• The 5200 version (picture #1) is basically the 400/800 cassette tape version with the change of fully supporting analog controls, whereas the 400/800 disk version (picture #2) included everything.  Besides the different copyright info on the title screens, the 5200 version is missing the high score (save) screen (picture #3) and scrolling message opening screens (picture #4).

• The Flag Ship never gets any lower, unlike the arcade version.  It also doesn’t shoot faster the longer it’s onscreen.

• BUG: With the Flag Ship, you can shoot away all the parts of it except the core, indefinitely (picture #5).  If you remain on this screen long enough, the color cycling will start (picture #6).  This can be cancelled by pressing any of the keyboard keys.
