It's one of the best and more desirable multicarts because it has virtually no duplicates. There's I believe 97 or 98 unique games, one is a funky dupe on accident from the looks of it, and the others are 'pro' hacks at the bottom of the list where they speed the games up to make them harder. With the retron5 tech last year the data on that cart was dug up and added officially to work on the retron5, at least the NES version but if that's got the same CRC it will work too.
