Ultimate Screen Teleporter v2.1

Accepted.

Note about an edit made to the patch: Show/Hide

The update as submitted attempted to merge code that was duplicated between the "exit left" and "exit right" routines. On its own this is good practice, but the code that actually activates the exit was only reachable when exiting left. Right-screen exits didn't activate a warp and caused glitches until the level was reloaded. This oversight has been corrected, please be sure to always test the final file you plan to submit before submitting.

Tested with Asar 1.81, Lunar Magic 3.40, SA-1 1.40, Snes9x 1.62.3, BSNES Accuracy 0.7.1.

I tested on LM 3.40 and doesn't seem to detect the secondary exit and goes straight to level 0.

So, how does the UberASM part work for the insert since I tried both the tool and patch and I still see crash at the very beginning of starting the ROM.

What is the !LevelNum variable? If I want to do this transition in more levels, will it work?

Tested With:
-Lunar Magic 3.33
-UberASM 1.5
-Asar 1.81
-bsnes v115
-SA-1 1.40

Fixed an issue where the range end values can't be used for teleportation (for example secondary exit 1DFF which is the last default value for bottom exit) since the check is for more OR equals. Changed default FreeRAM addresses, and added !bank define. Lastly, I added a few line breaks to the longest line in the readme for better readibility.

Aside from that, the only things I noticed are:
-In vertical or vertically oriented horizontal levels, the bottom exit will only work if the screen below has exit, (for instance the level is vertical (level mode 0A) and is 0C screens long, but won't teleport if the exit set at that last screen, if 0D is set it works correctly, or in the case of exlevel with horizontal level mode = $1B, for example, setting exit and dropping at screen 0 won't work, but will work if the exit is set at screen 2), with exception of the very last screen of the level. I don't think it's a big enough issue, but something to note.
-Side exit teleport doesn't play a sound effect, would've been similar to Yoshi's Island.
-Side exiting with yoshi won't display yoshi's entering animation, the player will just slide awkwardly. Also, yoshi doesn't get the same priority as the player, and will appear above objects regardless of !RemovePipePriority.
-!RemovePipeCenter is mentioned to rely on GHB's player trigger patch, but making it check for freeRAM (something that !RemovePipePriority just below actually does) seem to work just fine without that patch, not sure what's up with that.

Does it trigger even when using screen wrap? Just wondering.

Does this implement into normal level data or does only affect the level exit sprite? I.e. do all the levels have escape enabled edges by default after patch or only effective according to the patch and/or sprite routine in vanilla?

Just one note: in the changelog, it says 2018.

It's working quite good and I find it quite useful for puzzles!

I've changed some things in the .asm file:
- The ASM file was using "+!SA1Address" instead of "|!SA1Address", the firts one could lead to some strange results if the user uses an automatic converter with this asm file.
- I added a detection for UberASM, the patch will now throw an error if UberASM's LevelASM hijack is not found (it detects the patch and the tool). The Old LevelASM isn't supported.
