There are unused strings located among the cheat/debug menu text block.

These likely refer to specific options in the menu:

 * DEBUG
 * KEY REC

This likely refers to the "gunner" option:
 * THUNDER

 * 3WAY  
 * UP DOWN
 * DIR8  
 * GRADIUS

There also appears to be some text allowing you to turn the debug mode on and off.
