Patching the game for not Windows

  • For Not Windows

    • Extract the game files (You can use NODTool, Dolphin, or any app that can extract the full game filesystem and rebuild it.)

    • Use a vcdiff xdelta3 patcher to patch GGuiSys.pak and Standard.ntwk in the game files with this mod's vdiff files:

      • vcdiff/GGuiSys.pak.vcdiff patches files/GGuiSys.pak
      • vcdiff/Standard.ntwk.vcdiff patches files/Standard.ntwk

    • Replace the original game's GGuiSys.pak and Standard.ntwk with the newly patched files

    • Rebuild the ISO (Or start the game directly from extracted files if using Dolphin (File -> Open, browse for sys/main.dol))

Widescreen for Dolphin: Widescreen Hack Method

[!WARNING] This method may be more prone to crashing.
The VR Culling code in this method may cause the game to render more objects than the game can handle.
It's only suggested to use this method if you want to play on a wider non-16:9 screen or window. Otherwise, it is recommended to use the Gecko Code Method instead.

In Dolphin,

  1. Choose Force 16:9 or Stretch for the Aspect Ratio
    (Options -> Graphics Settings -> General -> Aspect Ratio)
  2. Enable Widescreen Hack
    (Options -> Graphics Settings -> Enhancements -> Check Widescreen Hack)

To fix frustum culling problems (seeing stuff pop in and out near the left/right edges of the screen), use this Gecko code:

For Dolphin versions older than Dolphin 2503
To fix the game flickering between normal and stretched view, edit the game INI to add the following setting.
(To edit game INI settings, right click Metroid Prime 2: Echoes in the game list -> Properties -> Game Config tab -> Editor
There, you can add the setting to the User Config section)

[Video_Settings]
SuggestedAspectRatio = 2

This affects the official releases of Dolphin Emulator. This fix is not needed for Dolphin 2503 or later or PrimeHack.
