This shows how many exits have been found in the status bar. The counter position can be changed. Contains two patches, one for 99 exits and under, and another for 100 and up. Credit to Ice Man for the original patch that only went to 9.
Tested with: Asar v1.71; SA-1 v1.32; Lunar Magic 3.04; snes9x 1.60
This patch is up to the standards and requires no remoderation. Added screenshots; as you can see, it's better if you tweak the position of the rest of the counters a bit.
