Gex (PlayStation)

To do: Document the version of the game used in Gex Trilogy and look for any changes and/or differences.

Gex was ported from the 3DO, now with improved camera scrolling in levels.

Unused Graphics#

3DO Version Leftovers#

0C1B5864.dat and 0C174235.dat

Remnants of the 3DO version's save feature (which in every other port was traded for a password system).

0C174231.dat

Sprites initially used for an animation of Gex using his tail to spray-paint the game's logo on the title screen.

Tiles initially used for the transparent border surrounding the title screen.

Miscellaneous#

Sprites of Gex's tail and what might be its shadow, both of which are never used in any version of the game. These are stored in the same file as the graphics used for the title screen. The palettes for these is unknown.
