ToDo: Figure out what's really going on
EDIT: this is fun, it's in im0 and trips ei ... my best guess is that
there's a protection device enabled at 0xf000-0xf001-0xf002-0xf008 that
sends a custom irq (either ld hl,$019d or jp $019d). After the initial
code, the protection device is disabled or changes behaviour via
writes at 0xf000 and 0xf008. -AS
