After finally receiving the SamSho64 kit from Vektorlogic last week my personal collection of Hyper 64 games is now complete - I own all four fighters and four motherboards. Unfortunately NONE of them will work with my selfmade supergun, I get neither sound nor picture (the TV screen only flashes either blue or red when I switch channels otherwise it stays dark). I've owned three of the four Hyper kits since last summer and they did work fine on my candy cab (before the cab's monitor went bust a few months ago, sadly I haven't found the time to replace it yet). As for the supergun, it works flawlessly with both MVS and PGM games/ motherboards. Any idea what could be wrong?
