I understand that "converting" a CPS1 SF2 Champion Edition B board to Hyper Fighting involves swapping out just three EPROMs (21, 22, 23.) Has anyone ever considered creating a device to toggle between these so you can easily switch between the two games? This would remove the need for owning a second B board or swapping EPROMs, and putting stress on the A and C boards every time you wanted to play a different game. Something like this which toggles the Kickstart ROM on an Amiga:
