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.

Problems

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.

Shader Generation Stuttering and the Black Bar

This game suffers from severe stuttering during shader generation. Because of the differences between how the Wii works compared to personal computers, whenever something uses the Wii's GPU, Dolphin must generate a shader to emulate it on a PC GPU. Shader generation causes a slight emulation delay while it's being created, so Dolphin caches these shaders in its shadercache folder to help keep things smooth. Most games don't care about this and play fine, but with all of the games in Metroid Prime Trilogy, the shaders are so massive that they cause a significant delay, which creates a hard stutter and desyncs the GPU and CPU threads. 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. Going into new areas or showing new effects will cause the stutter and black bar, 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 stutter and desync if a new effect or region is loaded.

There is no solution at this time. Playing with Dual Core disabled or using Sync GPU Thread is the only solution currently available, and both result in a significant performance hit on one of Dolphin's most demanding games. See issue 5185.

  • PAL users can disable "PAL60 Mode (EuRGB60)" in the Wii settings to prevent the black bar from appearing. The stuttering during shader generation will remain, however.

Constant Wii Remote Disconnects

Since 3.5-471, when using the MS Bluetooth Stack (the default Bluetooth stack on Windows) this game will think that the wiimote is constantly disconnecting. Pressing Alt-F5 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.

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 issue 5573.

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 Copies to Texture Only is disabled. Though EFB Copies to Texture Only is forced off by the GameINI, visor corruption may still occur if you open the graphics configuration window during gameplay. Disable EFB Copies to Texture Only in the Dolphin GUI to avoid any problems. Additionally, the graphics hack "Disable Destination Alpha" needs to be off for the Scan Visor to work.

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. D3D is not affected by this problem in this game. Fixed by 4.0-5124.

Configuration

Only configuration options for the best compatibility where they deviate from defaults are listed.

Testing

This title has been tested on the environments listed below:

Test Entries
Revision OS CPU GPU Result Tester
r7689 Windows 7 x64 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
3.0-766 Windows 7 x64 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
4.0-2826 Windows 7 x64 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
4.0-4843 Windows 7 x64 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
4.0-5384 Windows Server 2012 x64 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
