I installed RetroArch on iOS 14 b3 using Sideloadly 0.12. RetroArch itself launch correctly, but cores doesn't load.
After some digging, I found that all RetroArch cores are stored as dylib in the RetroArch app itslef (like RetroArch.app/modules/fbneo_libretro_ios.dylib for the FB Neo core), and when trying to load a core, the following message appears in the console :
/private/var/containers/Bundle/Application/EE93A111-1A1D-48B8-AA90-8FBF216E8BBE/RetroArch.app/modules/fbneo_libretro_ios.dylib not valid: 0xe8008015: A valid provisioning profile for this executable was not found.
Then :
AMFI: code signature validation failed.
So apparently Sideloadly is not signing all dylib contained in an app.
Before iOS 14 b3 I was using Impactor to install RetroArch and it was working fine.
Any idea ?
