Hello everyone,
I'm currently in possession of around 6,000 ROMs, but unfortunately, I have 3,000* duplicates. I mistakenly imported two different ROM lists, which resulted in a large number of duplicates. I'm not sure what the best way to go about deleting these ROMs is. Is there a way to delete them all at once, or do I have to delete them one by one? The latter option would take me days.
Thank you in advance for your help!
