Can anyone tell me what the state-of-the-art in original xbox emulation is and what makes the system harder to emulate than other systems of the time period? Is it simply that the xbox is more powerful than these other systems? Is there something about the xbox hardware that makes it difficult to emulate? Is it like the N64 where too much focus was given to buggy broken HLE emulators (UltraHLE in the case of N64, CXBX or whatever it was in the case of XBOX) and not enough given to proper low level emulation?
