn't work? It just stretches the 1920x1440p resolution?
If I set it to 4:3 manually it works. But wouldnāt I have to change it for every core?
Well since it's a 16:9 TV you have to do it manually. Only an external scaler like the Tink would output it correctly, 4:3 centered within the 16:9 resolution. Well some PC monitors can do it automatically.
Right I see, interesting
Iām just unsure if it would be worth it buying a retro tink just for my mister. But thank you for explaining
It's a dream combo for many reasons, but very expensive.
Well that the top one
The CE version doesn't cost that much, right.
Oh Iām checking a franchise in the UK called CeX
As Iād probably have to trade in my Atari jaguar and mega sg for credit.
If you don't need full CRT filters it's ok, just use the Mister directly.
Ok mate. I appreciate your advice. I do recall there was some mention in this discord of some sort of mister board for scaling stuff. If that ends up being a thing, I might wait for that
But until now il just keep with scanline medium filter
(Iām trying to keep this option in case my gpu dies)
just put the TV in 4:3 and run every core with video mode 12. they'll all output the same 1920x1440
Some cores might act different though iirc, when they have "fullscreen" or "original" options for the aspect.
sure, but it won't require fiddling with the TV too much. guy has been playing cores stretched to 16:9 forever, it's probably ok to just put the TV in the right mode and move on
Now Iām starting to wonder if I have the right settings 
or just use 14, who cares if it is pixel repeat
Yeah, Iām slightly disappointed in that
Canāt believe I did that
it certainly doesn't necessitate going out and buying a tink to fix this
As i said. CRT mask fans. But yes, if you don't need it the pixel repetition is just fine.
Il just leave it on 14 for now. Cheers you 2 for your tips and whatnot. I appreciate all advice
Good news is. It means Iāve got to replay the Resident Evil games without scaling
The Tink has other perks for Mister. Proper HDR with correct colors, auto-crop, auto decimate, proper VRR options, MPRT BFI etc.
Youāre gonna be shocked at Jill before she was a sandwich
She's still a snack. 
Was curious if anyone has been able to get Biohazard Gun Survivor working with a guncon over SNAC? I know only the Japanese version has guncon support and everything works except i can't fire the pistol. Apparently you're supposed to be able to shoot at the screen to fire the gun and then you shoot away from the screen to move forward, but no matter where i point the guncon my character just moves
the gun works fine when calibrating it in the menu so I'm not really sure what I'm missing š
does it work for other GC games? if yes maybe you could try tweaking brightness.that game was really dark
every other gc game works flawless as far as i can tell
and like i said it doesn't seem like the calibration is off. I know there's a guncon patch for the US version so ig i could try that
yes try that, that should work
I have 8 ||in an old workstation desktop that runs in quad-channel mode||
PAL version does as well
Hello thank you, we are pal? I am please. Hold hands?
I did figure it out lol, had to max the contrast in my CRT's menu
On the topic of guncon 1 and snac Iām having trouble getting time crisis 1 to work right.
Time crisis will get to certain points where there is flashing or the screen is dark and all the sudden I canāt hit anything no matter how hard I try, unless I just spam bullets and pray. CRT brightness is max, and my guncon sync line is hooked into the green component input in the back of my crt.
Other games seem to have no issue
have you tried plugging the guncon sync line into the snac adapter?
Gun bad, use bow arrow?
alright, gimme some of the worst performing PS1 games
Hanabi Fantast
I can already happily say that 2XCPU core gives really good performance boost to Descent and Duke Nukem - Total Meltdown
I suspect the photo diodes are starting to go bad in these guns.
Not familiar with a 2XCPU core. Is it similar to the 80hz and Turbo cores for N64?
Hmm. I can see it in the pinned messages, so Iāll download and try it out today.
I doubt it will make the load times any faster in Xenogears, unfortunately.
it won't
in fact I think it will make it worse
I had characters getting stuck in level geometry on duckstation
what does duckstation have to do with MiSTer?
I had a few enhancements turned on which messed up the game, ages before I had MiSTer and I imagine boosting CPU is gonna wreck it
-# not that I am going to commit to incremental 1.5 hour binge sessions of Xenogears on MiSTer's 2XCPU core spread between 4 hours of blackout to find out
Well, guess it will be up to me then, because I have a xenogears playthrough in progress
nice game š„
quake2 runs well to start but runs incredible on 2x core
You can already boost the CD read speeds in the standard PSX core
Certainly tempting.... I played need for speed III for the first time in 25 years and the PSX X2 core made it so much enjoyable (almost as I remember it with PC + Voodo graphics)
Game can crash randomly if you set it to 6x speed, which is the first speed at which you can notice any change at all in load times. Crashes immediately if you set it to x8 and load anything.
Try with limit max cd speed
Perhaps, I hope not. Do you know the replacement part for that?
In any case, I tried it on a different crt in a different room and it worked fine. So thatās a relief that it had something to do with my specific set up or just the tv even.
last person fixed Biohazard by tweaking contrast
That one worked fine for me, in fact everything I tested but the first time crisis worked, even the semi sequel on ps1
its probably a bit of crts getting dimmer, a bit of lenses yellowing, a bit of photo diodes aging out
possibly a bit of those specific sections of time crisis not being a great idea in the first place
Admittedly while itās nothing I can see that crt I had trouble with is beginning to fade. Mild geometry issues are starting to crop up
I only really noticed going through the service menu
there are sometimes capacitors involved too , in the lightgun i mean
there's just a lot to go wrong and very little tolerance
i can report if you use like, a modern lightgun that uses IR tracking, that section plays much better
and you could technically do that whilst still using a crt if you wanted
Thatās interesting, I just have the three guncons. I can at least confirm that guncon3 has no issues at all on crt or lcd
I am Japanese apparently
I'm fine with playing these depressing ass games. Better than the majority of slop that gets released today
That was in context to Nintendo 64 not doing so hot in comparison, so would you say the same to that?
I also like to feel bad, and feel things lol
would it be fair to say he was a vile man who hated games
Iwata was loved, Yamauchi was feared
That's why they must have released the Switch 2. That thing has made me seriously depressed. š¤£
People actually feared how much they loved Iwata, so he kinda played both sides.
There is a few softlocks that can occur due to the game loading things too fast. Like Deus larva fight shifting camera, some cutscenes with fast text patch etc. I don't know if these occur on MiSTer but they will occur on a PS2 with fast disk but never on a real PS1. (the deus fight)
Would be nice to confirm
Duke nukem time to kill and land of the babes. There is even a setting in game to increase the game speed
Even with turbo set to max aswell as 2xcpu. The framerate fluctuates so much it feels horrible
oh yeah, I played those, it's heinous and you'd rather play Zero Hour on corncore instead
not related to boosting performance but I just wanna know
anyone here actually played and completed Alien Resurrection on MiSTer?
is it broken here too?
the game is not "impossibly hard", it gets broken when you emulate it
and also what happens if you switch discs and use a bootstrap cheat
There was only one bug reported a few years ago, concerning spu. It has been fixed. I spent several hours playing the game and there were no problems.
The backgrounds in SpongeBob SuperSponge don't look right :(
this is a known issue, it seems https://github.com/MiSTer-devel/PSX_MiSTer/issues/310
My apologies for missing that then
I actually went back to that first crt and tried playing it through composite/svideo and it worked fine.
So it was something about the way either my tv or my ini file was handling the component output
I have a dumb question, im on the psx core and my virtual memory card is down to its last slot, what do I do?
if you put every game disc image in itās own folder, the core will generate virtual cards on a per-game basis
multi-disc games should have all the images in the same folder
ill go correct this problem now
does the ps1 bios have memory card management? I forget
yea it does i think
Iām sure you can copy save files from your main memory card somehow and transfer them to new cards for each game you need
does the core have an option in the osd to load specific memory cards for slot 1 and slot 2? I think it does
Yea it does
for each game folder does it have to match the iso name or can it be w/e?
does not have to match the iso names
You can also use chatgpt to make a bat script to transfer all your files to their own folders with same name
That's easiest, that's all I did
wow, thanks!
after youāve added the folders, I think all youād need to do is launch the games you have saves for to create a new memory card for it. Then just launch the core into the bios and load your main card in slot 1 and then the new game card in slot 2. Transfer your save from card 1 over to card 2 and then repeat for each gameā¦a bit tedious but shouldnāt be too bad? Maybe thereās an easier way, but Iām not sure
I basically done the same, but I used save states
Made a savestate. Moved the game to the correct folder, then loaded the savestate
oh yeah that works too
another question but im looking for oem psx controllers, is non dualshock acceptable or do a ton of games use it? All I remember from being a kid was the RE 2 dualshock edition..can't recall if MGS did
well i guess that's more suited for the controller channel but oh well
there's only fringe cases like Ape Escape that requires it
and that's the only one I know
the rest of the library is playable with a dpad
ok
RE2 dualshock edition is played through either the dpad or left stick
MGS is fine with dpad and there's no precise stuff like in MGS2
okay, so there's RC Stunt Copter that requires dualshock
it's a very hardcore (and stupid, and spiteful) RC Copter sim that treats dualshock as an RC controller
and there's Tiger Woods PGA Tour for.. swings?
you can try playing Alien Resurrection on non-dualshock, sure
and you're going to suffer
TIL Ace Combat 2 and 3 require sticks, you can't pilot the planes without them
They don't require sticks, I played through both using the DPAD.
fine then
Maybe this interests anyone
I sometimes have people commision me for adding analog support to d-pad only games, so this is one of those projects
That looks sick. Gotta try it later.
I gotta say, this requires a very specific version of TR1 to patch that isn't listed as "v1.1" by Redump
Rev 1 didn't work
yup, works great, with a release that doesn't have 57 separate tracks and instead has everything combined into a single .bin
Yeah, it is V1.1
There were more revisions later I believe, but they just switched out demos I believe, no real fixes
Here's another QOL improvement. One of my favorites. I made multiple versions, but having the scph1001 bios and running one of the Kernel versions is safest
https://romhackplaza.org/romhacks/resident-evil-quick-turn-auto-aim-edition-playstation/
It fixed the flamethrower bug, + adds quick turn to the game, works with aiming too, just gotta press R2, optionally there is auto-aim that a friend of mine added ported from the later versions
I could probably add analog support too at a later point in time. Making that quick turn was brutal, I work in raw asm
Awesome
great stuff
oh i somehow didn't realize you were the same guy from the RE patch, did you have any luck with adding quickknife?
The official one, yes. If you are using the open source one that comes with the SuperStation, no, but you can replace that with the official one
Yes, you can manually load memory cards too, I have done that to manage saves from a singel card to copy them to multiple ones
Personally, I can't go back the stanard PSX controller. Even back when the DualShock was new and I only had it for a few months, the original controller felt like a way too light bootleg knockoff after using that. Also while there are only like, two games that require it, it's optionally supported in many games and I find the use of analod over a d-pad much better to play 3D games with
Medal of Honor and Underground, for example
Iāve been play testing analog mods for re1-3 made by backxdash on YouTube. You should get in touch with him.
I know him, he often credits me
Cool guy
Oh okay awesome, itād be great to have all those improvement features in one single hack one day for re 1-3
Not te RE1, but I have with RE3. Wouldn't be too different I suppose. My best RE mods are for RE3, emergency backup knife, danger mode power that vibrates controller in a heartbeat pulse, backup knife, a custom knife that steals enemy HP
nice does that re3 patch work on real hardware too?
Yes
I broke that game open for other modders, adding more space to it and disabling checksums specifically so it'd work on the real deal with added space
It is still superior to the PC version in many ways, more stable
If you're interested in RE mods specifically, I moderate the classic re modding discord with a bunch of cool modders
Can send ya an invite
A dream would be to run Resident Evil Randomizers on the core.
But I reckon that wouldnāt be possible. I like running RE3 og on PC with Biorand for randomised fun
yeah sure, have you got a link for your re3 patch too?
there are so many RE1 mods lol, i'm pretty sure one of them is that
maybe ultimate directors cut
Yep, I believe so. Also includes the text of blood on one of the walls
I have it on my mister
I canāt find any links that work for ultimate anymore but this does very similar https://www.romhacking.net/hacks/5837/
that one changes some rooms around and other stuff too
sorry dont click that it looks like all the links are busted
that one had the orginal music with uncut fmvs, and blood on the wall. The 2nd disc is cool too, it had battle mode and maze mode with all special fmvs
did someone do that?
I don't know how would anyone do that
both games use 2d backgrounds, and 3d models run around on top of that. They mask off areas that you can run behind to give depth.
it would be pretty cool to see
possibly it would all be too visually noisy with mdec encoding+240p
and they have different camera angles and they've expanded the mansion layout so you have to contrive a brick wall on the second floor
yeah it would be like making a whole new game really
not impossible but a huge project
RE 0 Demake is well done, but I think only a demo was created? I remember playing it, but I don't know if anyone worked on it after that.
I have the standard modders edition patch, people just add to it. However, most of my mods I released as codes too. Not sure what I still have, I think quick knife with hp steal and zombies being able to inflict virus
Ill send you a dm for the RE link, unless it is cool to post here
you can post patches here just not entire isos or anything
Burger Burger
peeeeeeeeens
No Burger no fun š
@mortal oracle McDonalds today, we have to help out with the Burgers.
I must point out one thing. Vigilante 8: 2nd Offense has the old problem again. By accidentally breaking Parasite Eve 2 when changing for pause, I fixed V8. It turns out that the 2023 fix for PE2 is problematic for this game. Now that I know where the real problem lies, I hope I can fix it. This is not a new regression; I simply restored the original functionality for PE2, thereby returning to the old bug for V8.
The comment left here already gave a hint, but it was too general https://github.com/MiSTer-devel/PSX_MiSTer/issues/296#issuecomment-2870197466
Of course, the old workaround works, CPU turbo or fast seek.
I just got done testing this so complain to me if you have trouble :p
HAW HAW HAW
fasted forward in the west
well you beat me most of the time lol
I hope I have resolved all critical issues. @chilly kraken thanks for testing!
So does this mean with this latest unstable both Vigilante and Parasite Eve 2 work?
with the one linked, yes
Yes, I always try to include the core with all previous fixes.
Okay, lemme accidentally find another game you broke
Jokes aside, great, I can resume my Parasite Eve binge
Nice. IIRC fixing one kept breaking the other so I was worried if it would not be possible to have both working at the same time
So are there any other known issues now other than some graphical corruption in Chrono Cross and Spongebob? I know there are 46 open issues on the github but it seems like most of them are not an actual issue with the core
Nuclear Strike , Parappa the Rapper Japan version
Virtual Pool 
I spent about 40 hours on Parappa the Rapper, and maybe someday I'll succeed, but for now I think it's beyond repair.
I tried here too, but without success.
I try to focus only on the CD; if I start looking in every direction, I won't do anything right.
I wouldnāt waste your time on that one unless youāre really motivated to do it just for fun
Itās hardly the most important game in the library š
Iām probably the only person whoād play it š
Robert and Kuba both looked into it and it seems very tough to diagnose
It's amazing how many different games expect behaviors that sometimes seem illogical. There are many things where the real drive simply ignores them, and the game works even though it's doing something that's not quite right.
I see it as more of a "fixing an issue with an inaccuracy in the core" rather than "getting a game nobody wolud play to work", but I also understand proritizing what you can realistically work on and what people would be more interested in getting working
Also so what's broken in the Japanese version of Parappa?
Intro
Reminds me of a popular old story of a programmer who had basically manually written the binary code of his program, and because of this allowed a loop with no end condition to still function because he knew where the computer (a really REALLY old one) would be on it's storage drum during that operation to read the variable, or something like that
Sure, but I was just making clear that when I mentioned it, I wasnāt making a ādemandā or request of Kuba
Well yeah, I am not either in case it wasn't clear, just wondering what was left on the core
Very little that most people would notice imo
I don't think anyone is going to rewrite the game code. Constructor is completely playable, and the fact that some parts of the menu flash occasionally doesn't make it unplayable.
Also reminds me of when I was trying to apply a fan patch to this one PSX game, which game in three parts, and the more parts I added the glitchier it became until it stopped booting at all... but it worked in some emulators, others threw read errors
Apparently, the patch files only changed the data directly on the game's files in the image, and didn't fix the error correction data associated with those areas of the disk that were desperately trying and failing to revert the changes the patches did, thinking they were errors
Had to use an app to re-calculate the error correction data after patching to get it to work right
I finished putting 700+ PS1 chd's onto their own respective folders, was a pain, but per game Mem cards were worth it
You remembered NOT to put each disk of a multi-disk game in it's own folder though, right?
don't worry they are in one forlder
I normally keep my games in bin/cue format on my PC and just make them chd for my mister, so I have a script atht converts games to CHD, puts them in a folder, and deletes the bin/cue
Using the optimized CHD settings in the sticky here
Why does only the Japanese version of Parappa the Rapper break?
The Japanese version does a different unique sequence stop -> seek -> play
The good news is that we no longer need a workaround in the form of a backward seek hack for Dave Mirra/Thrasher games.
It's all thanks to @dark mountain and his game Burger Burger š , which stopped working and forced me to analyze the code and make changes for INT1. The issue wasn't caused by backward seek itself, but by interrupt ordering.. There was a race condition between int1 and int3. Please test Dave Mirra / Remix again with latest test core or unstable and let me know. I'll be happy to remove this hack š
Happy to say a big,fat joke and it finishes as a fix on the core. š
thanks Zet! š»
I hope that one day we will find a suitable solution for MGS and the reverb problem during the Codec discussions.
In kuba-j we trust! š
I will definitely come back to this topic.
Thank you for the continued work you guys are all putting into the core. It's all very much appreciated!
I thought youād resolved it a while back? Or was it just a small improvement rather than fix?
Nice to see the blue team working together ā¤ļø
I only made a test core. I need to come back to this topic and do it properly. I just focused on other things.
Ah, gotcha. Thanks for clarifying
There's also a Burger Burger 2. Does that work?
We need to make sure the burgers are cooked properly. š
Burger Burger 2 2
I should check to see if the Midway Collection 2 with Burgertime works.
Burgers work, we are goodš
just put the burgers in the bag bro
What about fries?
What about her?
The MGS fix is not merged on main yet, isn't it? At least there was a fix already, I don't remember. Or was it just some talk about the transmitter sounds being off or something?
No, it was only test core
I've noticed that with the last two unstable versions, Gradius Gaiden intro video is freezing again (during the explosion part)
Darius Gaiden
Yes, that's how it will be for now. For now, it has to be that way so as not to disrupt other games where timings matters.
Fair enough š
There is a simple workaround: turbo low, or fast seek option, cd speed 1x
if (calcSeekTime = '1') then
addSeekTime <= '1';
-- todo: research more accurate values
if (diffLBA < 3) then

I tried a few changes here and Darius Gaiden works
i'll fiddle with those then
Sucks that something has to break to fix something else š
This game has always had this problem; the fact that it worked for the last few weeks was just luck.
š Do we even have any idea what is causing it? Weird that more retail games are breaking as inaccuracies are fixed
Even changing the seek time value fixes this game.
-- todo: research more accurate values
Man, with it being so picky it makes me wonder how no games had issues across all the PSX revisions
Darius Gaiden has been doing this with every stable core for as long as I can remember. It's not a new issue. We need to find the real cause.
Many games expect specific drive behavior. A thousand games may work, but one will be unhappy. We do not have a realistically modeled CD-ROM drive. Sometimes it's worth asking yourself whether fixing one niche title is worth breaking 10 other games and then patching things up again.
I don't even know if everything can be fixed (github issues)
It really isn't as easy as some people might think.
If it were easy youāve have done it already š
Youāve been doing great work ā¤ļø
Thanksš»
We don't have correct seek times, correct pause/unpause, spin up/down or command times.
If you tweak one, another will break.
Only real solution would be to research ALL of them or live with best guess.
Keep in mind that it took Xstation years to get most things fine and it didn't even have to care about all timings, e.g. command timing is not handled by xstation but still taken from original CD controller
Whatever both of you have done is amazing. The vast majority of games work perfectly. Itās a handful of niche titles (all of which are well known now) which need workarounds. Itās no big deal
try this please
Bob desinterlacing option is broken on that build (vibrating texts even on the Bios screen).
Maybe only test that test core with the Weave algorithm option.
I'm trying on a second MiSTer right now.
Yep.
2 MiSTer systems are fine. One another + the SS1 don't like it.
Anyway, let's test some games.
As long I have some mobile phone connection since last hour & power supply at home is back.
I think about it too.
a fair few did
This one works fine for me. No more freeze on Gradius Gaiden and i don't see any problem with any of my other games so far but i'll keep on checking with more titles š
Same for me, but I'm limited at the moment for more tests.
It's not a big change; I can implement it.
Core is now perfect!!

@ivory verge Based on your work on this core, what percentage of compatibility do we have with games? 95%?
Are there even any games that don't work?
Itās probably higher than 99.99%
Perhaps I asked the question wrong.
@ivory verge According to your work, what is the state of the core in percentage? 95%?
96.69%
all full set is around 10000 titles.
Are we counting disc drive emulation?
the answer depends why you care
@dusk berry Youāll have to comb through the GitHub issues to get a sense of how close to perfect the core is - https://github.com/MiSTer-devel/PSX_MiSTer/issues?page=1
A lot of them are already addressed or arenāt bugs in the first place so youāll likely need to read each one to see if itās still valid. Iād consider that the source of truth to how close to 100% it is.
I believe around 90-100%.
Much higher than 90%. Itās likely in the 99% range.
there's 10,000 titles and we know of like, < 20 legit bugs at this point
Because it's rare that we thoroughly test all 10,000: all the demos, press games, different print runs of the same game...
99.986%
Based on MobyGames saying thereās 3,169 PS1 games and even counting all the bugs.
we canāt assume incompatibility if we donāt know, we can only assume it works until proven otherwise
With 4100 games and 46 github issues is 98,88% š
large parts of core behavior are basically nailed down by various testroms anyway
How do I do percentages
This was an honest question lol
Thatās 99.9887%
So effectively 99.99%
@dusk berry
assuming all the current bugs are valid is wildly pessimistic too
Yeah we also know thatās not the case
But itās tough to go higher than 99.99% lmao
for all intents and purposes, based purely on percentages. @dusk berry you can assume itās 100%, unless you really care about that 0.011%
Then fine itās 99.99% lolol
Is the 2001 PS1 port of Yeah Yeah Beebis running on MiSTer yet?
yes
100% confirmed, then. We can end development on the core, everyone. Good job.
Itās funny, that dude clearly had an agenda and through math we shot it down lol
Yeah, a large chunk of them appear to be something wrong with the image, or the same as real hardware, or such and aren't actually a bug. There's a lot lf clutter in there
I see anti-mister sentiment online not infrequently and itās always funny to me. No one is saying you have to buy a mister, if you are fine with software emulation then good for you.
Fucking video games
The mister has three huge advantages over traditional emulation: easy analog output, no added system-level latency, and (basically) no fiddling with settings for games to run well.
if you're a speedrunner in a highly competitive game it might still not be good enough
for everyone else its basically flawless
You think up of a number that goes "Eh, that feels about right" or "I really want this number to correct" and boom, you have a percentage!
... I was going to follow that up with a simpons gif but it does not appear to be in gipfy
Software emulation is amazing. Like DuckStation is the GOAT. I donāt know or care which is more accurate between the MiSTer core or DuckStation because itās an irrelevant comparison.
pro tip: itās my PS1, get flexed on emulation nerds
duckstation is awesome yeah
Duckstation is cool and for a retro handheld device you canāt expect any better.
i've been using duckstation for android lately and it rules having such good ps1 emulation on the go
Iām kidding I havenāt touched my real PS1 games since MiSTer core
But MiSTer will still win in terms of latency.
I am jealous of you Androids!!!
get one!
hellllll no, I have a social status I need to maintain
Retroid Pocket 6 is out now. Or you can get the previous Retroid Pocket G2 for a bit less.
Iām looking to upgrade from my Retroid Pocket 3+, since it came with a defective screen. Still deciding on which model Iām gonna get.
i like the odin2 portal, more of a steamdeck formfactor, 120hz oled screen etc
Yeah if you can afford Odin 2 definitely go for that, youāll never need anything else.
Too expensive and too big for me though. I like the slightly-less-thab-Switch Lite size of the Retroids.
Yeah they are pretty cool.
Would be good for Dragon Quest and Sonic Rush, games that spread content vertically.
yeah and ds/3ds ofc
Dragon Quest and Sonic Rush are DS games, lol
You love your Blackberry, I get it
I keep getting āunsafe option usedā message when launching psx games but it doesnāt look like I have any of the unsafe options enabled. Anyone have any ideas?
When removing the hack for Dave Mirra, I forgot to remove bit [93] for the warning.
No worries, Iād been messing with the unsafe options so assumed it was something Iād missed somehow
Are there recommended video settings for CRT use or is it more of a whatever feels good kinda thing
Maybe you are the unsafe option???
Robby shoving a mirror in my face
corrected , thanks!
Practice safe gaming: use the core defaults
@devout jolt You must have saved the settings with the backward seek hack option enabled. Return to the previous unstable core, disable this option, and save the settings. The warning will disappear.
smh. Blue practicing unsafe gaming
Unsafe gaming > unsafe sax
Practice safe PSX
megaman 8 looks so nice
It fares visually better by not having copious amounts of Resident Evil-grade CGI in the backgrounds
It also doesn't look like an nes game so even better
It would be nice if someone translated that FMV game for the PS2
try the saturn version when you get the chance 
Does the saturn version have any differences?
quite a few. it has some nicer graphical effects in a few stages, different/higher-quality music, two exclusive bosses, more bolts to collect and an art gallery
Oh interesting I would have automatically assumed the ps1 would be superior
There must be some slowdown at least?
not a hint of lag, as far as i remember. X4 is similarly superior, though to a lesser degree
Saturn 8 has crummier FMV/voice samples/sound effects so it's not a straight upgrade.
i mean, most saturn games are like that, so it's kind of to be expected
the extra content more than makes up for it
There is slowdown when I played it, not sure if that was present on real hardware though or if it was single-ram shenanigans
But yeah, there are two extra optional sort of mini-boss/boss fights
Of ||Cutman|| and ||Woodman||
there's no noticeable slowdown on real hardware, so i have to imagine it's just the single RAM core doing it's thing
š
Single RAM š
non canon mister...
MiSTer Pro 
Ololol single ram, can you imagine? š
sorry if this is the wrong place to ask, i just got an snac adapter and i can't get inputs to work with psx
the analog light on my dualshock lights up but that's it
you mean in game, yeah?
not in the mister menu or anything like that - it's not working once a game loads
yeah in game, i know it doesn't work on the mister menu
which stack and io board do you have?
š¤¦āāļøand now all of a sudden it's working
certain games won't work in dualshock mode, usually if it's supported the game will turn the red light on after boot.
but if you hit the button and turn it on it may not work on all games.
ahh thank you
sorry i'm a ps2 kid so i never realized some games don't work like that
im a sega genesis kid š¢
prehistoric gamer
PS1 came out in 94 or 95, the dualshock didn't come out til 97 so all games before around there don't supprt DS
i still have the vcr i grew up watching Bob the Builder tapes on
Bob the Builder
For me its Mr. Wizard and Wishbone.
ancient gamer? time to walk into the sea
