Well apart from finally proving that there is games in
the original library toying with self-modifying code, it
reveals another mystery. The code that is executed in
the RAM reads:
LDA $FFF9
JMP $F669
Cool. So I guess they just modify the JMP address each time to call
different subroutines in the upper bank? How do they get back? Same way?
It's clever, but I sure can't see wasting 6 bytes of RAM for bankswitching!
