I am attempting to help a person convert their Turtles in Time board to two player. I already tried programming the UDA two player program rom set and all I get is a white flashing screen. The UAA 4 player roms play fine. The board itself is a conversion from another game, but I am not sure from which one. The only other files I can see that are different between the two player and four players are the .nv files. I am seeking input for the next step to take please. Any help would be appreciated.
Thanks!
