Use Wii-Mednafen instead of Wiirtual Boy, it's faster.

I find it absurd that you're not giving me free waffles.

Mednafen's VB emulation is not CPU-timing-accurate, and it was not designed to be CPU-timing-accurate, for performance and other reasons(it runs code faster than the CPU on an actual VB, mostly due to lack of wait state emulation and lack of register hazard pipeline stall emulation or whatever it's called).

It's not VIP draw timing accurate either, but that was a bit more due to lack of test data.

IIRC(and I might not be :p), there is a small penalty for branching to an address not aligned to a 32-bit boundary.

There is no way Mednafen's VB emulation is going to run anywhere near full-speed on something like a PSP.

Would anyone be able to record Music 01 in its entirety from their VB and upload/link to it here?

You can bypass the simple anti-emulator check in Mednafen's debugger if you know what you're doing, but you probably don't want to do that because it sounding like crap due to noise emulation deficiencies kind of ruins the experience. ;)

Partially-unrolled loops operating on multiple 32-bit units per iteration will most likely be faster than movbsu for your use cases here.

As in something like:

uint32 
*ptr BLAHBLAHBLAH;
uint32 *ptr_bound ptr length_in_32bitunits;

while(
ptr ptr_bound)
{
 
ptr[0] = 0;
 
ptr[1] = 0;
 
ptr[2] = 0;
 
ptr[3] = 0;
 
ptr += 4;
}

Are drawPoint() and abs(), and all functions they invoke, inline?
