Perfect, thanks for the replies!
Another quick question, I can mount ext drives on my Mac, so I can edit files on the main retropie partition, with this in mind, is there anyway I can manually replace / edit scraped data?
Some of the games I have scraped have the incorrect pictures or can't find data at all, so I would like to manually create / edit some of them.
Is this possible, and if so, where are the files?
