@bizt go into the retroarch settings from the emulator. Back out until you see settings and select that. Then go to video, and then change the aspect ratio to either 4:3 or default. Then go back a couple menus and go to to
Configuration, then save core overrides.
Another option if you wanted to keep the stretched out 16:9 image, it turning on Bilinear filtering in the same video menu, and then save the core overrides for that. The filter helps smooth out the chunkyness of ps1 games. Or do a combination of both

@stoo While I haven't been able to replicate the weird performance problem I was getting before, I see why OpenGL is failing intermittently.

Seemingly at random when switching AA values, a shader fails to compile. It doesn't happen every time, but maybe 50% of the time?

When this happens, it says it's falling back to Software rendering, but a black screen appears instead. The game is still running, audio is playing but no display. You can switch internal resolutions up or down to force it to initialize the OpenGL renderer again and it usually comes back.

No idea if this is a bug in duckstation, Retroarch or a GL driver bug. I'm using glcore.

@pedrovay2003 well the keys were leaked many years ago. Possible that they are in there. Or they have some hackey way of decrypting like the programs that will extract a clean iso from a bought pbp.
You may be the one of the very few people to attempt to run a DRMed file in an emulator, because for the most part, it should not work.
Also beetle-psx is practically the same emulator as mendafins.

@w1ck3rm4n we need the log file.

https://retropie.org.uk/docs/Runcommand/#launch-with-verbose-logging

Launch with verbose logging. Copy the log and post it here (via pastebin.com).

An easy way to access the log file (if your Pi is on your home network) is copy it to your roms folder, where you can access it from the network share. Press F4 on your keyboard to exit EmulationStation, then copy the log file with the command:

cp /dev/shm/runcommand.log /home/pi/RetroPie/roms

Then you can access it through the network share from a Windows computer on the same network, by navigating to \\retropie (if your network doesn't recognize hostnames, you can try \\your.pi's.ip.address) in a File Explorer window (you'll have to open "roms," the log file will be inside it.)

@crush ok, thanks.

@crush ok what info you need? Please i want to play some games so much and i sad because not working the bios is is bios folder scph1001.bin and the games is usa version

Ok, I guess there is not much I can do.
Thanks @lostless
Can anybody recommend an adapter that works?

@dreamcastkid That may be true, and they could be defining the same thing or perhaps using a different approach to correct the perspective geometry enhancing the GTE processor or the Emulated Geometry Transform Pipeline . The co-processor for original hardware playstation was called the Geometry Transform Engine. A few plugins available for PCSX-R and EPSXE have GTE accuracy hacks but these plugin options are lost in Retroarch, or perhaps already implimented.

@busywait That did it. Thanks!

@liquidpolicenaut do they still happen if you turn off the dynarec via https://retropie.org.uk/docs/RetroArch-Core-Options/#setting-core-options ? (this may decrease performance)

@dreamcastkid

Thanks, it's empty. I think the emulator crashes all before it has a chance to even log something.

@meltedpineapple ya, that’s what i meant by

ignore the analog part

but i probably should have found / written a more relevant guide !

Thanks this totally fixed it for me. Another similar version here: https://retropie.org.uk/forum/topic/28656/start-button-on-psx-emulator-doesn-t-work/2?_=1608109096986

seems odd this is the default. I never would have found that on my own!

@george-spiggott said in General Duckstation discussion:

Has anyone succeeded at running any games at 2x resolution at a reasonable speed? Even on an overclocked Pi4 doesn't seem up to this. This is certainly an emulator that will grow in usefulness as the capability of Raspberry Pis increase although I think I will probably stick with PCSX Rearmed in the short term.

I have been running a few games (spyro, ff1/2, crash bandicoot, ONE) at 4x res, with 32x msaa at over full speed (Vulkan hardware rendering). My pi4 is overclocked, but pretty much stock RetroPie.

Thank you for your post. Having two SF30 pro and got the same issue.
After configuring as per you post above, the mapping is strange. For example, the hotkey is used to jump under tomb raider.
In other words, the controller map is not as per lib-retro "standard" for psx. Any idea how to be back on standard lib retro mapping ?
My config : retropie 4.7.3 / pi 4

@kikus said in lr-pcsx-rearmed loads but freezes at "Paused." black screen:

Built From: Started from Nachos 64GB image but updated all package from source recently

We don't support 3rd party images. Ask the author(s) of the image for support or use the image from retropie.org.uk/download.

@danmac2 said in No Dialogue or Music in PSX ROMS (pcsx-rearmed):

@dankcushions I have every BIOS you can think of in the bios folder

ok, and the verbose log?

I'm happy to admit I have no idea how to run this program. I tried putting "psxpackager -i E:\No-Intro Collection\ROMs\psx\Rayman (USA).7z" into CMD and nothing happened. Tried multiple variations of above. Updated to newest version. Ran exe. Nothing. Tried cmd "E:\PSXPackager.v1.4.1>PSXPACKAGER.exe -i E:\No-Intro Collection\ROMs\psx\Rayman (USA).7z" and multiple vartiations. All nothing. Can someone please explain like I'm 5?
