I don't think I understand what you mean. The bank bytes are fixed
on the tape. How can you have calculated bank bytes without writing
a completely new loader BIOS that ignores the bank bytes on the tape?

Is this just a bad example or can you really load something into
the ROM area? (Bank 3 must be the ROM, since banks and pages are
counted from zero. At least the bank bytes in makewav, where I got
my information from, indicate that.)
