Changes many patch_manager functions to use a case-less variant of
GetSubdirectory. Fixes patches not showing up on *nix systems when
patch directories are named with odd cases, i.e. `exeFS'.
Previously, we were reading the keys everytime a KeyManager object was created, causing yuzu to reread the keys file multiple hundreds of times when loading the game list.
With this change, it is only loaded once.
On my system, this decreased game list loading times by a factor of 20.
Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.
We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).
While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.
After further hardware investigation, it appears that some games, perhaps those more lazily coded, will not call EnsureSaveData, meaning that they expect the normal (current) save to be automatically made. Additionally, some games do not create a cache or temporary save before use.
In these 3 specific instances, the save is created automatically for the game if it doesn't exist.
This only encourages the use of the global system instance (which will
be phased out long-term). Instead, we use the direct system function
call directly to remove the appealing but discouraged short-hand.
Migrates the HLE service code off the use of directly accessing the
global system instance where trivially able to do so.
This removes all usages of Core::CurrentProcess from the service code,
only 8 occurrences of this function exist elsewhere. There's still quite
a bit of "System::GetInstance()" being used, however this was able to
replace a few instances.
This is to go with the Atmosphere VM port, now it just contains the callbacks needed for the interface between DmntCheatVm and yuzu, along with the cheat parsers.
