Unused Graphics#

DUMMY.BAC#

A seal animal buddy leftover from Sonic Advance. It's different from the one used in-game.

AC_ENE_TENTO.BAC#

A complete animated sprite set of Sonic Advance 3's Akatento and Aotento badniks, seems to be a leftover from that game. The transparency is also broken. It should be noted that it's found alongside the final game's enemies.

Ending Sketch#

Occupying an unused entry in Sonic's ending artwork is a rough version of the last artwork from Blaze's ending.

Boss Fights#

Every boss map has a normally unseen 2D level that is used for collision and items for the boss battle. The example to the left shows the Level z13 (Zone 1 Act 3). Trying to load these levels as a non boss fight level will have various glitchy effects.

E3 Leftovers#

Found with the other graphics, and helpfully prefixed with "e3" are these images. They can be seen in the E3 demo. e3_comsoon_jpn.bbg is a bit more descriptive than the _eng version, and says "Thank you for playing. Play the retail version to see what comes next!".

Unused Music Portions#

After the Fight

Kick the Eggman

Sonic's and Blaze's respective Boss Defeated themes are normally cut off after around 7 to 12 seconds, but are actually about a minute and 30 seconds each. They are not featured in the official soundtrack, but can be played fully in the Sound Test.
