I have just begun using Mame32.  I am deployed to Iraq with the U.S. Army right now, but when I go home in a few months I am going to begin constructing my first cabinent.  I am trying to work out the software while I am here.  Many of the ROM's I try to play give me an error ".chd NOT FOUND"  In addition, sometimes when I am playing the game will skip or switch back and forth between other games.  Can anyone help me with this?  Thanks from Baghdad!!!!!!!!!!
