Retropie 4.5 to 4.6 update broke all my mame roms

I recently made a fresh image of retropie 4.6 on a raspberry pi 4, but restored my old romsets. All seem to be working as intended, except every single mame rom boots me back to the game selection screen, just like it would when a rom is incompatible. The majority of the roms are for mame-2003, and they worked absolutely fine on retropie 4.5. Does anyone know of anything that I can try? I've tried reinstalling the relevant mame packages, double checking that the correct mame emulator was running etc. But nothing works at all.

Can you post a verbose log from running such game on the new system ? Get the log file and post it on pastebin.com, then provide the link to it.

Thanks for the reply, here's the log:

Hopefully that might shed some more light!

For some reason, the configuration you have (for RetroArch) is no correct:

[INFO] [SDL2]: Available renderers (change with $SDL_RENDER_DRIVER):
[INFO] 	opengl
[INFO] 	opengles2
[INFO] 	opengles
[INFO] 	software
[INFO] [SDL2]: Available displays:

Did you modify your RetroArch configuration from the defaults that RetroPie sets ?

@mitu when I transferred over the roms, I also transferred over the config data and artwork in an attempt to keep the metadata, so I'm guessing that I've copied over a file that shouldn't have been copied. Is there a file I can delete or modify to restore the defaults?

If the issue appears only for arcade ROMs, then most likely your retroarch.cfg for that system is incorrect. Find the file \\retropie\configs\arcade\retroarch.cfg and replace its contents with

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line

input_remapping_directory = "/opt/retropie/configs/arcade/"

#include "/opt/retropie/configs/all/retroarch.cfg"

Try again to boot an arcade ROM and see if it works.
