Can you show a listing of the ROM folder on the Pi, where you copied the arcade ROMs ? If they're not in .zip format, then they will not show up.

I have managed to code backgrounds, system images etc, I just can get my head around the carousel editing. I have found some coding relating to carousel changes but when I add the text to the XML document it doesn't seem to do anything. Do I add it to the theme XML in each separate system or do I add it to the spare XML?? It may just be that I haven't entered the coding text correctly or I have put it in the wrong XML.

@BuZz I'm sorry just delete my posts I'm an idiot... sorry for bothering you people
