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.

Audio Issues

Several sounds don´t play appropriately, and sometimes music stops playing. DSP LLE fixes the sound effect problems, but it does not fix all BGM issues. LLE also causes stuttering problems. See issue 5563.

Wiimote Lag

The game may experience a small amount of Wii Remote lag. Use "Alternate Wiimote Timings" in the game settings to correct it.

Visors

Visors will only work if EFB to Ram is enabled. Unlike the original Prime releases, Trilogy does not have EFB to Ram enabled by default in the GameINI, and must be set manually.

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. See issue 5574.

Correct emulation

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.

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 50 FPS. 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 60 FPS. 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
