libretro-core-info VS Steam-Deck-RA-Core-Updater

Some of the core info files in Onion may need updating (you can search libretro docs to understand whether a specific core supports netplay and which save state format), also see recent core info files here (these may not represent the build of the core available in Onion). If replacing/updating core info files, you should also delete your core_info.cache (in the same folder).

The best way to do it would be to dynamically generate a dat from files listed in each core definition file at https://github.com/libretro/libretro-core-info. However, even those definition files don't list everything (key/unique console data for citra etc., pcsx2 bios)

Git clones the Libretro core info files into your cores directory

I've been trying to setup RetroArch on my steam deck, and I'm trying to use the Steam version to use those sweet-sweet cloud saves. I need to use cores that aren't in the steam version, but I can't figure out side loading on linux. I downloaded the Linux x86_64 cores from the repository, as well as info files from this repo.

From a quick analysis of https://github.com/libretro/libretro-super/tree/master/dist/info, there are about 30 hardware-rendered cores available on retroarch :

As I discovered the hard way, this doesn't include the core info files. Your cores won't be usable at all in Retroarch until you place the corresponding info file alongside it in the folder too. You can get them here

Check out my github, i made a tool for exactly this. https://github.com/lajoshanostra/Steam-Deck-RA-Core-Updater
