How to Run PC Games on PSP (And What Actually Works): You Can't—But Here's What You Can Run

You cannot run PC games (x86/Windows) on a PSP. Architecture mismatch: PC = x86_64 + Windows/macOS/Linux; PSP = MIPS32 (Allegrex) + PSP OS. No translation layer exists.

What You Can Run on PSP

Content Type	Method	Performance
PSP Games (ISO/CSO/PBP)	Custom Firmware (6.61 PRO/LME/Infinity) → Place in `ms0:/ISO/` or `ms0:/PSP/GAME/`	Native (100%)
PS1 Classics / PSX2PSP (POPS)	Convert PS1 .bin/.cue → .PBP (PSX2PSP tool) → `ms0:/PSP/GAME/`	Excellent (hardware GPU assist)
Homebrew (Lua, C, PRX)	CFW → `ms0:/PSP/GAME/APPNAME/`	Native
Retro Emulators	NES (NesterJ), SNES (Snes9xTYL), GBA (gpSP-J, TempGBA), Genesis (Picodrive), N64 (DaedalusX64 — slow), PS1 (POPS)	Good (8/16-bit); Poor (N64/PS1 soft)
