Hello, everybody. A game developer who used to work for Odyssey Software sold me these two prototypes plus a crap-ton of other stuff for $20. I could not test these in my NES to see what games they were because the chips stick out of the cartridge and thus will not fit. I was told by the game designer that the games could either be Blackjack or Pool (Odyssey Software). Just thought I'd share an interesting piece of history with you guys!
