Metroid Prime 3: Corruption (Wii)

Metroid Prime 3: Corruption is a first-person action-adventure game developed by Retro Studios and published by Nintendo for the Wii video game console. It is the tenth game in the Metroid series, and the final entry in the Metroid Prime Trilogy. The Wii Remote and Nunchuk devices are featured in a new control scheme that took a year to develop and caused the game's release to be delayed several times.

Gameplay for Metroid Prime 3 is similar to its predecessors: players explore open ended worlds, finding story clues and power ups, solving puzzles, jumping on platforms, and fighting enemies. Unlike past games however, the game is divided into several open worlds; each world is smaller than the single open world environments of Metroid Prime or Metroid Prime 2, but the combined size is greater. As with Metroid Prime 2, exploring the worlds is not aimless: players explore the world freely, but there are specific tasks meant to be accomplished on each world which are told to you beforehand. The game also includes hypermode, a phazon overload system that allows players to exchange health for massive damage. The biggest change is the controls. Metroid Prime 3 uses a new control system using the Wii Remote and Nunchuk, allowing free aiming and movement similar to mouse and keyboard controls.

Metroid Prime 3 was also included in Metroid Prime: Trilogy, which includes updated versions of its prequels: Metroid Prime and Metroid Prime 2: Echoes.

Random Crashes
Prime 3 has a tendency to crash randomly, its severity depending on the revision used. There is no known solution to this problem at this time, but restarting should allow you to get past the crash point. Save often.

Savestates
Using savestates in MP3 will crash Dolphin. Use the in-game saving to avoid any problems.

Constant Wiimote Disconnects
Since, Prime 3 will think that the wiimote is constantly disconnecting. Pressing Alt-F5 will restore it, but it will disconnect again seconds later. Disable "Enable Speaker Data" to solve this problem.

Black Bar and Severe Stutters
At seemingly random points throughout the game, the game will freeze for an instant, flashing to black and "redrawing". When it comes back, a black bar will be at the bottom of the screen, taking up 15% of the screen space and "squishing" the game in the remaining space. From thorough testing, this apparently occurs whenever the emulator stops the GPU thread for a split-second, causing the GPU and CPU threads to desync. Most games don't care about this, but Prime 3 freaks out and creates this error. Creating a new shadercache, from first run of the game or from going into a new area, will immediately cause the desync, as well as going in and out of fullscreen and even taking a screenshot. Building up a shadercache of an area helps, but it will still desync if a new effect or region is loaded. Playing with Dual Core disabled or using Sync GPU Thread is the only solution at this time. See.
 * PAL users can disable "EuRGB60 Mode (PAL60)" in the Wii settings to prevent this issue.

Micro-stuttering
All of the Prime games suffer from micro-stuttering: small stops in the video that can become very annoying. It occurs in all graphics backends, but the OpenGL backend has consistently been the most resistant to the problem. DSP HLE and DSP LLE are both affected, though DSP LLE appears to make it worse in some revisions. Its severity varies depending on the revision and settings used, so if you want to play the game you should try a wide variety of combinations.

Pixelation Glitches
A large pixelated block may appear in the upper left area of the frame. It may only appear during movement (newer revisions) or be stuck there permanently (older revisions). To avoid this problem, use the D3D graphics backend.

Refraction Slowdown
Refraction effects, such as raindrops on Samus' visor and the heat effect after firing her weapon for an extended period, cause slowdown on all backends. OpenGL is affected worse, though D3D is affected as well. It also has slowdowns when several grapple points (yellow pulsing) are present on screen at once. Even the strongest computers are affected by this issue, and there is no solution at this time.

Bloom Offset
Prime 3 has noticeable bloom offset problems. It will have several copies of the bloom spread out from the source, and can be very distracting. The only solution is to disable "Scaled EFB Copy", but this has some issues of its own. See.

Visors
Visors will only work if EFB to Ram is enabled. Though EFB to Ram is forced by the GameINI, visor corruption may still occur. Turn on EFB to Ram in the Dolphin GUI to avoid any problems.

Dot
When playing above 1x Native internal resolution, there is a dot in the center of the screen. It's small and easy to ignore, but it's always there. There is no fix for this problem.
