Can't run games which require firmware using RetroArch + Lutris

Title says all. I have all the firmware places in ~/.config/retroarch/system and I've pointed the BIOS files location in Lutris to that, but everytime I tried to boot up a game which require the firmware, say PC-98 game (Touhou 1), it give this error:

'np2kai/font.bmp'

Traceback (most recent call last):

  File "/usr/lib/python3.13/site-packages/lutris/exception_backstops.py", line 29, in wrapper
    result = function(*args, **kwargs)

The firmware files are all in "~/.config/retroarch/system", and again, Lutris' BIOS file location is pointed there

Re: Can't run games which require firmware using RetroArch + Lutris

Also, I've replaced the RetroArch from Lutris from 1.13 to 1.20 (recompiled)

Re: Can't run games which require firmware using RetroArch + Lutris

Why are you not just using retroarch from the repos? This looks like lutris being bugged up here. And it appears to try to use a font rather than an actual firmware file.

Re: Can't run games which require firmware using RetroArch + Lutris

I was worried that the repo one might have some stupid quirk + prefer recompiled myself anyway. Btw, this isn't just PC-98 games acting up. Here's a list of system that are acting up
GBA: sgb_bios.bin
PC-Engine: syscard2.pce
Saturn: kronos/saturn_bios.bin
SNES: dsp1.data.rom
All firmware-related files are in ~/.config/retroarch/system

ls ~/.config/retroarch/system

Re: Can't run games which require firmware using RetroArch + Lutris

So someone made an issue last week https://github.com/lutris/lutris/issues/5982
