In trying to discuss NES 2.0 submapper proposals re: bus conflicts I am finding a lack of available information about mappers 2 and 3.
There is a statement in disch's mapper notes that mapper 2 includes non-UxROM boards that do not have bus conflicts:
I'm trying to find information about this, which games it includes and whether they rely on the lack of bus conflicts, or even if it's true at all. So far the only game I found mentioned was the relatively recent Donkey Kong Pie Factory hack. Has anyone ever run into other examples?
I also have the same question about mapper 3. There is a given example for Cybernoid on a CNROM board that requires bus conflicts, and a Sachen game Colorful Dragon on a non-CNROM board that requires no bus conflicts. Are these the only two edge cases? There seem to be a bunch of non-CNROM games in mapper 3, but do any of these boards prevent bus conflicts, and importantly do any of these games rely on that?

UxROM has bus conflicts, however mapper 002 is meant to be UxROM and compatible. So some mappers which were similar in function, but did not have bus conflicts are included.
