Unused Graphics

Green Square

A little 16x16 green square, found in Emerald Coast Act 1's foreground assets. Not much information can be gleaned from its visual appearance, but its internal name is "test".

E3 Demo Leftovers

To do:
Bottom screen, the rest of the E3 leftovers.


A bubble that reads "Coming late 2011" that was used in the E3 2011 demo build at the end of the demo.

1990 Label


A 1990 label is stored among the collection room assets. In the collection room, year labels are used on box arts, but because no Sonic game released in 1990, this goes unused.

Debug Fonts



"DebugFont" and "DebugFontTerminal" are stored in the System directory. The font normally used by the game is named "system_font_12_03", and is located in a separate Font directory.

Unused Models



This model can be found in the System directory alongside other test files. It's a simple sphere with large markers denoting the 3 axes (x,y,z).
