if i remember correctly, i saw a tv special on bill gates and how he started and it said that he and the other guy(forget his name) actually made an emulator of a computer that ran on their computer so they did not have to buy the other computer. it wasnt too complicated, just a little cpu difference and a different way to access the ram (i think). but, as for released emulators, new would be a good start, but i might even venture to guess that a gameboy one or an older computer system was emulated first. just because the gameboy is monochrome and would be easier than nes
