Gecko codes are a core foundation of most netplay sessions and most general modding cases. It has gone so far as to now have an ini for almost every game.
After the massive UI overhaul, the gecko code sorting defaults to Alphabetical with no option to change it. This removes the possibility for netplay builds to have important and necessary codes at the top for easy selecting, and removes the ability to sort massive code lists in categories.
This will also make the sorting consistent with AR codes, which are sorted manually.
glBlitFramebuffer() does not bypass the scissor test, which meant that
part of texture copies (e.g. XFB) could have been clipped when running
under OpenGL ES, as glCopyImageSubData() is not supported.
floatindex is clamped to the range [0, 9]. For non-negative numbers
floor() is equivalent to trunc(). Truncation happens implicitly when
converting to uint, so the floor() is unnecessary.
These country codes have the unfortunate property that they are used
by Wii disc games in two different regions. We already correct for this
in VolumeGC::GetCountry and VolumeWii::GetCountry, so this commit
shouldn't really have any effect on how the game list behaves,
but it will be useful if we in the future would want to call
CountrySwitch directly without having extra code in the caller for
handling region weirdness.
This avoids out-of-bounds warnings when replaying FIFO captures.
The value of XF_REGS_SIZE is written into the DFF header and we only
read the min of XF_REGS_SIZE and the header value, so this change is
backward compatible and doesn't break forward compatibility for old
Dolphin versions either.
* Removed the Cancel button since the code doesn't react to it anyway.
* Only show a window title, not the help icon (?), and disable the close button
* Set the title to "Dolphin" instead of repeating the label text
The current approach results in the UI thread creating a graphics device
whilst the core is running, leading to races on function pointers, and
potentially crashing.
Prior to this commit, the emitter would unconditionally emit a 10-byte
instruction known as MOVABS when loading a 64-bit immediate to a
register.
0: 48 b8 ef be ad de 00 movabs rax,0xdeadbeef
7: 00 00 00
With this change, it will instead rely on the fact that on x64 writes to
32-bit registers are automatically zero extended to 64-bits, allowing
us to emit a 5 or 6-bytes instruction with the same effect for certain
immediates.
0: b8 ef be ad de mov eax,0xdeadbeef
Fixes a critical regression from 8bb08d1ca6.
In that commit, I replaced a 1024 byte buffer with a SHCIEventCommand.
However, it looks like some Bluetooth adapters actually require such
a large buffer, so this change needs to be reverted.
This fixes severe image flickering in some cutscenes of Twin Snakes. The game appears to sometimes load a previously made XFB copy as a texture before it is actually rendered to the screen, which we took as an invitation to invalidate the XFB copy.
Prior to this commit, the emitter would unconditionally emit a 10-byte
instruction known as MOVABS when loading a 64-bit immediate to a
register.
0: 48 b8 ef be ad de ff movabs rax,0xffffffffdeadbeef
7: ff ff ff
With this change, it will instead emit a 7-byte instruction when it is
possible to express the 64-bit immediate using a signed 32-bit value.
0: 48 c7 c0 ef be ad de mov rax,0xffffffffdeadbeef
If, for whatever reason, the XFB has to be loaded from console memory, it's possible that the texture is returned at native resolution instead of EFB-scaled resolution. In this case, our xfb_rect.right adjustment must also happen at native resolution instead of scaled resolution.
The header of a Wii disc can be read from two places: The
unencrypted area at the beginning of the disc, or the beginning of
the game partition. The two copies are usually identical (except
for 0x60 and 0x61), but there are exceptions. For most of Dolphin's
history, we have been reading from the header inside the game
partition when getting metadata. This was however not the case
starting with 4.0-4901 and ending with 5.0-3762. This commit once
again makes Dolphin read metadata from the unencrypted header,
because of the following reasons that I recently was informed about:
- The "pink fish" disc has the game ID 410E01 in the unencrypted
header but the placeholder game ID RELSAB in the partition header.
- The revisions of some games differ between the two headers,
with the unencrypted one making more sense.
(See https://bugs.dolphin-emu.org/issues/11387)
For better or worse, this also means that sloppily hacked games where
only the game ID in the unencrypted header has been changed now will
use that modified game ID. And unlike with the partition header,
there is no signing or hashing that can tell us whether the
unencrypted header has been modified by someone other than Nintendo.
Dolphin has traditionally treated the SI IO buffer (128 bytes) as a set of
32 little endian u32s. This works out fine if you only ever read/write
using aligned 32bit accesses. Different sized accesses or misaligned reads
will mess it up. Byte swapping reads/writes will fix this up, but all the
SI devices that use the SI IO buffer need to be adjusted.
