Thanks for the fast replies. I tried your suggestion first headkaze, but I'm not sure what's going on now. When it boots up, it stops loading and there are two consoles open, one for gameex.exe and another for cpwizard.exe. Just two boxes open, nothing goes beyond that. I also tried your suggestion bkenobi, or well I was going to try it. Apparently XP Home doesn't have gpedit.msc . I tried following a guide online for adding it to XP Home, however after successfully getting it onto the Home machine there isn't any scripts option. From what I've read so far that's just as much as you can possibly get transfered onto XP Home. Any other ideas? I'm thinking I'm either going to have to install XP Pro on my cabinet or forget about instasheller for now. Otherwise, is the .121 bezel patch only for MAME .121, or will it work for .123? (I currently have .123 on the cabinet) I tried patching the source with that diff patch but when I pause MAME the image of the controls doesn't come up.
