4 Player Coin setup like Konami cabs?

If you remember the TMNT, or any other Konami 4 player arcade cab, where u insert a credit and the 4 lights flash for P1,2,3 & 4, what would i need to get this working with my upcoming MAME project?? Was it just one coin mech, or was there 4???

My TMNT board currently has a 2P ROM set on it (I need to buy one more blank before I can swap it out for a 4P), but mine seems to work either way.  There are 4 coin inputs (2 on JAMMA and 1 on each additional header for the 3&4P controls) in addition to 4 service credit inputs.  However, putting a credit on player 1 and hitting start on player 2 seems to work just fine, and if you put another credit on player 1 can hit start and join in.  The things you learn by hooking oddball games up to DDR cabinets...

So all i would need would be one coin mech, a credit baord, and set mame up for player 1 to 4 start bitton to the relative buittons on the control panel?
