Romcenter

Hmm, ok, thanks. I've now downloaded at database file, a mame superset, but where do I put the .dat file that RC will be able to use it?

Hi there. RC3. I’ve been involved in emus and roms for years, but I’ve taken a break from it for a few years, and it seems some things might not be the same.
I do understand fixing a rom, such that in the case of Neo Geo or Mame and they are made up of zip files that contain several smaller files ...

I do not know how to use RomCenter, I would like to. Is there a tutorial on how to use this program?
