Puzzle Piece Panic
Well it's finally out, Tetris on the odyssey 2... and it's very, very solid. It even plays polyphonic music (an O2 first) when the games over (guess the O2 couldn't handle music with gameplay). Here's the link http://www.packratvg.com/ppp.html.
I still think you should review Shark Hunter or Spider Man for the O2, or maybe even Mission Impossible... They are all from ROMs of games that never came out.... A limited number of those carts are being made but I bet there are a few potential buyers who peruse your site... Tutankham on the O2 rocks, but I don't think you can get a cartridge...
But Tedfoolery, maker of Mr. Robota and Puzzle Piece Panic, reports he'll be coming out with "Pick Axe Pete 2" soon... I hope you are excited despite your severe underrating of Pick Axe Pete
