2 years ago The IRQ counter for that mapper was never implemented with the rewrite. Basically wasn't done at all yet. It's a cycle counter that snaps back to a period value.

On Salamander (J), the bottom part of the screen showing the various ship power-ups should be static but it scrolls horizontally with the playfield and rolls around the screen. Since the power-ups are pivotal to the game experience this renders this particular game unplayable, and it's a favourite of mine. Hopefully it's something simple to fix. I noticed that this issue is present going back to your 2013 fork. PocketNES 9.98 renders this correctly, but you have made so many other improvements since then that it would be a pity to use that old version.
