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.

Problems

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.

Micro-stuttering

All of the Prime games suffer from micro-stuttering: screen redraws and 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. Micro-stuttering can trigger the Black Bar glitch.

Audio Problems, Stalls

The game will have numerous audio problems with DSP HLE, such as sound effects issues and a few seconds of music randomly looping forever. And it may stall out during the "Input Identity Code" sequence at the start of the game. Use DSP LLE to insure proper audio. See issue 5563.

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 D3D11 graphics backend.

Black Bar

Whenever Dolphin has trouble with the game and flickers, from a loading hiccup to taking a screenshot, a black bar will appear on the bottom of the screen, taking up 15% of the screen space and "squishing" the game in the remaining space. This occurs in all graphics backends, and there is no known solution, but OpenGL is the most resistant. See issue 5185. Old versions of Dolphin, such as 3.0-135, do not have this issue on all backends.

Correct emulation

Black bar and squishing

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 from the low resolution bloom. See issue 5573.

OpenGL Slowdown

OpenGL has problems with slowdown while showing refraction effects, such as raindrops on Samus' visor and the heat effect after firing her weapon for an extended period. On Metroid Prime 3 alone, it also has slowdowns when several grapple points (yellow pulsing) are present on screen at once. Even the strongest computers will slow to a crawl from this, and there is no solution in the OpenGL backend. D3D9 and D3D11 are not affected by this issue.

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.

Visors

Visors will only work if EFB to Ram is enabled. However, EFB to Ram is set as default within the game INI, preventing the user from using anything but EFB to Ram for this game.

Slow Speed

Starting with 3.5-367, the game is unable to run at full speed on any computer. The emulator will show 60vps and 100% speed, but the fps and the actual speed of the game will be 10-20fps. Adjusting the Framelimiter cannot correct it, and Accurate Vbeam Emulation makes it even worse. Holding Tab or turning off the Framelimiter eliminates the slowdown, but makes the game run too quickly. See issue 5982. Fixed by 3.5-380.

Wiimote Lag

The game may experience a large amount of Wii Remote lag. Insure "Alternate Wiimote Timings" is active in the game settings to correct it. Dolphin 3.0 does not have this setting, making controlling this game very difficult for that version. Fixed and the option removed by 3.5-354.
