The sfg-* directories have both my (Piers Bell, aka. Crash) and Dave Surridge (Zordon)'s unfinished code for our joint, multi-genre project; Star Fleet the Arcade Game. 
There's also a 99%-playable executable of my levels. 

It really was a stellar game. We just didn't have time to finish her. So, I'm re-creating much of it in XB2. Our development cycle was actually very awesome as our project was practically always demo-ready. All the levels that we started are all complete and playable.

In the root directory, are the three released versions of xb1; Star Fleet _ X-Bomber; v0.9, v1.0 and v1.1.

The xb1-* directories contain the source code from all stages of development, installers and standalones for all released versions and 2 very early compiled versions from as far back as August 2002, the Vitalize plugin version and the MIDI music used in the game.
