Sonic and the Secret Rings

Sonic and the Secret Rings is a video game developed by Sonic Team as part of the Sonic the Hedgehog series. It was released exclusively for the Wii on February 20, 2007 in North America; March 2 in Europe; and March 15 in Japan. Secret Rings is a 3D platform and action game whose plot follows the series' main character, Sonic the Hedgehog, on a quest to stop an evil genie named the Erazor Djinn. The game uses a system of experience points and levels, as well as special moves.

Scaled EFB Copies modifies some special effects
Having an internal resolution above 1x Native and having Scaled EFB Copies enabled will cause some depth effects (such as the text on the parchment in Lost Prologue) appear slightly different. In the case of Lost Prologue, the text disappears slightly further away than it would otherwise. This is barely noticeable and does not impact gameplay at all.

Emulated Wii Remote
Using an emulated Wii Remote may cause issues with actions such as homing attack and walking backwards. This can be corrected by marking both "Sideways Wiimote" and "Upright Wiimote" on the Wii Remote configuration screen. "Upright Wiimote" may need to be deactivated for some sections, such as the flying carpet in the final world.

Various Graphics Issues
In Sand Oasis Zone shadows are totally dark and fire points have transparency problems. In some areas (non-sunny areas) the shadows are completely dark as well on console and this is not a glitch in Dolphin. The fire transparency issues don't seem to be around in latest master either.
