[comp.sys.amiga.hardware] Amiga Action Replay Cartridge

Hi Netters,
	I have recently bought an Amiga Action Replay MkII Cartridge, which
	quite excellent.  Does anyone know how it works?  It seems to use
	the CIA registers for something or other... for example when you
	execute the following instruction: TST.B BFD100 the cartridge will
	restart the ``frozen'' program.  Could it be taking advantage of the
	the OVL (overlay) bit in CIA-A ?  And for some reason you can't
	find the cartridge code in memory (it should be a $E8000 or close).

	Anyone got any ideas/comments ?
