The rom is in "bank 15" & it manages to reset from it.

I don't know what that corresponds to in p0-p3 & $0, the datasheet is a 
bit light on details. It says p0-p3 is 1 during reset, but that could 
just be while reset is driven low.

I guess you know though, if you're able to reset when in emulation mode.
