Proto:Sonic Heroes

This page details one or more prototype versions of Sonic Heroes.

Please elaborate. Having more detail is always a good thing. Specifically: Can anyone look further into what the exact date for the GameCube "Trial Version" demo (that is included on the Mario Kart: Double Dash!! Bonus Disc, Interactive Multi-Game Demo Disc Version 14 and Version 15) was built on?

Sonic Heroes went through a lot of interesting changes throughout development, as showcased with its whopping nine prototypes (although only the Xbox and GameCube versions of the E3 2003 prototype are available, and one, GameCube prototype 10.13, has remained undumped due to issues with the disc). Many of these are for GameCube, with two Xbox builds and one PlayStation 2 build also being dumped.

Two of these came from drx's big 2008 proto release: A demo from E3 2003, which can be found on the BetaArchive FTP, while another build came on a bonus disc containing playable demos and videos of various upcoming games as a reward for pre-ordering Mario Kart: Double Dash!!. The final few were recovered from devkits or burnt discs.
