Differences between the Prototype version (Game ID : 922804/2) and the final release :

* The Prototype uses a OKI6295 @ 8 Khz instead of the GAELCO @ 13 Mhz.

* The Prototype has a very different soundtrack, which creates a different atmosphere when playing the game (Prototype has guitar music, Final release has folk songs, such as Barnacle Bill).

* In the Prototype version there is a digital scoreboard that was not there in the final version.

* In the final release, there are no special blocks and helps.

* In the final release, when only one player plays, the playing area is centered in the screen.

* In the final release, when there is only one player playing the game, the screen has only one playing field.

* The final release is an endurance game, while the Prototype is ala Tetris from Atari, a levels game.
