The issue (for me) is who made it and do you call something a hack even if an official Capcom office did the hacking or some office they license through. Romstar/Capcom USA did it with CPS1 parts (Nightmare Tony told me about it) and there are similar stories out of Mexico for the CPS1/2 era. Even the B board for Pang 3 looks like some sort of licensed Mexican bootleg. On Mighty Pang they didn't change the code but just slapped on an orange shell, kind of hacky choices.
