Someone mentioned this topic in another thread so I thought it would make a great discussion.
It would be nice if there was a comprehensive list of what arcade PCBs can be converted to other games with simple ROM swaps and minor mods, without having to strip original boards of parts like custom chips, etc. For example, having to destroy a Ghost and Ghouls board in order to convert another board to Ghost and Ghouls.
Off the top of my head, here's the ones I know of:
Street Fighter: Hyper Fighter to Ghouls and Ghosts - EPROMs, minor mods and some GAL chips programmed
Mappy to Dig Dug II - EPROMs, minor mods and a couple chips from a Super Pacman board
Road Blasters to Marble Madness - EPROMs and it requires RB daughter cards with the right protection chip and main boards with LETA chips
Williams boards (except Defender and Sinistar) to Alien Arena - EPROM swap and disabling of the watchdog
Tri-pool to Uncle Poo or Loverboy - Supposed to be a straight EPROM swap
Star Fire to Star Fire II - Straight EPROM swap
Scramble to Scorpion, Mighty Monkey, Lost Tomb, Strategy X - various mods
Galaxian to Dig Dug, Pacman, Ms Pacman, Space Invaders - various mods
