Closes emulator issue #10186
This adds Vertex Rounding to the Sonic Heroes' GameINI (allowing you enjoy Sonic Heroes in higher resolution without problem) and then removed the forced 1x Native and Anti-Aliasing settings as they are not needed when Vertex Rounding is enabled.
This will avoid effects being unexpectedly broken in these games if the user disables the option globally. This list is by no means comprehensive, these are just the games I could confirm use custom mipmaps.
Work around a dcache issue by preventing the game from doing
something pointless.
The game's DVD read function writes 0x87654321 to the entire read
buffer and 0x12345678 to the last 4 bytes. It then calls DVDReadAsync()
and without waiting for the read to complete at all, it checks if the
last 4 bytes are still 0x12345678. If they are, then the game fails.
The check always passes on console because DVDReadAsync() calls
issueCommand(), which calls DCInvalidateRange(read_buffer) (dcbi).
Dolphin cannot emulate this without an extremely significant
performance hit.
Forcing people to use hacks is a bad idea in general, and there are
two practical problems with doing it for immediate XFB in particular:
1. It breaks the GC IPL, which some users run when launching games.
2. Competitive players don't necessarily want the lowest possible
latency - they might want the latency that's the closest to console,
so if they're playing locally with a low-latency monitor, they might
not want to use immediate XFB. (This isn't a theoretical concern -
I've seen Melee players want to increase their latency.)
Besides, it feels arbitrary that just these five specific games should
have immediate XFB forced on.
This reverts commit 1fc910b3ea,
replacing the old INI setting EFBScale with a new INI setting
called InternalResolution, which has a simpler mapping:
| EFBScale | InternalResolution
----------------- | -------------------- | --------------------
Auto (fractional) | 0 |
Auto (integral) | 1 | 0
1x | 2 | 1
1.5x | 3 |
2x | 4 | 2
2.5x | 5 |
3x | 6 | 3
4x | 7 | 4
5x | 8 | 5
6x | 9 | 6
All the fractional IRs were removed in f090a943.
Without virtual xfb, the game will show distorted graphics once leaving
the title screen. This adds an INI file to make the game playable.
The wiki page for this game also notes the need for virtual xfb.
This could cause the first branch of the bootucode procedure, which
takes its parameters from the AX registers, to run during the ROM init
sequence. Since the ROM doesn't set any of the AX registers, the values
aren't meaningful, and can cause bad DMA transfers and crashes.
Wii.Widescreen is a setting that cannot be changed on the fly after
emulation has started, so anything booted after the initial title
will have an unexpected aspect ratio.
We can just set Video_Settings.AspectRatio instead, which *can* be live
changed, since it doesn't involve messing with the SYSCONF at any time.
This is also much closer to the behaviour of the Wii U, which
configures the DMCU to force 4:3 transparently, instead of doing it the
intrusive way (touching the SYSCONF).
Based off codehandleronly.bin. Improves support for codes with conditionals due to adding cache invalidation on stores. You also have support for mode code lines at once before Dolphin freezes at startup.
- coef: Explicitly set 23 different values that are used by GBA UCode,
and tweaked overall parameters to more closely match those 23 values.
- irom: Moved a few functions to their proper places, updated BootUCode
to configure DMA transfers using AX registers as well as IX registers
(the GBA UCode uses this to do two sequential transfers in one call),
and added partial functions used by GBA UCode.
All functions were reverse-engineered solely based off of observed
effects on the virtual machine: register states before-and-after, dmem
interactions, and DMA transfers. The specific coefficients were observed
being read from dmem, and must be exactly those values to function
properly. I have no knowledge of how the official ROM implements these
functions, or how it is implemented overall.
Tested with The Legend of Zelda: Four Swords Adventures, Final Fantasy
Crystal Chronicles, and Billy Hatcher and the Giant Egg (to download
ChuChu Rocket!).
This adds new themed rating stars to all of the theme folders, with the
intent to eventually replace the awful old ratings stars in
sys/resources. I’m not a coder so it will be up to someone else to use
these files to replace the ratings stars in WX and Qt. Their dimensions
are the same as the old ones, so it should be pretty easy to implement,
though it will require moving over to theme-able files and supporting
HiDPI for them.
@4x files are present for future proofing / possible android usage.
All files have been optimized with opti-png.
This allows us to print user friendly names for titles out of the box,
without requiring the user to manually download a title database and
place it in the correct location.
No auto-update mechanism is implemented as it would be substantially
more complicated and overkill (imo), since titles are not updated
that often. I have however added a script to make updating them easier.
The database can be freely used without any restriction. I have
contacted the author.
Dolphin is able to generate one with all correct default settings, so
we don't need to ship with a pre-generated SYSCONF and worry about
syncing default settings.
Additionally, this commit changes SysConf to work with session SYSCONFs
so that Dolphin is able to generate a default one even for Movie/TAS.
Which SYSCONF needs to be touched is explicitly specified to avoid
confusion about which file SysConf is managing.
(Another notable change is that the Wii root functions are moved into
Core to prevent Common from depending on Core.)
