The above text is a very abridged overview of the artwork source and how it works according to MAWS. There are plenty of other nifty tools you can use for artwork, but you probably won't need.

Use simple deduction to determine how different commands work and make then make your own. If you have any specific questions after that, send me a p.m. If you meet any success, please submit your new artwork file to mame.net for inclusion on their artwork download page. Also the AI files you want to use for mame must first be exported to the png format...That is the only format that you can use for mame.
