That's already done by the RetroPie setup, so it's ok.

I've got a RETROARCH-CORE-OPTIONS.CFG file in the /opt/retropie/configs/gb directory (with the setting on 'GB') and one in the /opt/retropie/configs/gbc directory (with the setting on 'GBC').Īnd the EMULATORS.CFG file in each one points to the right directory, eg the one in the GBC directory says Surely it must be Did you read the post carefully ?īesides creating a core options file for each system, you'll have to modify the retroarch.cfg for each system and add an additional line to point RA to that option file: core_options_path = '/opt/retropie/configs/gb/retroarch-core-options.cfg'Īnd core_options_path = '/opt/retropie/configs/gbc/retroarch-core-options.cfg' The ONLY thing that works is making and saving an individual config file for each game, and there are hundreds of the damn things. I've tried setting the option in a game and then hitting 'Save Core Overrides', which does nothing. I've tried adding it to /opt/retropie/configs/gbc/RETROARCH-CORE-OPTIONS.CFG, which does nothing. I've tried adding it to /opt/retropie/configs/gbc/GAMBATTE_LIBRETRO.CFG, which does nothing. (Tried it both with and without the 'gambatte_' part.) I've tried adding it to /opt/retropie/configs/all/retroarch/config/Gambatte/GAMBATTE.CFG, which does nothing. I've tried adding the line to /opt/retropie/configs/gbc/RETROARCH.CFG, which does nothing. Then The Muppets starts in GB Color mode and all is well.īut how do I tell it to run EVERYTHING in the GB Color directory as a Color game? So if I have the line in, say, /opt/retropie/configs/all/retroarch/config/Gambatte/Muppets, The (U). I tracked it down to /opt/retropie/configs/all/RETROARCH-CORE-OPTIONS.CFG, where it's set to 'GB' because I don't want it dicking around trying to run standard GB games in Color mode unless I tell it to. The option is this one: gambatte_gb_hwmode = 'GBC' This seems like it must be a pretty basic question, since having multiple systems that use the same core is built right into RetroPie - but I've searched and searched and truly cannot find the answer.How in the heck do you make Gambatte default to GBC for Game Boy Color games? I have my Color games as a separate platform, but Gambatte insists on trying to run them as mono GB games unless I save a separate config file for every individual game.

(Or maybe a way to put a conditional into retroarch-core-options.cfg?) What I want is a way to override retroarch-core-options.cfg per system. I know I can make per-game core options '.opt' files in /opt/retropie/configs/all/retroarch/config/Gambatte, but to do that for every single GBC game is incredibly tedious. right? Copying this line in there does nothing. And as far as I can tell, all the system-specific config files, like /opt/retropie/configs/gbc/retroarch.cfg, cannot determine core options like this one. The problem with retroarch-core-options.cfg is there's only one such file for all of Retroarch, and it seems indifferent to which system is being launched. Changing it saves a line to /opt/retropie/configs/all/retroarch-core-options.cfg: This can be set in the GUI under Quick Menu-Options-Emulated hardware. Obviously when launched as a GB system I want the core to emulate GB hardware when launched as GBC I want it to emulate GBC hardware. I am using lr-gambatte for both Game Boy and Game Boy Color.
