You must have a bad ROM or the header was read incorrectly, this mapper is only used for After Burner.

I got a bit further by trying different settings but I don't think this game is fully playable yet.

Disable "native return address", disable "NMI mode, at vblank".

So I have it working somewhat now that it doesn't crash on any input.
but when interacting with the villagers the colors flash between
normal and negative palettes. Game crashes at first save point
before you enter the first dungeon.

I just tried disabling "Stack page 01" and it seems to fix the crashes.

The flashing colors are caused by the game attempting to change palette in the middle of a frame which Project Nested doesn't support yet.

I have that disabled already, it crashes right after the witch doctor lady saves my game and the game tries to load the dungeon
