It's very possible the differences were really there in the arcades. Given the way MAME works, I don't think there can be a such a difference between audio that much if it were not explicitly coded into the game. Wikipedia has some observations between Japanese and US version - they all seem valid. So many differences lends some validity to the fact that the music was intended to be like this:

I'll confirm pending some input from Devs in the know - I am leaning towards this not being an actual bug.

I'm pretty sure something is wrong here.

Loading the sound ROM in a different arrangement produces sound and music almost identical to the Japanese version.

We need somebody with an original PCB to verify this.

I'm nearly 100% sure this is an incorrect dump or an incorrect loading, do we know who supplied the original dumps for this one?

Took some digging, but: Yasuhiro Ogawa uploaded the Marvel Land (US) back on January 1st, 2000 (verified). Because he was often cooperating with/was part of Team Japump, he may not have been the dumper per se.

Nope, still needs verification. All that research is done with emulation.
