Thanks for the replies. I had a friend come around who knows command line and your recommendations, NullPointer, didnt work (but thank you), however Tempest, yours did. I changed Mame version and it started working. You guys rock! Now I have another slight problem. Not sure if should post a new thread but here goes... When I do an update to the games list it only gives me 73 games, however I have over 5000 roms and in mame itself at least half of them work. Under the setup wizard the mame setup is ok in terms of roms location. Please assist.
