No more spamming teleport blocks at the bottom row of a level! Without the patch the player had to hit a teleport block at the bottom of the level and now he really has to fall offscreen similar to Yoshi's Island and NSMBW. Needs sometimes workarounds but that shouldn't be (probably) that much a problem.
Read "ReadmeOrDie" for further informations.
This version adds some SA-1 compatibility (the GIF was also taken on an SA-1 ROM), some changes in the readme and an animated 15-FPS GIF with a bad quality (yeah...) to see that I'm not lying!
