I have the same problem with CoinOps Next and Arcadia 4.  The games scroll wheels work fine but if I launch a game it just goes to black screen. I can hear game in  back ground and I can exit back to scroll wheel and I get a picture again but in games no luck. I have tried ruining the fixes in the fix folder and that did not help. I am running a Nvidia 1660 Super in machine that I am trying to play on.  Any suggestions on how to fix this issue??
