These are screenshots of games that are in-progress or that are unfinished.
Here are some comments from Steve (Gorfian), the homebrew programmer of Astro
Invasion, Gorf, UFO and WarBirds:
[WarBirds is] actually a mixture of Gorf, Phoenix and Demon Attack with a few
twists. The Bally does not handle a lot of objects real well though so it
won't be as good as the 7800 version. None of these are really that far ahead
to make it worthy of a video, plus it's running off an emulator and there
really is no good way to make videos from one that I know of, or at least that
I am capable of at the moment.
Steve has no plans to finish any of his Bally / Astrocade games, nor does he
plan to release the unfinished ROM images or source code. To read a local
