Pro Action Replay Codes
Note:
Since the Pro Action Replay cartridge has the capability
to write to memory addresses outside of the Game Genie's range,
the following codes may only be enabled with that device. It
is not possible to convert them for use on the Game Genie.
Unlimited health:
7E1407C8
Unlimited ammunition for all guns:
7E0095C8
