Konami have confirmed that the digital re-release of The Simpsons Arcade Game is due out on Xbox Live Arcade this Friday for 800 points. The game has previously been confirmed for release on PSN on February 8 with PSN Plus members eligible to pick the game up for nothing!
On a personal note I remember playing the arcade original during a vacation to Lanzarote, and for some reason the machine gave me infinite credits. Naturally, I did not want to leave my station and was finally dragged by my dad as it was time for lunch.
