What a retarded thread. Don't post shit like this if you don't understand emulators or their history.
This will blow your mind, but the emulators you take for granted today needed YEARS of hard work to reach the standard you know and expect today. There was a time when just being able to somewhat emulate mario was a big step forward. N64 emulation was considered something for NASA tier PC's and people would laugh at the idea of smooth, accurate PS2 emulation.
