Well I know of a couple wich use not too much assembler, however in any situation, assembler is handled perfectly by delphi I will write down your data cuz I am going to need many C++ and delphi seasoned programmers

As for wich emulators to convert well I have a couple of them in mind:

[list=1][*]NES Emulation FCE Ultra[*]SNES Emulation ZSNES[*]Gameboy, Gameboy Color, Gameboy Advance VisualBoy Advance[*]Sega Genesis, Master System, Game gear Gens[/list]
