I would like to suggest that for the graphic STORY9.png (graphics/intro-graphics/) be revised to use the helmetless version of Mega Man's graphic, seen here:

Also, for the music cue for the "A NEW CHALLENGER!" text at certain points of the single player campaign, I suggest that for certain chapters, play the following instead of MM3SEL:
MM1 Chapter:
MM1SELMM2 and MM9 Chapters:
MM2SELMM4 Chapter:
MM4SELMM5 Chapter:
MM5SELMM6 Chapter:
MM6SELMM7 Chapter:
MM7SEL (can't find a non-RM4FC cover)
MM8 Chapter:
MM8SEL (can't find a non-RM8FC cover)
MM&B Chapter (which, for some reason, has no music playing in the current build):
MMBSEL (no 2A03 cover for this one exists, as far as I know)
MMWT Chapter (which, for some reason, plays MMWTVIC in the current build):
MMWTSEL (
2A03 cover by E253MechaShadow)
I just always find it odd how each map uses the boss and victory themes appropriate for the games they originate from, but the New Challenger cue is almost always from Mega Man 3.
