The article notes that the cartridge had some extra bank switching inside it though, as it went over the address space limit for HuCards.

If they had just let you remap the controls so you had fierce and round house, the two button controller would have been serviceable. All the ports of that game are good. I’ve compared them side by side (SNES, Genesis, PCE) and they’re frankly all fun.

I did have a PCB worked up that lets you convert anything to a PC Engine controller. Can’t give them away!
