This page details one or more prototype versions of Sonic Heroes.
| To do: Document the Xbox review build, which is effectively the final game but still containing minor differences and leftovers (including the full object layout for the test level). |
Sonic Heroes has gone through a lot of interesting changes throughout development, as showcased with its whopping nine prototypes (although one, GameCube prototype 10.13, has remained undumped due to issues with the disk). 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 with 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.
