[Solved] Can anyone with SPC700 experience tell me why my SPC loader doesn't work?

I've been reading up on the SPC700 and I have a pretty good understanding of how it works. So now I've attempted to create an SPC player but I can't get it to make any sound.

I've followed this example program and my code is pretty much exactly like the example program you can see here:
https://en.wikibooks.org/wiki/Super_NES ... 0_programs

I can upload the SPC file to RAM successfully, successfully load it into SPC RAM, successfully make the SPC Init code and successfully restore the DSP registers just like in the Wikibooks example, but I just can't get any sound.

I've included the assembly files in the "SPC_test_files.7z" file. I've also included the rom below.
