A prototype of Tiny Toon Adventures: Babs' Big Break for the Game Boy.


  • Early prototype.
  • Japanese prototype.
  • Boots right to the Konami logo in this build. In the final it boots to a trademark screen.
  • After the Konami logo it goes to the title screen. In the final it goes to the intro.
  • The intro hasn't been implemented yet. Instead a screen with the text "TITLE DEMO" is in its place in this build.
  • No music on the title screen. Pressing start doesn't play the jingle like in the final.
  • You can press start to skip all the dialog in the prelevel scene. You can't skip all the dialog in the final build.
  • Different title screen. There's a PASSWORD menu that doesn't appear in the final.
  • Slightly different music.
  • You start off with four carrots in this build as Buster Bunny. In the final you start off with 3.
  • There's a time limit in each stage of the game. The time limit was completely removed from the final.
  • Different stage layouts and designs.
  • The Pause menu includes a REST count that was removed from the final.
  • Gold coins instead of diamonds for pickup items.
  • You start off with three hearts of health rather than 2. This is seen in the Japanese final but not the US one.
  • The wooden stumps that you can press down to go underground are pipes in this build that lack the down arrow.
