I just received Teleroboxer on Virtual Boy. I kinda ordered it by error, but it was probably the best price I found for it online anyways.
Actually, by coincidence, I just got ANOTHER game involving boxing robots, Real Steel on PSN. Haven't seen the movie, don't really plan to, but the game is actually pretty good. It's a lot like Fight Night in regards to the gameplay mechanics (somewhat close to Round 4 I'd say, but with simpler controls and less depth), with more customization for your fighter (you can mix and match any parts you want for head, arms, fists, body, legs, and a couple more). The battles aren't mindless button-mashing and are generally fun. Very solid for a 10$ game.
