I do wonder how compatible it will be with expansion chips (like the DPC in Pitfall 2). I assume they have an internal list of recognized games, but I wonder what happens if someone wires up their own homebrew game with one of those chips and plugs it in?
But you're right, I should have mentioned it because it's a good idea to do and a legit product, I just had it purged from memory because I wasn't interested in it.
