MAME and MESS just completely rewrote their 6502 implementation. Crazy! (I mean, crazy GREAT, of course.)

Here is the link. For those (like me) unfamiliar with the terms, MAME = Multiple Arcade Machine Emulator. MESS = Multi Emulator Super System

Multiple Arcade Machine Emulator is awesome, for the PC! If you have the ROMs that is... I've not played with MAME for over a year. Alot of the ROMs I was able to download from a website back then, not sure about nowadays though... The original Pacman was always hardest to find!

But what you have found here Dr. Jeff is awesome. This guy is committed! Still reading...

Excellent find! I see they used perfect6502 as a reference - that's the visual6502 simulator ported to C.

I had trouble squaring their verbal description of ASL Abs with the actual behaviour:

but it turns out I'd misread the description.
