Name Description
6502.txt The (to me) infamous 6502.txt. At first when I got this file I noticed that many things in it were inaccurate, so I slightly revised it to provide more accurate information. I'll inform you later on when I've updated it as well as I can. I'll add some more adressing modes info and some more opcode stuff.
65C02 reference(html) This is a nice reference doc to the 6502 processor that explains what opcodes exist and somewhat what they do. It's a good start to read this, but it doesn't give you much information. For example you'd still need to figure out a lot by yourself if you used only this document for your programming. Please note also that this is actually a reference to the 65C02 and not the 6502, so if you are going to emulate the 6502 you won't need some of the opcodes that are listed in this reference(for example TSB, STZ, etc.)
EMU 6502 source code This is the 6502 core that was used in EMU earlier. This isn't really a tech doc, but it's a good thing to base your learning on, since it's rather "unproffesionally" programmed. Which isn't a bad thing, mind you :)
Sardu's 6502 core If you can make use of this and you want a really good 6502 core for an emulator that involves a 6502 cpu core, then use this. This is the 6502 core that Sardu used for NESTicle, and I think that Sardu will stand strong as a brand for good quality and speed for quite some time. ASM.
V16 Want to make an emulator that involves the 6502 in Visual Basic? Then you can either use this 6502 core or base your programming on it.
