I know but Android is Linux based like RecallboxOS. I assume that it's possible to integrate the Linux version of PPSSPP or am I that wrong?

Thanks for your answer.   A NDS emulator would be really neat though.   But why is PPSSPP still not working properly? It works on my old Huawei Ascend G330 with some configuration with acceptable Speed. Isn't RPi2 more powerful than an old smartphone?

Hi,   are there any plans to add PPSSPP or a NDS Emulator for Raspberry Pi 2? Or is the hardware still too weak?
