Hi all, I am trying to find out what the 6510 sees at addresses $1000 - $7FFF in "ultimax mode". My code kept crashing when I tried switching into ultimax mode (I had the ML at $2000) and as soon as I moved the ML to $0F00 (toggling /EXROM & /GAME with an external latch at $DE00, ala super snapshot) it worked on the first go... What decodes ULTIMAX addresses, the PLA? Could someone list how the PLA behaves when /EXROM = 1 & /GAME = 0 ??? The c64 PRG does a piss-poor job, as per usual, of explaining it saying only $1000-7FFF and $A000-CFFF is "OPEN" in ultimax mode.
