Some games are showing frame flickering, e.g. Pokémon games when only
the text at the bottom of the screen is updating. GB/GBC games are
apparently especially affected, presumably due to the extra border.
These two games have some strange rendering behaviors and therefore can't use the generic bloom actions.
These games have several bloom EFB copies and they draw that on top of an already rendered game. After doing that, they render some other draw calls to "fixup" the bloom that it drew to effectively remove it. This isn't uncommon but there is one special thing these games do...they use a RAM EFB copy for the 'fixup'. This means when playing with high IR, the game will look blurry in specific parts of the screen where the game was attempting to fix the copy!
Bloom removal has addressed this by removing all the draw calls related to the bloom, including the fixup draws. The user then needs to turn on 'EFB Copy To Texture Only' for the best visuals (De Blob 2 in particular is broken without this) as the default settings.
Bloom blurred will need special attention too but Dolphin doesn't currently have enough functionality to handle it.
Add a mod for all games with bloom targets that blurs the bloom based on resolution using a custom material. The shader exposes bloom brightness and the amount of spread through uniforms (not exposed in the UI yet).
The original shader logic was done by TryTwo. This shader was reworked for graphics mods and cleaned up slightly.

This is fixed by setting Texture Cache Accuracy to Safe.
Affected titles:
- R2F Freddi Fish: Kelp Seed Mystery
- RDL Spy Fox in Dry Cereal
- RJQ Pajama Sam: Don't Fear the Dark
TimeSplitters: Future Perfect is crashing if page table fastmem is
enabled. The reason hasn't been analyzed yet. For the time being, let's
use GameSettings to bring back the old behavior of not having page table
fastmem.
Fixes https://bugs.dolphin-emu.org/issues/14000.
Set suggested aspect ratio to 4:3 due to dolphin incorrectly setting it to 16:9 automatically.

I've gone through all relevant settings for Rogue Squadron II and III
and overhauled their game INI files. Each setting is explained with a
comment.
Some settings I chose not to include:
* EFB to RAM only seems to affect certain fadeouts in Rogue Squadron II.
Without it, the affected fadeouts are replaced by a pure black screen.
I don't think this is important enough to warrant the performance hit.
* As I was unable to find anything Rogue Squadron III needs EFB to RAM
for, I also didn't find anything it needs DeferEFBCopies disabled for.
* I didn't find anything EFBEmulateFormatChanges was needed for in
either game.
* Enabling EFB access makes the ship engine glow visible in Rogue
Squadron III, but this effect is minor enough that you probably won't
notice it's missing unless you know it's supposed to be there. Since
this is Dolphin's heaviest game, let's give users the choice.
* I was considering forcing XFB to RAM for Rogue Squadron III to make
fadeouts render properly instead of going from magenta to black, since
enabling XFB to RAM doesn't really hurt performance when you're
already enabling EFB to RAM. But then I was unable to find a reason
why we should enable EFB to RAM for this game.
Tested in RS2 and RS3. The RS3 demo disc settings are copied from the
RS3 settings and haven't been tested by me.
