    Meh, I thought this was pretty weird. Sonic appears to be stuck on an invisible slope and can walk up and down it. Not quite sure how this happened.

    Geez, all he needs is an armband with a swastika and a 20-foot-tall statue of Hitler. :v:

    Those exact same bugs also happen in Sonic 1.

    Well, I remember it happening to me in Scrap Brain many times, not sure if it happens in other levels.

    Care to share a save state if it ever happens again? Relative to my interests.

    I can't try that savestate since I don't have Sonic CD with me right now, but if it's what I think it is, there's a flag that essentially can make Sonic "float." I can't remember right off the top of my head all the things it was used for, but I can say that it is used to make him lean over a ledge without falling. I played with the flag a lot in Sonic 2 savestates when I was writing the player code in ProSonic. You can set the slope value, and Sonic will be stuck at that angle, even though he's not even on a platform.

    Anyway, my guess is the saw turned the flag on when you hit it in order to bounce Sonic backwards, but for some reason it didn't get turned back off when Sonic landed. It's hard to say exactly what caused it.

    Ice Cap Zone in Sonic 3 (& Knuckles) has the same thing, caused by Tails breaking an ice block while you're standing on it.
     
  11. How did the glitch I would like to know but first after I try the save state.

    He mentioned in his post that he doesn't know how he did it. Saxman's theory is plausible, but unconfirmed in the situation presented. Also, please try to use some proper grammar.

    Gee makes you wonder if Sonic CD was built from Sonic 1?? :specialed:

    I've never had this happen to me in Sonic CD, but happened a few times in Sonic 1 such as the MZ blocks mentioned earlier.

    Im sure it would use the same base engine. You know, save budget wise. It would be a bad move not to share base code financially.
