How i wrote in description, i’ve this problem on my GPD XD with Android. Everytime i select a game for PSP or Nintendo 64 Retroarch crash, i tried many solutions but nothing happened. I don’t know i solve, thank’s.
For now better use PPSSPP and mupenplus beta from Google store, both are free and run faster than the Retroarch cores not to mention they got more features, mupenplus beta for example can emulate the transfer pak (only 64 emulator on Android that can do this as of now)
