Help saving core option configs with cores that support multiple system emulation. Ex. SameBoy and Genesis Plus GX. in Noobs Posted July 6, 2020 16 hours ago, Zombeaver said: That's correct. There's no equivalent of content directory overrides for core option files. They can only be saved per-game. Your only options to do this are what Headrush stated - either per game (.opt files) or by directing the platforms to a custom retroarch.cfg that has a specified (alternate) location for retroarch-core-options.cfg. That can be accomplished through Launchbox, using command line parameters. You'd make a copy of retroarch.cfg, name it something like master-system.cfg, add a custom command line parameter in LB for Master System of -c "master-system.cfg". Then make a copy of retroarch-core-options.cfg, copy it into a subfolder in Retroarch named something like master-system-core-options, and then specify that path in master-system.cfg in the core_options_path = "" (you'd put it between the quotation marks) line. Repeat for the others. Why is it that you're needing to do this to begin with? I can't think of many good reasons to need to change core options on the basis of platform. Most of the time when one core supports multiple platforms they'll have various core options that are specific to those platforms where they would make sense. Overrides and shader presets per platform are a common need, and easy to accomplish with content directory overrides/shader presets, but I'm not sure why you'd need to change anything in the core options per platform. What exactly is it you're wanting to do? I wanted to enable RGB settings for Genesis and LCD ghosting for Game Gear. I solved the problem by pointing to a custom retroarch-core-options.cfg file in each Sega systems .cfg.
