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.

Shader Compilation Stuttering
Metroid Prime 2: Echoes (Metroid Prime: Trilogy) is one of the most susceptible titles to shader compilation stuttering. The GC and Wii have no concept of shaders - everything is executed directly by the hardware without an intermediate programming language (API). Modern computers and mobile 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 directly. Shaders have to be generated though, 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 a few demanding titles, the shaders that they generate are so large that they can result in noticeable stuttering, in severe cases pauses of over a second may occur.
Changing GPU, updating GPU drivers, or updating Dolphin may invalidate the shader cache, requiring specialized shaders to be compiled again. Since , Dolphin caches shader pipeline UIDs independently of the video backend and compiles them on game start. This allows cached shaders to work across different video backends, platforms, hardware configurations and even Dolphin versions as long as changes aren't made to Dolphin's actual shader pipeline. These shaders are compiled in the background when the game starts, which may cause stuttering for a short period. Enable Compile Shaders Before Starting to avoid this.
Constant Wii Remote Disconnects
Dot in IR>1
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. It can be hidden along with the helmet and visor display in the game's options.
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.
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 September Progress Report., 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
Only configuration options for the best compatibility where they deviate from defaults are listed.

The graph below charts the compatibility with Metroid Prime 2: Echoes since Dolphin'srelease, listing revisions only where a compatibility change occurred.
This title has been tested on the environments listed below:
|Windows 7||Intel Core i5-2500K @ 4.4GHz||NVIDIA GeForce GTS 250||Close to perfect -> constant 60FPS, 1280x720, 3xNative textures and DSP-HLE sound (still must use dol swap though)||Zlutz|
|Windows 7||Intel Core i7-3770K @ 4.4GHz||AMD Radeon HD 6970||DX11 at 1900x1200 (using internal resolution auto, 4xAA), averages 50FPS. EFB-copy-to-RAM must be used 100% of the time for the scan visor to function (contrast to MP1 where it is only required for the rarely-used x-ray visor), but fastest cache option can be used (causes very minor graphical glitches). "Skip Destination Alpha Pass" also breaks the scan visor and should be left off. "Accurate V-Beam" (in right-click options) provides noticeable speedup in large rooms with no ill effect. DSP-HLE works fine, except for very occasional loss of BGM (can be resolved by save/load or reset); DSP-LLE does not drop BGM but instead causes crackling and clicking sounds whenever framerate drops below 60FPS. OpenMP texture decoder, cache display lists, and disable fog/per-pixel-depth are all recommended for slight speedup. DOL swap still required to run.||anon|
|Windows 7||Intel Core i7-4790K @ 4.6GHz||AMD Radeon HD 7970||OpenGL at 1920x1080 (3x internal res), no AA, 4x AF, works consistently at 58-60FPS so far - I will update if I see similar drops like I saw in MP1||anon|
|Windows 7||Intel Core i5-750 @ 2.66GHz||NVIDIA GeForce GTX 680||ES_Launch problems now solved, no problems with speaker data. Direct 3D, EFB to RAM used. Frequent drops to 25FPS and I must go to windowed then fullscreen again to gain 50FPS. Everything OK otherwise.||Paulli|
|Windows Server 2012||AMD FX-8350 @ 4.6GHz||AMD Radeon HD 7970||D3D @1920x1080 (3x IR), no AA, 1x AF, playing at PAL50. Runs very nicely, minor FPS drops when entering water and in some places, otherwise constant 50FPS. Played all the way through without major glitches.||XorUnison|
|SteamOS 2.60||Intel Core i3-4170 @ 3.7GHz||NVIDIA GeForce GTX 750 Ti||OGL, 3x IR, no other enhancements, NTSC-U. Fullspeed aside from portal transitions (where crackling audio is the only noticeable effect). No glitches as far as I could tell.||monojin|
