i can't get battletoads to work well with 1 screen mirroring and the "m" bits wich switchs between 2000 and 2400.
AFAIK 1 screen mirroring means that all nametables points to the same 1K. So writing to 2000, 2400, 2800 and 2C00 writes to 1K wich i think is the first one?
Kevtis AOROM doc says that the "m" bit selects wich NT to display. Does it mean that setting it to "1" all NTs point to 2400 (phisically the second nametable?).
As you can see im little confused.
