asm hacking: "faking" short jumps from your code (in a new bank) to old code

The following code allowed me to call a $C2 routine while being in bank $EE. Not the best example but it proves it works. Just enter the battle and set breakpoint at $C20CB0. I'm including the debugger console log. I never touched "step over" or "step out" except one "step over" at $C20D42.
