The original roms for The Simpsons Arcade game did not include an option for free play. This rom by DogP (unofficial) replaces the chip at location 15C (J12) to offer Free Play Only. You will have to keep/reinstall your old chip to take coins again. This version requires you must change the setting "7. START BUTTON" to "WITH START BUTTONS to enable shared credits.
****This is only compatible with 4P rom version and not the 2 player eproms/version.****
This is a working rom pull from a board that was returned to stock.
You MUST pair up the set you need with the roms you are currently running. Between the different regions, and versions, different cabinets either had start buttons to start the game, or used the player's action buttons, and no start buttons were installed.
After installing these or reverting back to your old version, you must hold the test/reset button in on first boot to clear the memory, or it won't boot properly.
Free Play hack v1.0 for TMNT (4P sets)
by Pat Daderko (DogP)
This is a freeplay hack for the 4 player (2P ROMs are not supported) TMNT arcade game. This hack does freeplay only... there is no DIP or menu selection to enable/disable free/coin play.
All known regions in MAME are in this hack, named corresponding to the name of the MAME set. To determine which set you have, look at the numbers on the chips at J15 and K15. The numbers are:
tmnt: 963 X21, 963 X22
tmntu: 963 R21, 963 R22
tmntua: 963 J21, 963 J22
tmntj: 963 221, 963 222
tmht: 963 F21, 963 F22
tmhta: 963 S21, 963 S22
tmhtb: (unknown)
To use, burn the freeplay ROMs to 27C010 EPROMs and swap with the corresponding chips at locations J17 and K17. If your J15 and K15 ROMs differ than those listed above, you'll need to also burn the J15 and K15 chips from the corresponding MAME set you'd like to use.
As always, use at your own risk... this hack has been tested in MAME and on a TMNT PCB, but only briefly.
