funny how this predicted the Red Rings

hmm yes crimson ring

Well, they need to be revised (I've got it lined up to upload, but there's a few more things I want to get finished first before I submit it), but basically -

Raw / Mobile Port increases in increments of 32. It's halved for Shadow (Night Mode), which increases in increments of 16, and Highlight continues the remainder of the halved increments from 128 to 240.

Rendered through Genesis - tangential increments from 52 and upwards, with just as strange Shadow and Highlight, is actually how the colors appear through the television, at least with 1990s technology. With ports like those for the Mega Collection+ for the PS2, the palettes end up being different.

Not seen on the sheet, but on some others that I've been able to revise to the current system, are the following:

Actual - rises in increments of 36, and works the same as Raw, with Shadow and Highlight rising in increments of 18.

PC Port - rises in increments of 34, and works as above, with S & H rising in increments of 17.

They're there for those who prefer any of the palette schemes that aren't used on the sheet, as a sort of catch-all "Here's your option if you want it".

What do the palettes that are concived through numbers supposed to clarify?

Don't get me wrong, I appreciate the error-highlighting. The request is more universal, it just happens that you were the only one to point it out. I'd rather the comments be more pertaining to the content's context, instead of "hey there's something wrong here".

Oh, okay, I'm sorry for not PM-ing you.

Fix submitted. I'll deal with the icon later.

I know I limited it to the Sonic sheet, but can I please be PM'd over all my sheets' issues from now on?

The Game/Time Over text is actually the Sonic 2 Sprite, but with the Sonic 3 palette and looks incorrect (and creepy!).
