Thanks guys

Skybeaux, thanks for the info re Stern using the same game chips in more than one game.. makes sense now. I thought i was going mad when Drac played as normal with this board hooked up

Its the first time i've ever come across game ROMs being soldered directly into the board.. glad i didnt have to remove them!! sometimes its bad enough removing them when they're in sockets!! And i was glad to see it fire up and work pretty quickly. I started on this board yesterday mid afternoon, worked on it for a few hours then and finished it this morning about 10.30ish!!
