Metroid Prime 2: Echoes (GC)

Metroid Prime 2: Echoes, known as Metroid Prime 2: Dark Echoes (メトロイドプライム2: ダークエコーズ Metoroido Puraimu Tsū: Dāku Ekōzu) in Japan, is a first-person, action-adventure video game developed by Retro Studios and published by Nintendo for the GameCube. It is the seventh published game in the Metroid series and a direct sequel to Metroid Prime.

Like its predecessor, Metroid Prime 2: Echoes takes place in an open-ended world with interconnected regions, revolving around solving puzzles to uncover secrets, platform jumping, and shooting enemies. Echoes features parallel dimensions gameplay, Light Aether and Dark Aether, where changes in either dimension often reflect changes in the other. Dark Aether's atmosphere is caustic and damages Samus' Power Suit, requiring the player to move between designated "safe zones" that allow Samus' health to be regained slowly.

An updated version was released for the Wii as part of the Metroid Prime Trilogy.

Shader Generation Stuttering and the Black Bar
This game suffers from severe stuttering during shader generation. Because of the differences between how the Gamecube works compared to personal computers, whenever something uses the Gamecube'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 this game, 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 are the only solutions currently available, and both result in a significant performance hit. See and.

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 is present whenever the HUD is on screen. There is no fix for this problem.

Broken Scan Visor
If 'Skip Destination Alpha Pass' is turned on, the scan visor will display nonsensical data and fail to work. Running the game without this option fixes the problem.

Refraction Slowdown
Refraction effects, such as raindrops on Samus' visor, 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.
