Proto:Mario Superstar Baseball

A demo of Mario Superstar Baseball (at this point, Mario Baseball) was released on Interactive Multi-Game Demo Disc 27 in January 2005, well before the Japanese final was released on July 21.

Title Screen
The old logo is completely different. It represents baseball more than the final's logo, but the final logo is more vibrant and Mario-ish.

Music
Some songs are a bit different at this point in development.

The title screen music is very slightly different. The final has more depth and instruments to it.

The victory music sounds more triumphant in the final.

The results music sounds a little more MIDI-ish in the prototype.

GCM Information
The following can be seen by converting the demo to an ISO and placing it in the Dolphin (GameCube/Wii emulator) menu.

First of all, the game has its own save banner.



Secondly, the internal title reads: "Famista2003 GC" ( ファミスタ2003 GC ). This would appear to refer to Namco's Family Stadium 2003 ( ファミリースタジアム 2003 ), which was released for the GameCube on May 30, 2003.
