Metroid Prime 3: Corruption (Metroid Prime: Trilogy)

Metroid Prime: Trilogy is an action-adventure video game compilation developed by Retro Studios and published by Nintendo for the Wii video game console. It features Metroid Prime, Metroid Prime 2: Echoes, and Metroid Prime 3: Corruption on a single dual-layer disc.

Metroid Prime 3 in Trilogy is more or less a direct copy of the original Wii release. However, it uses the Metroid Prime Trilogy menus, achievements, saving system, and unlockable soundtracks; and it has extended versions of the Bryyo music tracks to make them less repetitive.

Game Pages
This page should be used for specific issues with the Metroid Prime sub-game of Metroid Prime: Trilogy. For other Metroid Prime: Trilogy games or launcher information, please see the following pages.



Constant Wii Remote Disconnects
Since, when using the MS Bluetooth Stack (the default bluetooth stack on Windows) Prime 3 will think that the Wii Remote is constantly disconnecting. Pressing a button on the Wii Remote will restore it, but it will disconnect again seconds later. Windows users can disable "Enable Speaker Data" to solve this problem, or move to either the Toshiba Stack or the DolphinBar.

Shader Compilation Stuttering
The Metroid Prime games are some of the most susceptible titles to shader compilation stuttering, thanks to a combination of very complex effects and dynamic loading. The GC and Wii have no concept of shaders - everything runs directly "on the metal" without any APIs. Modern desktop and phone systems do not work in this way, requiring the use of shaders as an intermediary so your system's GPU can perform the tasks that the GC and Wii GPU performed. But shaders have to be created, and since GC/Wii games are not designed to create shaders ahead of time as a PC game would, when a new effect appears Dolphin has to delay the CPU thread while the GPU thread performs the compilation; a pause that does not exist on the consoles. For most games shader generation takes only a few milliseconds, but for the Metroid Prime series and a few other demanding titles, the shaders that they generate are so large that they can result in noticeable stuttering.

Eventually stuttering will reduce as a shader cache is built up, but there is no solution to this problem 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
The Scan visor will only work if Store EFB Copies to Texture Only is disabled. Though Store EFB Copies to Texture Only is forced off by the GameINI, visor issues may still occur if the graphics configuration window is opened during gameplay. Disable Store EFB Copies to Texture Only 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.

The Black Bar
During Shader Compilation, stuttering can become so severe that it desyncs the GPU and CPU threads in Dual Core mode. The game freaks out over this desync, creating a black bar at the bottom of the screen, which takes up 15% of the screen space and "squishes" the game in the remaining space. The black bar will remain there from then on whether stuttering continues or ceases.

After, enabling Virtual XFB or Real XFB will fix and/or prevent the problem. If XFB is disabled the problem may still occur. Details can be found in the September Progress Report.

Savestates
Using save states in MP3 will crash Dolphin. Use the in-game saving to avoid any problems. Seems to have been fixed in the recent builds ( and onward).

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. Fixed by, and detailed in the February Progress Report

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. Fixed by.
