There is a 2p version of most of the beat-em-ups (TMNT, xmen, simpsons, etc) Thel let you choose your character.
Yeah, but I want to play 4 player...
then you need any of the following:
- 4 player coin door
- 4 dedicated coin buttons
- 2 player coin door + 2 coin buttons for 3p and 4p
- one button that will credit all 4, but then you'll be stuck with 4 players on screen whenever you hit it even if you don't have 4 people playing.
AFAIK, all the 4p versions of these games don't allow player selection, but the 2p versions do. if you want to play 4p, you need 4 dedicated coin buttons of some type.
