Internal details: The large region is split into individual same-sized blocks of memory. On creation, we allocate a single block of memory that will always remain zero, and map that into the entire memory region. Then, the first time any of these blocks is written to, we swap the mapped zero block out with a newly allocated block of memory. On clear, we swap back to the zero block and deallocate the data blocks. That way we only actually allocate one zero block as well as a handful of real data blocks where the JitCache actually writes to.
Emulation state changed signals also update the wiimote connection. The signal here is only needed for wiimote connects/disconnects.
Can fix erroneous debugger behavior during booting, as dolphin will sometimes incorrectly report the state as paused, which leads the debugger widgets to run when they shouldn't.
When an achievement is "primed", a challenge is active, for example completing a portion of the game in under a time limit or without taking damage or using certain items. This is stored in a map in the Achievement Manager (and removed when the achievement is unprimed) so a later commit can display it on screen.
The Disabled state sits between Game Closed and completely Shutdown - stronger than the former, as it refuses to let a game be opened again until AchievementManager is restored (which only happens upon a fresh core boot) but it isn't completely shut down and will still allow the player to be logged in and access the achievement settings and their (global) achievement header.
This change splits LoadGameAsync into three methods: two HashGame methods to accept either a string filepath or a volume, and a common LoadGameSync that both HashGames call to actually process the code. In the process, some minor cleanup, and the hash resolution now takes place on the work queue asynchronously.
Normally we only flush registers right at the end of each PPC
instruction. However, for PPC instructions that use a lot of registers
one at a time, it's beneficial to do this flushing work in the middle
of the instruction instead, reducing the risk of register starvation
and improving pipelining.
This should have been done when rebasing 6cc4f593e5 after the merge of
3a00ff625e. There are no correctness implications as far as I know,
only very minor performance implications.
Play Input Recording would potentially unlock achievements without any player input and needs to be disabled. If a recording is already playing, hardcore mode cannot be enabled.
The player getting a better view of their surroundings than the game would normally allow could possibly give the player an advantage over the original hardware, so Freelook is disabled in hardcore mode. To do this, I disable the config flag for Freelook when it is accessed, to make sure that it is disabled whether it was enabled before or after hardcore mode was enabled.
Memory patches would be an easy way to manipulate the memory needed to calculate achievement logic, so they must be disabled. Riivolution patches that do not affect memory are allowed, as they will be hashed with the game file.
