Sonic Unleashed (released as Sonic World Adventure in Japan), is a video game in the Sonic the Hedgehog series developed by Sonic Team and published by Sega for multiple platforms in 2008. The game follows Sonic the Hedgehog as he attempts to restore the world to normal after his nemesis, Doctor Eggman, splits the world into pieces, as well as his struggles with his new beast form, Sonic the Werehog. Gameplay features two distinct styles, with each being played either during daytime or night-time. Daytime stages incorporate Sonic's traditional platforming and trademark speed, with a combination of behind-the-back third-person viewpoints and 2D side-scroller platforming; gameplay seamlessly transitions between these two views. Night-time levels see Sonic transform into the Werehog; gameplay slows down to accommodate greater platform play, and involves combat against waves of enemies using the Werehog's brute strength.


Audio Crackling

Sound sometimes experiences strange crackling, at least on the Mac builds of Dolphin.


Dolphin occasionally crashes when running this game.

Sonic Unleashed has very unusual depth clipping issues, resulting in a black screen if the game is not perfectly emulated. For years, these problems were fixed by the "Sonic Unleashed hack", a very messy and annoying projection hack. In 4.0-564, this hack was removed so a proper fix could be found. This broke OpenGL compatibility, but D3D continued to render since depth clipping was broken in that backend. However, this clipping bug was fixed in 4.0-3748, leaving this game broken in both backends. Fixed by a proper implementation in 4.0-4451. See issue 6914 and the Dec 2014 Dolphin Progress Report for details.


This title does not need non-default settings to run properly.

3.0-415 Mac OS X 10.6.8 Intel Core 2 Duo @ 2.13GHz NVIDIA GeForce 9400M Playable, but in day stages, sound stutters. Avg. emulation speed is about 60%. When using a real Wii Remote, boosting is difficult on the ground; it has to be shaken at just the right speed or it won't happen. It's easier to just use a Classic Controller instead. Ac
3.0-458 Mac OS X 10.7.4 Intel Core i7 @ 2.6GHz NVIDIA GeForce GT 650M Nearly perfect with default settings! There are bits of stutter here and there, but speed has never dropped below 80% as of now. Much better than my previous attempt above, though sound still stutters at random intervals (accompanied by slowdown). Ac
3.0-594 Windows 7 Intel Core i7-2630 @ 2GHz NVIDIA GeForce GTX 460M Playable speed, usually around 60-80%, daytime stages result in noticeable sound errors. DiscoBiscuit
