Now I know what it takes to build, lets say, a NES emulator, but what about an all in one rom player? This would maybe include Atari, NES, SNES, Genisis, GB, GBC, GBA, ETC., ETC.

I am very good at programming, and I learned about Emulators and how they work by taking the source files and studying them until my head bursts...

I was thinking, why not take all the files, already written in code, and puytting it together? What exactly would that take? I know it may take a year or two, but I love a big challenge.

Feedback please?
