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 it's 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 adds 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 exists for the Wii as part of the Metroid Prime: Trilogy.

Micro-stuttering
All of the Prime games suffer from micro-stuttering: screen redraws and small stops in the video that can become very annoying. It occurs on both DSP HLE and DSP LLE, but DSP LLE appears to make it worse. It's severity varies depending on the revision used. Micro-stuttering can trigger the Black Bar glitch.

Audio Issues
With DSP HLE several sounds don´t play appropriately, and sometimes music stops playing. DSP LLE greatly improves on these problems, but some issues can still remain. See.

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.

Visors
Scanner/Visors will only work if EFB to Ram is enabled. However, EFB to Ram is set as default within the game INI, preventing the user from using anything but EFB to Ram for this game.

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.
