You're right, I am so sorry I did not provide enough informations.
Here they are.

Pi Model or other hardware: RPI 4
Power Supply used: official one
RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): Linux retropie 5.10.17-v7l+ #1403 SMP Mon Feb 22 11:33:35 GMT 2021 armv7l GNU/Linux
Built From: (Pre made SD Image on RetroPie website, updated via the retropie-setup script.
USB Devices connected:
Controller used: arcade cabinet (virtual keyboard) and Retro-bit SEGA MegaDrive 6 buttons pad
Error messages received: [KMS/EGL]: Did not find suitable video mode for 256 x 240.
Emulator: the emulator which is in concern is lr-pcsx-rearmed
Attachment of config files:

/opt/retropie/configs/psx/retroarch.cfg
/opt/retropie/configs/all/retroarch.cfg
/opt/retropie/configs/all/retroarch-core-options.cfg

How to replicate the problem: juste by setting the resolution of RPI4 by any other than 256x240 one in the /bootconfig.txt file.

Looking at the configuration files, I see that the video resolution is not set there, so that's ok. Do you have a per-game configuration or override that sets the video resolution to 256x240 for this game ?
The system has only 1 resolution available (the one you've set via /boot/config.txt), but for some reason RetroArch tries to switch to 256 x 240.

Btw, the lines about multitap added in /opt/retropie/configs/psx/retroarch.cfg have no effect, since they're actually core options - same options are already set in the core options file.

I indeed checked that and did not found any resolution setting for the emulator anywhere.
I do not have any per--game configuration file for this emulator. I tried with 3 different games and I always experience the same issue. Is there any chance the resolution is set in another file ?

RetroArch does that only with lr-pcsx-rearmed. All the other emulators automatically use the native (the one set in /boot/config.txt) resolution.

It worth mentioning that I found that bug reported in some other threads (in 2016) and the solution was to reinstall the emulator from source. So I reinstalled the emulator twice, once from pre-compiled binary, once from sources, and the bug still remains.

Yeah I saw that. I set that earlier to fix the "no controller recognized" bug. I'll delete those lines in the core file.

I don't know if it's not the same thing - the video backend for the Pi4 (DRM/KMS) is quite diffferent from the one available in earlier models.

Can you upload a verbose log from the emulator to pastebin.com and post the link ?

@mitu

Sure, here are the 3 files that re generated in the/dev/shm/directory :

Thx a lot for the time you spend to help me.

runcommand.log

You have a core override for lr-pcsx-rearmed:

[INFO] [Overrides] core-specific overrides found at /home/pi/.config/retroarch/config/PCSX-ReARMed/PCSX-ReARMed.cfg.

Delete the file and see if the games will start.

@mitu
Damn, you're right. I have no idea why this file existed.
Game started as soon as I deleted it. Thx a lot !

I still have a question tho : according to the RetroPie doc page :

global configuration is set in /opt/retropie/configs/all/retroarch.cfg
system specific configuration is set in /opt/retropie/configs/psx/retroarch.cfg
rom specific configuration is set in /home/pi/RetroPie/roms/psx/Rayman.cfg

Attempting to set a specific resolution for Rayman, I figured out that the file /home/pi/RetroPie/roms/psx/Rayman.cfg is absolutely not read at game start whereas /opt/retropie/configs/psx/retroarch.cfg is.

Moreovoer, investigating the runcommand.log file I read that :

[INFO] [Overrides] no core-specific overrides found at /home/pi/.config/retroarch/config/PCSX-ReARMed/PCSX-ReARMed.cfg.
[INFO] [Overrides] no content-dir-specific overrides found at /home/pi/.config/retroarch/config/PCSX-ReARMed/psx.cfg.
[INFO] [Overrides] no game-specific overrides found at /home/pi/.config/retroarch/config/PCSX-ReARMed/Rayman.cfg.

Then I moved the /home/pi/RetroPie/roms/psx/Rayman.cfg file to the/ome/pi/.config/retroarch/config/PCSX-ReARMed/ and figured out that in this case, modifications are taken into account...

So, is the doc page obsolete or is there something I missed ?

The .cfg must contain the full file name, including the extension. So it's Rayman.cue.cfg, not just Rayman.cfg.

You' re right. Thanks a lot.
