General

  • The graphic transition between rounds is messed up.

  • The static in the background is gray instead of brown. It was also reduced from four colors to two.
  • The text at the bottom of the screen uses a completely unique graphic and font.
  • The space for the text was also expanded vertically.
  • Pressing Start goes straight into the game; no "1 PLAY START"/"2 PLAY START"/"OPTIONS" menu.

Ranking

Text

Text displayed after completing a boss level.

As with the original arcade version, one of these messages will appear at the bottom of the results screen after completing a level:

$ NOW YOU LOOK OUT.  
$ GO FOR YOUR GLORY. 
$ YOU LOOK LIKE BRAVE
$ONE.                
$ NEXT STAGE IS NOT  
$EASY.               
$ NOW TRY NEXT STAGE.
$ YOU HAVE REPRESSED 
$THIS EPOCH.         
$ NOW YOU GO TO NEXT 
$EPOCH.              

The text was removed from the final release for some reason.

Levels

All of the stages in Rounds 4 and 5 are unfinished. The background graphics are largely complete, though lacking in animation and collision detection. Enemies have not been properly placed; typically just a single glitched enemy appears in the upper-left corner of the field. Killing this enemy completes the level.

The game will crash after finishing Round 5, Stage 6, making the game unbeatable.

Round 4, Stage 3
Prototype Final

The alternate exit on the right side of the field was removed. Some pixels in the top corners of the arcade machines were edited. However, tiles for the arcade machines at the top of the field somehow became misplaced.

As an aside, the arcade machines featured in this stage are Racing Hero (top-left), After Burner (bottom-left), and G-LOC: Air Battle (bottom-right).

Round 4, Stage 6
