I'm gonna sound like a right noob, but it's something I would like to know how to do... so I'll risk it!
When checking MAME ROMs using clrmamepro, I have the main mame/roms folder and also any updated ROMs I have downloaded (in a folder called rom_updates, for example).
How do you use clrmamepro to simply check the mame/roms folder and add anything missing from the rom_updates folder?
I don't want to do a full rebuild into a new location (not enough diskspace), just merge the updates easily and quickly (currently I unpack the zips manually and add the files by hand, then clrmamepro the mame/roms folder at the end, which takes ages!)
Cheers in advance for any advice (as opposed to put downs or pointing me to the clrmamepro forum (as I'm not registered there and I bet loads of people know how to do it on this forum!))
