So put together a kit supergun for a MVS1B, everything works but the coin button. It's being picked up as SELECT but is not registering a coin. I'm thinking that this is a BIOS issue where the supergun was designed with UniBIOS in mind (which maps select to select+coin) but not sure (I'm using the stock Asia BIOS). Anyone have any insights? Should add that there are coin buttons on the supergun that work fine. It's only the coin button signal from the DB15 that's not working.
Edit: Confirmed that Select=Coin is a UniBIOS thing. Not a big deal since I can put the MVS board on freeplay and at some point I may put the UniBIOS in it. Think I could also jumper some pins on the JAMMA to get the same effect, but don't really feel the need.
