No.17378 dink Tester Jan 31, 2020, 03:28	Kale, This one was easy, c081 needs to be added as a mirror for "BUTTONS" (c080) in sparkman's mem map. best regards, - dink (fb dev)
No.17388 dink Tester Feb 4, 2020, 01:27	more info: the game's service mode reads from c080, but in-game it reads from c081 for player2's read of "BUTTONS". I can only guess that some of the address lines aren't being used here (notably bit 0).
