I don't think this demo will ever work in an emulator that does any kind of error checking.
It fails on interpreter because it emulates the n64's basic address checking, whereas the recompiler just accepts what is passed.
The typewriter noise fails at the start because the address cannot be translated by TLB.
This one strikes me as odd, it may actually be a failure in emulation but I can't be certain without doing some more research on how TLB exceptions work.

These are problems I can't really 'fix' since PJ64 is doing exactly what it's supposed to be doing.
I'm curious if this demo would work on a real n64, from everything I've read it should fail for the same reason it's failing on PJ64's interpreter.
