I had to remove intro/splash screen from FastROM hack to get MSU audio to work.
If you should happen to read this Linkuei; I'm terribly sorry, it's a nice splash screen, so my apologies in advance.
Apply patch to clean headerless US rom.

Not thoroughly tested but it seems to be playing along perfectly well as far as I can tell.

[edit]
Patch cleaned up, excess data removed and internal header fixed.
