Hi, I'm new to this site and I just discovered how to edit starting points (wich some people already know, but I'll put it anyway). You must have at least a basic knowlege of hex to understand this.

Enter the stage you want. Get the XYZ of where the new start point is going to be. Close the game, then open sonic.exe in a hex editor. Look at that list down there and find the offset for your level. Replace the old XYZ with the new one. Save and test. It may crash if you didn't do it right. Plaus, after the X, Y, Z coordinates, there are 4 more bytes that set the character's rotation. The first 2 have the Y rotation, and the other 2 have the X rotation. Note that you edit the Unsigned Short, not Float, and It's stored in BAMS format (degrees x 182 = BAMS)

So, it's basically find the coordinates in sonic.exe and replace then. It worked the first time I tried.

This list here has the offset in sonic.exe (in hex, not dec) of the X value of the starting point. Press Ctrl+G to find it. From it, you can find the Y and Z.

Not bad work - a neat little tidbit you might want to know is that all of those coordinates are stored in an array near eachother in sonic.exe and they even have the character, level, and segment designations in the array. I don't have a technical readout of that info at the moment but if you study the data for a little bit it might become apparent
