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.

Emulation Information

Shader Compilation Stuttering

Metroid Prime 3: Corruption (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. Specialized 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.

Since 5.0-4869, this problem can be solved by enabling ubershaders. Additionally, since 5.0-6461, cached 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.

Problems

Solid Color Background in Pause Menu

If the game is paused while the Scan Visor is active, the background in the pause menu will be a solid color instead of a blurred screenshot of the gameplay.

Currently, the only workaround is the check Disable Fog in the Graphics settings. Refer to issue 13711.

Enhancements

Bloom Offset in IR>1

Metroid Prime 3 has been prominent in using blooming effects unlike the other Metroid Prime: Trilogy games, and therefore the blooming offset problem in this game became more noticeable than others. It will have several copies of the bloom spread out from the source, and can be very distracting. Disabling Scaled EFB Copy in Dolphin's settings will influence how the blooming effects should look, but this has some issues on its own, such as upper-left part of the screen become pixelated. It's a problem belonging to resolutions that the real Wii never had.

Example of the bloom offset

Another example of the offset

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.

Another workaround for this problem is to put these custom textures into the Dolphin Emulator\Load\Textures folder and enabling the Load Custom Textures option in the advanced graphics settings.

Testing

This title has been tested on the environments listed below:

Test Entries
Revision	OS	CPU	GPU	Result	Tester
3.0-735	Windows 7	Intel Core i5-3570K @ 4.7 GHz	NVIDIA GeForce GTX 275	Used Dol swapping. MP3 with LLE and EFB to RAM are difficult even for my system; it usually is at 60FPS but drops are common. I experienced all the problems listed above.	MayImilae
3.5-392	Windows 7	Intel Core i7-2600K	NVIDIA GeForce GTX 560	"Accurate VBeam emulation" enabled in properties file. Direct3D11 backend, EFB to texture, 2.5x resolution, DSP HLE and XAudio2. Tested in first Norion section - almost perfect emulation, slight slowdown when using Scan Visor, and the odd tiny audio blip. Dot glitch present. (PAL version.)	-
5.0-10155	Windows 10	Intel Core i7-7800X @ 4 GHz	NVIDIA GeForce GTX 960	Virtually perfect on Vulkan with Ubershaders, other than the problems already listed. Default settings with the latest dev versions, loading custom textures, 3x native res, and only the occasional stutter (often only related to other processes on my system), even when loading rooms. Enabled WiiMote speaker data and didn't get disconnects with DolphinBar, but didn't seem to get any sound out of it anyway.	Malkierian
