After doing some research to the Model 2 hardware, you'll need to either completely rewire (which wouldn't be so bad, but you couldn't use the VF2 board anyore) or get a Model 2 --> JAMMA Adaptor. In one of your threads someone showed you a picture of one.
I did a brief Google search, and came up with nada, however. But someone, somewhere, must know something about it. Just not me.
