Proto:Digimon Adventure (Game Boy Advance)
This page details one or more prototype versions of Digimon Adventure (Game Boy Advance).
The ROM of this game surfaced via a private Chinese forum and is believed to have been leaked by a former Sintax staff member.
Unused Levels
The game has all four levels and both bosses from the SNES version (albeit in a different order), but since the first boss can't be defeated it's ordinarily impossible to progress beyond that point.
By modifying memory address 0x03005000 (CodeBreaker code 33005000 00??) to one of the following values on the stage intro screen, you can access any area, including the ordinarily inaccessible ones:
- 00 - Stage 1
- 01 - Stage 2
- 02 - Boss 1 (uses "Stage 3" intro screen)
- 03 - Stage 3 (uses "Stage 4" intro screen)
- 04 - Stage 4 (glitched intro screen)
- 05 - Boss 2 (glitched intro screen)
The game only has title graphics for Stages 1-4, but includes boss stages in its numbering, leaving Stage 4 and the final boss with glitched intro screens. This is fixed in the released versions.
Value 07 or higher loads the ending. 06 loads a glitchy area, presumably loaded from non-level data, but the fact that it loads at all and doesn't skip directly to the ending may indicate an intent for another stage.
Title Screen Music
This prototype attempts to play song 21 on the title screen (as heard in the released variants), but fails to do so. The code is seemingly still expecting a single sample at this point.
Debug Code?
Pressing Select + Start during gameplay sends you directly to the continue screen. This is useful if you get stuck somewhere, which you will.
This behavior is not found in the released versions, which implement a pause screen on Start.
