PSP emulator in C++ with dynarec JIT for x86, ARM, MIPS

PPSSPP is a HLE “high level emulation” emulator, it simulates the PSP OS as seen by the game rather than the full hardware. A program running on the PSP OS can send raw display lists to the graphics chips, but can’t access the flash controller or the Media Engine directly, instead it has to go through libraries and the PSP OS kernel. We simply simulate these. This is a lot of work though, the PSP OS is large and has plenty of functionality so achieving 100 compatibility is difficult bordering on the impossible. We can get close though.
