Development:SpongeBob SquarePants: SuperSponge (Game Boy Advance)
This page details development materials of SpongeBob SquarePants: SuperSponge (Game Boy Advance).
As if the PlayStation version wasn't enough, on December 19th, 2019, a backup disc containing early source code, builds and assets from the Game Boy Advance version of SpongeBob SquarePants: SuperSponge was found on eBay and can be downloaded here.
Most of the discs' contents are from April 2001 at most, predating the final release by several months.
On the disc in the Mockup's folder are some early graphic tests.
This folder refers to artist Chris Rundell.

01 - PSXTest
A song titled "PSXTEST" can be found in /SBSPants/Sound/. It is dated 12/12/2000 and was most likely used for testing sound on earlier builds of the PlayStation version. This song is a XM remix of the original SpongeBob track "War Blowers" by the Blue Hawaiians.
01 - TITLE
In the same folder, there's an audio file titled "01- TITLE_XM". The file dates to the same time as PSXTEST, and unfortunately contains no data.
