I just thought I'd throw this out there since I hadn't seen anyone mention it. 0.5.5 was my first version of this emulator and I couldn't for the life of me figure out why I couldn't get any of my rips or dumps of Skies of Arcadia or Shenmue to work. I tried at least 4 different versions of each game and nothing... Also, when playing Jet Grind Radio using the OpenAL plugin the sound would be horribly out of sync. I then tried DEmul 0.5.4 and was able to play Skies of Arcadia and Shenmue again. Maybe 0.5.5 wasn't tested much?
