IF IT ISN’T COMPLETELY OBVIOUS Design a hardware-based NES emulator! • 6502 Assembly/Machine. The NES main chip was the 2A03, which was effectively a 6502 with no decimal mode, and an added audio synthesizer unit. 6502 was originally written in a different age, a time when the majority of developers were writing assembly directly, rather than in these new-fangled high-level programming languages. Videogame emulation dawned in the 1990s and exploded during the 2000s. Let's start by giving it some context - technically the full name of the CPU is MOS Technology 6502. • Jeremy Chadwick for 'Nintendo Entertainment System Documentation' [7]. Personal.
