A set of stage names stored at 5831, which appear to have been intended for a practice mode menu. The 'lasts' refer to the stages of each member of the Orochi team and final boss Orochi.

Debug Menu#

Some options appear to be non-functional. Similar to other menus, it is stored as a list of subroutine handler offsets at 7aa5, and entry text at 7ac7.

To load this menu, execution would likely have to take the jump at 2077f6 with A=0xa, instead of loading other screens (e.g. intro sequence) by taking the jump at 2077f1:

002077ee c9 cf 09        cp         A,0x9
002077f1 67 0f           jr         C/ULT,LAB_00207802
002077f3 c9 cf 1a        cp         A,0x1a
002077f6 67 02           jr         C/ULT,LAB_002077fa
002077f8 21 09           ld         A,0x9
                     LAB_002077fa
                     XREF[1]:     002077f6(j)  
002077fa c9 ca 09        sub        A,0x9
002077fd 44 a5 7a        ld         XIX,offsets_debug
         20 00

We can force the menu to load with the following patch, which makes the first jump goto 2077f8, and replaces the stored literal with 0xa:

0x77f2 = 05
0x77f9 = 0a
