Romcenter

Hi, i have 6000 NES roms, but the more of them are duplicates for example

smb.nes
smb[h1].nes
smb[b1].nes
smb[b2].nes
smb[b3].nes


i only want ONE smb rom, and like this with all the games

RomCenter can help me to remove duplicate roms?

These are not duplicates, but alternates roms. Files are differents.
If you want to remove them, you can try to find a new dat, or edit your original dat file and remove all games with (hn),(bn)...
or you can filter and remove the files in romcenter: enter [h1] in the search field and remove all files displayed. Repeat for [b1] etc....

People, I'd recommend using this photo duplicate remover to deal with unnecessary files on your hard drive. It has many functions, user-friendly interface, safety options and 100% efficiency.

This "photo duplicate remover" won't help you with roms. Roms are not photos.
Roms are zipped and some games have several identical roms which should not be removed.

I just finished downloaded 1.61 GB worth of snes rom, and i already have about 1.3 gb roms. How can I remove the duplicates.

Split them in several folders
Rename all of them
Put them together
Removing dups

Another solution is to use the new 'one game one file' feature. This will remove all clones, keeping only the main games.
To activate, go to preferences/gamesset and select the check box.
All clones will appear as 'unknown'. You can them move them to another location, keeping only one fil eper game.
