The bug appeared in: https://github.com/TASVideos/fceux/commit/6145fe22ab8f6eebc71c5e84b14ed5d4ea87b302 (src/boards/bandai.cpp). Before: https://github.com/TASVideos/fceux/blob/0307e3b827da185054e3251bb4165734b890cf59/src/boards/bandai.cpp#L220 Now: https://github.com/TASVideos/fceux/blob/129fbe3c323c56e8224f97afb0fe408df037b760/src/boards/bandai.cpp#L306 Submapper # 4 responds in the CPU $6000-$7FFF address range (https://wiki.nesdev.com/w/index.php?title=INES_Mapper_016). The game works after the fix, but I'm not sure it won't screw something else up.
