Hey, I'm just about finished with a rom manager style program that works with my frontend.
It will allow you to move roms from one to another including all additional files (images / movies / ect) and entire family (parent and all clones when selected) based on single select / category (from catver.ini and other ini type files) and any information from the listinfo or listxml from mame.
So you can move all your trackball games + dial games into a specific rom directory. All capcom games into another... And all 2player + 6button games into another.
The trouble is it currently only works with my frontend setup.
Would anyone else be interested in using it? Should I try and make it usable by others? I don't want to waste my time for something I wouldn't personally use.
