Any progress for spawning the big rings in debug mode? is it even possible?
Sorry, I don't think I'll add special stage ring spawning to the debug mode at all. Haven't had a look into it, but I can imagine this could get tricky.
or add the emerald special stages to select mode?
I'm having plans on something like that, but don't want to spoil that yet.
I keep saying over and over though
a way to re-access the emerald special stages would complete the mod.
Made a change with today's update: Let's say you played through the game and the Chaos Emeralds traded in for the gray Super Emeralds, but don't have all Super Emeralds yet. Then any Giant Ring throughout the game will take you to Hidden Palace, including all from the Sonic 3 zones. As I understood you, that's the case in your save game. So maybe that helps?
I Defeated the Underwater Enemy, But the Achievement Isn't Showing Up.
The enemy has to be killed by the electric flash in the water caused by the lightning shield entering the surface.
Is there a way that you caould add eggman laugh when he appears or hurts you like in the rest of the classic games?
Since they removed that detail for some reason (space I guess)
Also, what about unused stuff (like knuckles unique switches for AIZ and CNZ, eggman's defeat launch base animation, knuckles laught in lava reef act2, Eggman's unused head in Flying Battery, Sonic's full waiting animation and Super Sonic idle)
I actually like that idea, because I can well imagine it's something the developers left out for technical limitations only. But I need to check how much trouble it will cause if I try to integrate the animation.
However, that's certainly no high priority. (And it would be optional.)
