I am a bit confused concerning mirroring/one-screen mirroring.
Assume an MMC1-game. What happens if the game switches to one-screen mirroring (nt0) but still writes data to nt1/2/3? Will the data be written to nt0 instead?
Assume this scenario:
1) Horizontal mirroring activated
2) Switches to one-screen mirroring (nametable0)
3) Switches back to horizontal mirroring
What happens after 3) with nametable2&3? Do they still have the contents of nametable0?
