Sorry for double posting but I didn't understand something. Lets say I set a map plane A location, how big will it be? Does it end where the next one (ie map window) starts? Or maybe it depends on how much data I put there? Also what kind of data is in there (I assume enigma mappings)? And, are the registers all you had to explain for vdp and that's it, from here on its just questions we ask?
