So there's a glitch that allows tails to play half of emerald coast. So is it possible to execute the glitch and run from the beginning of the stage until the games kicks you out of the stage.

Yes Im sure most people here have witnessed this glitch, As much as I know I think as of now its useless to runs.

Only would be useful if there was was a category for “All normal+Glitched stages”

There's also knuckles in Emerald Coast and Twinkle Park too, so maybe

Or It can be part of level leaderboards

It would be better to be in the SADX Category Extensions leaderboard

Yeah, that sounds like a good idea

You can also get Amy in Emerald coast.
