It has some sort of function -- possibly a nibble counter -- invoked
shortly after boot.  I remember cracking it.  It used two obfuscation
tricks: it did a branch into the middle of an instruction (a BIT $xxxx),
to conceal the start, then XORed itself before and after.  Once the
check was commented out it was easy to get a clean copy.

It's unlikely you'll get a simple .NIB image to work, but it's probably
a one-byte patch to fix it.
