For the life of me I cannot get the artwork to display in mame32 or thru a frontend such as mamwah.... one example is battlezone...... In mame 104 if i zip up the bzone.art and launch the game my monitor goes out of range... (it's a D9200). It seems to ignore the zipped up bzone.png file... Is this because of the resolution of the artwork? Does anyone know a good site thats explains artwork/bezel use in detail?

I have searched and not found much on this subject..
Thanks in advance!
