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.
