no, I'm using mame 2003. In hopes that I could use a later version once I got it working. I like to use the save state on exit feature to "save" my high scores, but that usually means using a newer version. If I am correct, Mame4all is based on mame .0375 or around there and that was just too old for the options I wanted.
What I have discovered is that when using retropie, it changes things versus what normal mame would use. I have read that link before and that is what I used to prepare my windows based machine. If you look at the bezel project stuff, you will see that the pi stuff doesn't follow the same guidelines as the pc version does. You are now required to have three files, your bezel.png, which uses a transparency image (like a gif), you need a romname.cfg (which basically points to the third file) and romname.zip.cfg which is where you put your bezel artwork info, which btw is also different that the link referenced.
I wish it was as easy to get working as before with the windows pc, but it ain't. I will probably just take retropie off and install a linux os and just run the game from command prompt. I don't expect to use this machine for more than Qbert, but it was nice having alot of elbow work completed by retropie setup.
