Is there a way to get RetroArch to load a custom version of the “retroarch-core-options.cfg” file? I tried to use the “–config” command line, but RetroArch crashed (I’m sure because it tried to load it as the standard config file, rather than a core-options config.
My reason for doing this is because I want to have 3 different settings for Neo-Geo games. One for AES with the Uni BIOS, one for MVS with the Uni BIOS, and one with an AES BIOS without using the Uni BIOS (the last one is so that I can get Retro Achievements, since the Retro Achievements website doesn’t work with the Uni BIOS). I can use Launch Box to use any command line I want when I launch the game, so using a command line to load different core options config files would be ideal.
I’d also like it to load English as default. I can get English text when I load Baseball Stars 2 with the Uni BIOS, but if I use any of the regular AES BIOS, the language is Japanese. Still not sure why that is. And for some reason, the sound stops working while playing Aero Fighters 2/Sonic Wings 2 when using the Final Burn Alpha core (but not the Final Burn Neo core). Not sure why. Even tried different roms to rule out the possibility of a bad file. This is another reason why I’d like to load different core options - I’m currently using the Final Burn Alpha core for AES & the Final Burn Neo core for MVS games, but the Final Burn Neo core seems to have fewer issues, from my experience.
