Normally you would have to install the latest IPA to get the latest cores. If you only wanted a specific core, youd have to download from buildbot, put it into the IPA, then sign it on a computer.
But there’s a way, on device, you can fakesign cores from https://buildbot.libretro.com/nightly/apple/ios-arm64/latest/ https://buildbot.libretro.com/nightly/apple/tvos-arm64/latest/
Download the core you want.
Then, either on device or by SSH, use this command.
ldid -S /path/to/core.dylib
Finally, add the dylib to your modules folder. Thats it!
Again, makes it so you arent forced to update RA to get the latest cores. Also makes it way easier to add updated individual cores, especially if they are only included in ios/latest and not tvos/latest on buildbot.
Case in point, installing the new and improved mupen(n64) core on tvOS!
