Ram won't be the problem, as much a cpu power.... Iv heard a lot of devs sayin its one of the hardest consoles to emulate... not sure why this is, but they know what they're on about.. my comment on cpu power may not be true though... Rule of thumb is usually 10× cpu power required to emulate the system.. its not always true but a good rule to go by for LLE anyway.. HLE would require less as your not emulating the entire system, just the way the system is seen by a game.
