LD,
I downloaded and tried to run the dgen program. It initially opens a black background window on the screen then crashes with a \"Fatal signal: Segmentation Fault (SDL Parachute Deployed)\" error. I have tried numerous ROMs all with the same result. The only one which appeared to work for a little bit before crashing was \"Sonic 1\". It crashes after the SEGA logo draws on the screen. I hope this helps out...
Thanks for all the work,
