Sonic X-treme

This page details one or more prototype versions of Sonic X-treme.

Multiple builds of Sonic X-treme have surfaced since its cancellation, giving valuable insight into the game's tumultuous development. A disc containing an early Saturn tech demo was discovered in 2005 and released to the public on July 17, 2007. In 2014, ASSEMblergames user Jollyroger found a set of data discs that belonged to the Point of View studio, which included early PC builds of Sonic X-treme, level editors, and an unseen prototype made by Point of View dated July 14, 1996. The PC builds only supported Windows 95 and the Nvidia NV1 video card, so Jollyroger modified the builds to render in OpenGL for better compatibility.

v53 Level Editor#

Jollyroger only has a small chunk of the source code to this editor thanks to some binary chunk files, which were enough to build a binary executable. He released one screenshot of the v53 editor running on Windows in 2014, but multiple screenshots of a similar build were previously found in the "PackageX" level archive that leaked in 2009. For many years, those screenshots were the only glimpse the public had of a later Sonic X-treme editor. It's unclear what exact features are present in the editor, however it has been confirmed that the Paths system does not exist and the editor can only load a couple of levels.

A build of this is unlikely to be released.
