GameFileCacheService.startRescan (in MainPresenter.onResume)
does nothing if called before GameFileCacheService.startLoad.
Fixes a 3f71c36 regression where already added games would not
show up after app launch under specific circumstances.
Unfortunately the loading indicator still doesn't show up
during a rescan initiated by app launch, but that would
be more annoying to fix, so I will leave it for now.
When a save state is loaded, the IOS device serving bluetooth
is cast as BluetoothEmuDevice. If, however, a real Wiimote
with BT passthrough is used, this caused the game to crash.
Now the proper device class is used.
At a first glance it may look like a part of the code I added to
srawx in efeda3b has a bug when a == s. The code actually happens
to work correctly, but in the interest of making the code easier
to reason about, I'd like to change the way it's implemented. This
change should improve the pipelining a little in the a == s case too.
Fix Gamelist context menu item 'Open Containing Folder' opening wrong
target on Windows when game parent folder is [foobar] and grandparent
folder contains file [foobar].bat or [foobar].exe
Add trailing directory separator to parent folder path to force Windows
to interpret path as directory.

21c152f added a small hack to DVDInterface to keep WBFS and CISO
files working with Nintendo's "Error #001" anti-piracy check.
Unfortunately I don't think it's possible to support WBFS and
CISO without any kind of hack or heuristic, but what we can do
is replace the 21c152f hack (which applies regardless of file
format) with a hack that only is active when using WBFS or CISO.
This change is similar to 2a5a399, but the disc size is
calculated in a different way.
Add ! before unused variables to 'use' them.
Ubuntu-x64 emits warnings for unused variables because gcc decides
it should ignore the void cast around them. See thread for discussion:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66425
Loop index int i was being compared against GetControllerCount() which
returned a size_t. This was the only place GetControllerCount() was
called from so the change of return type doesn't disturb anything else.
Changing the loop index to size_t wouldn't work as well since it's
passed into GetController(), which takes an int and is called from many
places, so it would need a cast anyway on an already busy line.
...and let's optimize a divisor of 2 ever so slightly for good measure.
I wouldn't have bothered, but most GameCube games seem to hit this on
launch.
- Division by 2
Before:
41 BE 02 00 00 00 mov r14d,2
41 8B C2 mov eax,r10d
45 85 F6 test r14d,r14d
74 0D je overflow
3D 00 00 00 80 cmp eax,80000000h
75 0E jne normal_path
41 83 FE FF cmp r14d,0FFFFFFFFh
75 08 jne normal_path
overflow:
C1 F8 1F sar eax,1Fh
44 8B F0 mov r14d,eax
EB 07 jmp done
normal_path:
99 cdq
41 F7 FE idiv eax,r14d
44 8B F0 mov r14d,eax
done:
After:
45 8B F2 mov r14d,r10d
41 C1 EE 1F shr r14d,1Fh
45 03 F2 add r14d,r10d
41 D1 FE sar r14d,1
Add a function to calculate the magic constants required to optimize
signed 32-bit division.
Since this optimization is not exclusive to any particular architecture,
JitCommon seemed like a good place to put this.
Zero divided by any number is still zero. For whatever reason, this case
shows up frequently too.
Before:
B8 00 00 00 00 mov eax,0
85 F6 test esi,esi
74 0C je overflow
3D 00 00 00 80 cmp eax,80000000h

Nothing!
When the dividend is known at compile time, we can eliminate some of the
branching and precompute the result for the overflow case.

Fairly common with constant dividend of zero. Non-zero values occur
frequently in Ocarina of Time Master Quest.
Whether the custom RTC setting is enabled shouldn't in itself
affect determinism (as long as the actual RTC value is properly
synced). Alters the logic added in 4b2906c.
I'm not entirely certain that this is correct, but the current
code doesn't really make sense to me... If we need to force the
RTC bias to 0 when custom RTC is enabled, why don't we need to
do it when custom RTC is disabled? The code for getting the
host system's current time doesn't contain any special handling
for the guest's RTC bias as far as I can tell.
The loop in WIARVZFileReader::Chunk::Read could terminate
prematurely if the size argument was smaller than the size
of an exception list which had only been partially loaded.
BPMEM_TEV_COLOR_ENV + 6 (0xC6) was missing due to a typo. BPMEM_BP_MASK (0xFE) does not lend itself well to documentation with the current FIFO analyzer implementation (since it requires remembering the values in BP memory) but still shouldn't be treated as unknown. BPMEM_TX_SETMODE0_4 and BPMEM_TX_SETMODE1_4 (0xA4-0xAB) were missing entirely.
Additional changes:
- For TevStageCombiner's ColorCombiner and AlphaCombiner, op/comparison and scale/compare_mode have been split as there are different meanings and enums if bias is set to compare. (Shift has also been renamed to scale)
- In TexMode0, min_filter has been split into min_mip and min_filter.
- In TexImage1, image_type is now cache_manually_managed.
- The unused bit in GenMode is now exposed.
- LPSize's lineaspect is now named adjust_for_aspect_ratio.
Additionally, VCacheEnhance has been added to UVAT_group1. According to YAGCD, this field is always 1.
TVtxDesc also now has separate low and high fields whose hex values correspond with the proper registers, instead of having one 33-bit value. This change was made in a way that should be backwards-compatible.
We want to save the currently selected platform tab,
but doing so immediately after switching tabs leads to
unnecessarily much file I/O (on the main thread, no less).
This change makes us defer the saving until later.
In master, the game scanning process looks like this:
1. Scan for games
2. Scan for additional metadata (icon.png and meta.xml)
3. Save the cache if needed
4. Update the game list with the results
This change makes the game scanning process look like this:
1. Scan for games
2. Update the game list with the results
3. Scan for additional metadata (icon.png and meta.xml)
4. Update the game list with the results
5. Save the cache if needed
Updating the game list as soon as possible means the user
has to wait less before their games show up. The new behavior
matches what DolphinWX did before it was removed. (DolphinQt
has an even fancier approach where games get added one by one.)
The PPC is supposed to be held in reset when another version of IOS is
in the process of being launched for a PPC title launch.
Probably doesn't matter in practice, though the inaccuracy was
definitely observable from the PPC.
