lr-pcsx-rearmed unable to find suitable video mode

Looks like the 256x240 resolution might have been saved to the configuration file.
Please add more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first. Post the /opt/retropie/configs/psx/retroarch.cfg file on pastebin.com and provide the link.

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.
