zcomploc is a feature of the GC/Wii GPU used to perform some depth operations.
It was previously not implemented in Dolphin. This commit adds support for it.
List of games fixed by this commit:
* 007: Everything or Nothing (Skybox in front of the map/models)
* Baten Kaitos (characters displayed in front of background objects)
* Tony Hawk's Pro Skater 3 (invisible skater)
* Ty the Tasmanian Tiger (floating floor)
* Super Smash Bros Brawl ("Link chasing pig" animation behind the score screen)
Fixes issue 4841.
/fp:fast was introducing FP precision problems, and mixing it with some
/fp:precise code caused strange game behaviors, DSI exceptions and freezes.
This commit should fix most of the issues introduced by 3.0-73 (r95517a97).
Thanks to [email protected] for tracking a lot of these Win32 bugs.
Fixes issue 4906.
Fixes issue 5138.
Probably fixes (not tested) issue 5067.
Use the clobber list instead of the stack to save rbx when executing the cpuid
instruction with inline assembly. This avoids breaking GCC assumptions about
the stack pointer location.
This is arguably better then using the slot0 device for slot1, because it maps
the real hardware better (nothing can be mounted on slot1 on a Wii AFAICT).
This also makes Kirby: Return to Dreamland work properly and fixes some of the
SD card problems (libs do not expect to have the same SD card mounted two times
in RW...).
This reverts commit 9a627e89fb.
The attempted Kirby: Return to Dreamland fix does not work properly and while
it fixes this particular game, it completely breaks SD card support on Dolphin.
BTW, I've never head of /dev/sdio/slot2 before...
To enforce SM2.0 compatibility, the OpenGL plugin was made to crash when
compiling a shader which does not fit in the SM2.0a limits. However, on some
combinations of OS/drivers/GPU, our shaders already do not fit in these limits,
causing artificial failures only to try to keep a non existant SM2.0a compat.
Basically, this sucks.
This commit increases the artificial limit to SM3.0. If you're using a GPU
which does not support SM3.0 and Dolphin works properly, this should not cause
any problem at all.
On Linux with recent versions of gettext these formatting fixes are done
automatically by gettext when updating the PO files. They create conflicts each
time a rebase / merge is done and need to be reset manually.
Most of the games using EFB peeks are suffering from major performance problems
when these peeks are not disabled in the graphics settings. This is an attempt
to fix this in the GL renderer by doing the glReadPixels in bulk: instead of
doing a lot of 1x1 pixel reads, read for 64x64 pixels at once and keep that in
a cache.
Deck menu in Baten Kaitos: 3FPS -> 54FPS
Character creation in Monster Hunter Tri: 7FPS -> 60FPS
zcomploc is a feature of the BP which switch depth test from before the alpha
test to after the alpha test. This way, transparent fragments are written to
the depth buffer too.
The current implementation is quite hacky and does not cover all cases but is
enough to fix problems in a lot of game. A complete implementation would
require a multipass rendering method and is attempted in the
zcomploc-experimental branch.
According to testers feedback, fixes bugs in the following games:
- Baten Kaitos
- Baten Kaitos Origins
- 007: Everything or Nothing
- Ty the Tasmanian Tiger
- Tony Hawk's Pro Skater 3
And probably other games too.

In previous revisions of Dolphin, changing texture generation settings (via
GX_SetTexCoordGen for example) did not regenerate the vertex shader and flush
the vertices. Adding this flush should fix texture problems in a few game, for
example in Superman: Shadow of Apokolips:
