I've recently downloaded Mame4ios reloaded and i have put a few of the rome which i downloaded from the .139 folders on this site but none of them seem to work. i keep getting an error saying that the folder is missing one or more of the ROM or CHD images.
I'm very new to this MAME thing so i'm not sure if i need to convert the files or something.
Any help in this matter would be greatly appreciated.
