To my knowledge, all of the GameCube versions of *Metroid Prime* and *Metroid Prime 2: [Dark] Echoes* only support 4:3, not 16:9 .
Currently, Dolphin's widescreen heuristic will fail to detect this and will erratically switch between 4:3 and 16:9 when Aspect Ratio is set to Auto.
These changes prevent the erratic aspect ratio switching by manually declaring that the game is solely 4:3.
The primary focus of this PR is the Eternal Darkness patch which fixes hanging at startup, which prior to this fix makes Eternal Darkness unplayable in hardcore. The MHTri patch was added as well simply because it could be.
The game calls GXSetDrawDone and then switches the GP fifo without first
waiting for the draw done interrupt to arrive. Before
e96960e2a6, Dolphin would not execute the
draw done command and potentially also skip other commands in the old GP
fifo. Since that commit, Dolphin executes the remaining commands on the
old GP fifo just before disabling reads for switching, but because
PixelEngineManager::RaiseEvent() enforces a minimum delay of 500 cycles
for the draw done interrupt, it arrives after the game has switched to
the new GP fifo which seems to trigger the deadlock.
This patch replaces the call to GXSetDrawDone by a call to GXDrawDone
which does the same but also waits for the interrupt.
Removes the EFBAccessEnable=false explicit game overrides for:
GT6 (Terminator 3: The Redemption)
GXB (SSX3) [deleted - no other configuration]
RTH (Tony Hawk's Downhill Jam)
SNC (SONIC COLOURS) [deleted - no other configuration]
Adjusts the Texture Cache settings/slider to 512 samples which equates
to the 'middle' option in the UI.
If using the 'Safe' Texture Cache Accuracy mode, the left screen will only render bloom in 2P modes.
If using the 'Fast' Texture Cache Accuracy mode, the Intro Movie will
drop frames near the end when the "Shadow the Hedgehog" game title
letters appear. This mode also can result in artifacts/bleed from bloom
effects in some situations.
`EFBEmulateFormatChanges = True` properly emulates the blur in the pause screen.
`ImmediateXFBEnable = False` to prevent epilepsy-inducing FMVs and main menu.

The use of any anti-aliasing will cause graphical corruption, which occurs on the ground.
MaxAnisotropy is supposed to be for [Video_Enhancements], but also it doesn't cause any of the issues in game so it is being removed rather than set under the correct heading.
Added a comment on why these values are set.
These codes are actually Gecko codes so setting that correctly.
There were errors which pop up when running this game as the comments for AR codes need to be set with hash(#) instead of asterisk(*). I replaced those anyways.
Removed the url in the comment since it's inaccessible and not on wayback machine either.
Also corrected the GameID, the wrong one is listed.
The wrong filename was used so the settings weren't being applied.
The graphical issues reported were from enhancements that create graphical issues.
EFBToTextureEnable solves some graphical issues but those issues appear for only a few frames, the bulk of the game does not benefit while the setting while it is very sore on performance.
Arbitrary Mipmap Detection doesn't work when GPU Texture Decoding is
enabled, so disable GPU Texture Decoding for games where the .ini
enables Arbitrary Mipmap Detection.

These patches were added in bde9a459cd
and enabled by default in 36ecfdd6b5.
They allowed the game to run in Dolphin but disabled dynamic shadows.
The game adds 4 to the start address of otherwise valid display lists
for no obvious reason. Now that Dolphin forces 32-byte alignment these
patches are no longer needed.
Prototype of a system to whitelist known game patches that are allowed to be used while RetroAchievements Hardcore mode is active. ApprovedInis.txt contains known hashes for the ini files as they appear in the repo, and can be compared to the local versions of these files to ensure they have not been edited locally by the player. ApprovedInis.txt is hashed and verified similarly first, with its hash residing as a const string within AchievementManager.h, ensuring ApprovedInis and the hashes within cannot be modified without editing Dolphin's source code and recompiling completely.
Adjusts widescreen heuristic values to work properly for both the original game and the widescreen hack versions of Shadow the Hedgehog (all regions), Game ID GUP.

This was causing the game to output thousands of FPS during the loading screen when it would run uncapped if Immediately Present XFB was enabled.
Please see Redmine 13447 for reference.
This is another one of those games that has an optional screenshot
feature where the images end up all black if you have Store EFB Copies
to Texture Only turned on. Like for other such games, let's not force
Store EFB Copies to Texture Only off, since it's a large performance
impact for a feature most players won't use.
There's one wrinkle here. As part of teaching the player how to take
screenshots, the game forces the player to take a screenshot before it
lets them progress in the story. However, the game doesn't care what's
in the screenshot, so you can progress just fine even if Store EFB
Copies to Texture Only is turned on. I personally tested it.
For buttons and some character icons the game loads palleted PNGs and
tiles the pallet indices directly into C4 textures but fails to take
into account that PNG and C4 use opposite nibble orders. This causes
adjacent pixel columns to be swapped, see issue 13370.
Also disable Immediate XFB for the Japanese release. It has the same
black screen and flickering issues as the other regions.
These games seem to constantly have unused vertices, and this is worst shown in the Shadow Pokemon purification cutscene. The Shadow Pokemon purification cutscene is even worse on XD with forced single core mode, as instead of having FPS dropping with VPS staying 60ish, it will drop both, resulting in audio stuttering. Turning on CPUCall seems to have a 7/8 reduction of draw calls for that cutscene (~800 -> ~100), doubling performance. Many other areas of the game seem to benefit from this setting too, having some kind of performance boost.
See https://bugs.dolphin-emu.org/issues/13248. This is needed for the menus to work properly (not run at 1FPS and render incorrectly). Additionally, immediate XFB causes flickering.
Cubivore had an old issue before Hybrid XFB was merged involving the screen shifting left. Immediate XFB actually brings the issue back. It should be disabled for this title.
These games greatly benefit from CPU Culling, and there isn't much reason
not to just blanket enable it for all users. There is no case where you'd
want it disabled.
A call to GXCopyDisp(), made once before the title screen for no
apparent purpose, is causing heap corruption, but it isn't observed on
real hardware thanks to the data cache. Skipping the call works too,
preventing a crash on the main menu.
