With the codes enabled, press Down and Start while playing the game to make the debug menu appear. Press A and B to exit out of it.

• ENEMY CLEAR - Removes all on-screen enemies
• HIT DISP - Shows the collision detection boxes
• TASK DISP - Unknown
• GAGE MAX - Fills up the life and power bars
• MUTEKI - Invincibility
• POWER - Pressing Left and Right changes the stat select, and pressing A changes the stat. Pressing R maxes out that stat, while pressing L goes back to the most basic level
• EVENT - View a cutscene in the game
• BGM - Turns music on and off

S and P are presumably coordinates, while the bottom two options are heap-related stuff.

Regional Differences

To do: Find specific enemy and level differences; screenshots

The Japanese version was a little unpolished compared to its overseas counterpart. For one thing, it only has Easy and Difficult difficulty settings. The International versions remove Difficult in favor of Normal and Hard, with Normal as a rebalanced version of the original Difficult. The International versions also adds a health meter for the bosses, language selection, adds a couple new enemies, adjusts some of the level layouts, and fixes some of the slowdown.
