No matter what I do, I can't get the original After Burner to work on MAME32. I've tried several different roms on several different versions of MAME32 (including the latest version, which is what I have now), and nothing works. It won't even recognize the zip file when I do an audit. This is one of my all-time favorite arcade games, and I'd love to be able to play it. What am I doing wrong? (After Burner II works fine, BTW, but I really want the original I grew up with.)

Thanks in advance for your help.
