We’ve all played Sonic Heroes at one point. I’m sure at that same point we all heard the music in the game too! What you may have not known is that more than one Sonic Heroes prototype has surfaced to the net at some point. The differences ranged from minor to relatively major, but one part of the game in particular that recieved some interesting changes were the music. Now if you know me, you know this is totally my thing, and I was pretty excited by some of the changes I heard. Here are three of the tracks I found the most interesting of them all.

For many players, the Special Stages of Sonic 1 can be particularly frustrating for a number of different reasons–rotation, steering, and jumping are the most common reasons listed. Forum member Mercury, best known for the Sonic Physics Guide and Sonic: The One Ring, examined the stages and realized that Special Stages don’t have the variable jump height present in the rest of the game. He investigated and found there was an unused routine for reducing Sonic’s jump height in the Special Stages within the code of the game. Using the power of trigonometry, he repaired and enabled the routine, leading to a fix that combines the X and Y speed using cos and sin to find how fast Sonic’s moving upward at the current angle in a Special Stage. It compares this combined speed with the jump release speed ($400) and if it’s greater, then it uses similar code to the normal jump to make Sonic move at $400 in the current angle. Simple.
You can read more about this fix and download a patched copy of the game at the Sonic Retro forums.
Forum member and resident wiki sysop Andlabs has been very busy tearing through the Knuckles’ Chaotix ROM recently for the sake of documenting its internals entirely. Among the oodles of information he’s uncovered, though, one particular find stands out…
It’s Tails in the Tornado! It’s been known that Sonic and Tails had leftovers in prototype builds of Chaotix, but something of this caliber has never been seen before. Big props to Andlabs for the find!
