after catching several rom packages I know that I have a lot of dublicate roms with (sometimes) different naming. to test, check and delete thousands of games I would like to ask the group here if there is a rom manager out there for i.e. NES, SNES Games etc. to make the checks if there are duplicates. in my dreamy visions I see a tool that would go into the 7z or zip file, check the MD5 checksum put it in a list and after scanning all roms it would then check the checksums and shows me the duplicates. so that I have the chance to delete one or another etc. also with the possibility for renaming it in a batch like way.
does someone of you are using something like that and give me some recommendations?
best regards,
me
