A set of RAM addresses used to determine the horizontal static camera region, which defines the size and position of the area in which Mario's movement should not cause the screen to scroll horizontally. There are three different 16-bit values involved in this:
- $142A: The origin position of the region.
- $142C: The left edge of the region (by default equal to $142A - #$000C).
- $142E: The right edge of the region (by default equal to $142A + #$000C).
It is worth noting that writing to $142C/$142E will not actually do anything, as those values are automatically recalculated every frame (at $00F6E0).
