Similar to the specific screen teleport blocks, this vertical pipe will teleport you to a specific screen exit. It can also be set up to teleport to a different screen exit depending on a condition, such as the P-switch being active, the number of exits collected and much more.
Make sure to edit the settings file and keep it in the blocks folder, but don't insert it directly - only insert the left and right blocks.
Tested with: Lunar Magic 3.20, GPS 1.4.1, SA-1 1.32, Snes9x 1.60.
The update only moved the |!addr flag define from the code to the definition, so I did some quick tests and it seems to work fine. Only oddity I could find is that bringing an item through the pipe will make it spawn at a different position than Mario after the transition.
