During my hacking escapades I tend to be reminded of bugs I've known for a long time. Sometimes I can find their sources and try to fix them. Here's a few guides I put together for common bugs I haven't seen fixed anywhere. How-to:Fix bugs relating to Super Sonic This is a big one. Here you'll find fixes for a whole bunch of Super Sonic related bugs, the most important one being the one where you get stuck in the air after completing a level. Most of the others are mostly cosmetic, but do make the game behave the way it was supposed to. How-to:Use correct height when roll jumping I posted about this before. Basically, when you jump while rolling Sonic might jerk upward a few pixels upon landing. When this happens you can't jump until he lands again. This one has been annoying me for a while. How-to:Fix jump height bug when exiting water This one's been bothering me ever since I was a kid. Sometimes when you try to jump out of water Sonic only jumps really low. After I finally figured out what causes it, fixing it was pretty easy. I also added explanations of every bug for your reading pleasure. This should hopefully be educational. There's more to come, I've just spent multiple hours writing these and it's really late. Edit: Next batch: How-to:Fix camera y position for Tails This one's always really bothered me and I don't even use Tails that often. The camera's vertical position is pretty jerky for Tails. The way this fix is done, no special code will ever be necessary to handle the character changing height, at least as far as the camera is concerned. How-to:Fix bug in ARZ Boss arrow's platform behavior Not that noticeable or problematic, but it's still nice to have it fixed. The arrows that the ARZ boss fires trigger the walking in air bug that happens when Sonic doesn't get released from a platform properly. How-to:Collide with water after being hurt When Sonic gets hurt he doesn't interact with the water surface. I put this one down as a design choice, since it's debatable weather the original behavior was intentional or not. The Advance series indicates that at least one person thought it wasn't.
