Metroid Prime 2: Echoes (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 2 in Trilogy has been updated with many features from Metroid Prime 3, such as its aiming system, bloom rendering, 16:9 aspect ratio, and reduced difficulty level (to play the original difficulty, play "veteran" instead of normal). The update also has higher resolution textures, and uses Trilogy's menus, save system, achievements, and unlockable soundtracks.

Game Pages
This page should be used for specific issues with the Metroid Prime 2: Echoes sub-game of Metroid Prime: Trilogy. For other Metroid Prime: Trilogy games or launcher information, please see the following pages.



Performance
Performance in general seems reduced compared to the game's GameCube counterpart. This may be related to the higher resolution textures and various new screen effects added for the Trilogy versions.

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 2 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.

Constant Wiimote Disconnects
Since, the game 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.

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. 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.

Bloom Offset
Like Prime 3 and all the Trilogy games, Prime 2 Trilogy has bloom offset problems. Fortunately, it is not very noticeable with this game. There is no known solution to this issue. See.

Refraction Slowdown
Refraction effects, such as raindrops on Samus' visor and the heat effect after firing her weapon for an extended period, cause slowdown in OpenGL. Even the strongest computers are affected by this issue, and there is no solution with the OpenGL backend at this time. D3D11 and D3D9 are not affected by this problem in this game.

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. 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. Additionally, the graphics hack "Skip Dest. Alpha Pass" needs to be OFF for the Scan Visor to work.

Excessive Reverb
Since the new-ax-hle 2.0 merger in, all sound effects in Metroid Prime 2 have excessive reverberation when using DSP HLE. The only solution at this time is to use DSP LLE. See. Fixed by an unknown revision between and.

Distorted Audio with DSP HLE
The New-AX-HLE 2.0 merger in causes SEVERE audio problems with DSP HLE with DSP on Dedicated Thread disabled. Run DSP HLE with DSP on Dedicated Thread on, or use DSP LLE. See. Fixed by.

Wiimote Lag
The game may experience a small amount of Wii Remote lag. Use "Alternate Wiimote Timings" in the game settings to correct it. Fixed and the option removed by.
