Debug Menu Remnants

Also in the game's .ELF executable are several strings from a texture viewer function, starting at offset 0xB2340.
The first set of strings reference an old version of the game's filesystem; some of the files listed no longer seem to exist. They were meant to be displayed in a selection menu:

staff.dat
glevel.dat
sound.dat
keysize.dat
test.dat
train.dat
stagefailed.dat
msel.dat
main.dat
system.dat

The second set of strings are for the texture viewer itself:

(%3d, %3d) : TEXTURE %03d
SEMI  : %d
ALPHA : %d
RGB   : %d
W, H  : %d, %d

Note that while those screens can be accessed, they are non-functional, as there is no code for the cursor position, controller input registers, and texture pointers.
