So i've seen images and even talked to people who own legit gen 3 distribution cartridges, or consoles ig since they seem to be attached but i was wondering if anyone had a list of what carts there were or where the best place to hunt for these are. I've yet to see any on ebay

Ok so i know there are some form of gen 3 carts, or consoles with cartridges built in and i was wondering where the best place to get them are. I don't really see any on ebay and i was wondering if is like a list of the types of carts that exist
