M68K and Genesis VDP cheat sheets now available
Posted: Sun Mar 18, 2018 12:47 am
Hi all,
I'm new here and pretty much a newbie to programming on the Genesis /Mega Drive. Two of the biggest hurdles have been for me so far: 68000 programming, and making sense of all the different VDP registers.
I couldn't really find anything that brought that information together in a tiny, compact way suitable for memorization study. So, taking from sources like sega2f and MarkeyJester' s detailed information on cycle timings, I've taken a first shot at making some "cheat sheet" documents.
These are works in progress, and would gladly accept error reports or suggestions.
The Ultimate 68000 Cheat Sheet will print on 5 double-sided A4 pages, which can then insert into clear files for easy study. The Ultimate Genesis VDP cheat sheet will print on 2 double-sided pages.
Anyway, here they are for now:

Hope these are helpful to some people. Thanks, Carl
