PPSSPP is designed to emulate the MIPS architecture of the Sony PlayStation Portable. The PSP primarily utilizes file formats such as (disc images) or .CSO (compressed ISOs). These files contain executable code compiled specifically for the MIPS processor. PPSSPP interprets these instructions and translates them for the host device (Android, PC, etc.). It has no capability to read Nintendo Switch files, nor can it process code meant for x86 or x64 consoles like the PS4 or Xbox One.
