| iNES 180 |
INES Mapper 180 is used to represent an unusual configuration of the UNROM board used only for the game Crazy Climber.
It is similar in principle to the more common INES Mapper 002 configuration but uses AND logic (74HC08) instead of OR logic (74HC32), producing a fixed first bank at $8000 rather than a fixed last bank at $C000.
Crazy Climber had a special "climber stick" add-on that mounted a stick on top of the Famicom's directional pad.
For a similar mapper with additional mirroring control, see iNES Mapper 097.
