Ah .. such a nice game to play on the Bitbox ! (see Angry Video Game Nerd or Joueur du Grenier reviews ;) ... )
This game / engine is aimed at reproducing the dragons lair game on the Bitbox. It's only compatible with the standard bitbox since the data is streamed from SD card.
It's currently 200LoC / 40k flash / 128k RAM + a 70MB data file
