Ok I have a tech question. My PCB has a single e-prom mod. The e-prom has a label (fast/slow) on it. I am thinking there is a way to switch from one to the other. I tried the dip switches with no luck. My pac is in fast mode at the moment. Plus is there a way to install the high score save with attract on this hacked PCB.
The original ROM chip, I believe at position 6F if memory serves, was replaced to make it the fast version. If you prefer the stock slow version all you need to do is pull that chip and replace it with a new ROM chip burned with the original data. If you don't have a ROM burner and/or don't know how to do this,

If you want both slow and fast versions to be available and selectable, I believe a Pac multi kit is the only way to go unless you convert your cab to a 60-in-1.
Someone else will have to answer the high score save question. Most if not all of the Pac multis will do high score save, but I don't know if there is just a straight high score save mod for an otherwise stock board.
