Sonic the Hedgehog 3 is a 1994 platform video game in the Sonic the Hedgehog series for the Sega Mega Drive/Genesis. It was developed in the United States by members of Sonic Team working at Sega Technical Institute, and was published by Sega, debuting worldwide in the first half of 1994. The game is a sequel to Sonic the Hedgehog 2 and follows on directly from the end of the game, in which Sonic defeated his enemy, Dr. Robotnik; crash-landing on a floating island, Sonic encounters new character Knuckles the Echidna, and must once more retrieve the Chaos Emeralds while also working to stop Dr. Robotnik from relaunching his ship, the Death Egg.

Problems

Slowdown in Special Stages

During the "Collect the Blue Orb" Special Stages, the game will lag when a lot of orbs are on screen. This is a fault of Dolphin's emulated CPU not matching up perfectly with the Wiis. Changing the "emulated CPU Clock" to ~140% will fix the slowdown.
