Sonic 1 Special Stage Jump Issues Fixed Nearly 20 Years Later

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.

SAGE 2010 Extended Through Tuesday

Haven’t had the chance to pop on over to this year’s Sonic Amateur Games Expo?  Well, you’re in luck.  Katzu Niku and InstantSonic have announced an extension through Tuesday, known by most of us regulars as the annual “SAGE Hangover.”  I believe this year’s hangover is the first “scheduled” one.  Usually, we leave all the shit on and there just happens to be people still chillin’.  At any rate, we’re still partyin’ like it’s 2000 up in this bitch.  All the booths are up, the chat is still open and the SAGEcast is still jammin’.

One thing is for certain… there will be more Sonic Fights Robotnik fan fic readings! I’m sure David the Lurker just wet himself again.  That’s the seventeenth time in the past week.  To prove how epic these readings have been, here’s a clip of Mike Pollock, the voice of Dr. Eggman, reading a line from it.  Yeah, I know.  Awesome.

All hail Tankbot.
