To correct this, when the background music starts, the sprite table is scanned and forcibly altered if any explosion sprites remain. I also added code so that the attract mode now plays on a random stage, and has infinite lives. Source code for the emulator is included, but it's pretty messy and contains a lot of disabled features. The intent of providing these zips is so you can see the progress of the game itself. Each should be unzipped into it's OWN directory.
All versions support arrow keys to move, tab to fire.
Original Port of SSA to dedicated emulator. Improve graphics - Add better starfield and replace sprites with polygons. Replace game win routine - frightenly easy, since it's an entire program in itself. It wouldn't be emulated anymore, but that's not a big loss. Player's ship and bosses are fragmented onscreen.
