Here it goes again. If it works well, must people argue over emulation, sandbox, virtualization? Personally I could not care less. Does me no good to know for sure. For me, I'd ask Marcan, Crediar, etc. The real pros. NO offense to anyone here.You are wrong, afaik doesn't exist MIOS calls, the game itself handles all hardware access like disc reads, memory card access, controller polls etc.
