Genesis Sonic cleanup

[Dolphman]

Sonic 1: First above the credits
Sonic 2: Second above the credits. The Master Emerald at the bottom right, though the glowing was custom made by the submitters.
Sonic 3D Blast: The CGI-looking ones ones at the bottom left
Sonic Spinball: Big blue hexagonal one between the Sonic 3 Emeralds and Master Emerald. Not sure, but I think that weird red one too.
Sonic 3 & Knuckles: Master Emerald up top, both palettes. Super Emeralds under it plus the unpowered one under them at the left.
The Tiny ones above the weird red one also from Sonic 3 as are the ones between the Spinball Emerald and unpowered Super Emerald.
Finally the Master Emerald on right with the base featured in the Mecha Sonic sonic fight which is also a separate sprite in game.

Hope that helps.
