The NES runs on, as just mentioned, a custom NMOS 6502 microprocessor modified for use on the NES by integrating sound generation and assorted I/O registers, which was manufactured by Ricoh and is called RP2A03G. In the licensed category one could argue that the original brick style controller trumps all, followed closely by the dogbone controller. Mindamellett a funkcionalitásban nem maradt el a konkurens. ACME, aka ACME Cross-Assembler for Multiple Environments. The 6502 had relatively few registers (A, X & Y) and they were special-purpose registers. JOT solutions are based on the best applications and modules to enable ultimate designs and performance in minimal forms. An assembler is a program which converts assembly language into binary format (and in particular, since the '2600 uses a 6502-variant processor, we need an assembler that knows how to convert 6502 assembly code into binary). ACME supports the standard assembler stuff like global/local/anonymous labels, offset assembly, conditional assembly and looping assembly.

However, I am having trouble finding this; was wondering if anyone knows a site that has it??. 6502 Assembly programming for the Nintendo Entertainment System (NES) and Famicom The NES was the first games console I owned, compared to the 8 bits I was used to (Like the CPC) it's incredible high speed, and smooth scrolling were really impressive. Doing this, I'd then write a complete program in 6502 assembly code to transform the NES CPU into an externally controllable audio synthesizer.
