Im currently running the latest version of mame with the mamewah frontend. When running certain games, particularly ones that require a chd, the monitor will go into sleep mode when trying to load the game. I have to hit escape to go back to the frontend. Most games work fine but there are a handfull that tend to do that, and i know the game works.
Also, what speed machine do you need to play certain games like NFL blitz or Gauntlet dark legacy? Are they playable on say a 1.5ghz Amd? TIA
