We already check ahead of time if the optional contains a value within
it before accessing it, so we don't need to use the throwing value()
accessor. We can just directly use operator->
Rather than construct strings twice, we can just construct it once and
reuse it. While we're at it, we can move variables closer to where
they're actually used within DownloadDefaultCover()
Because the GC language setting cannot be set to Japanese, we
need a special condition for Japanese GC games. I accidentally
removed it in PR 7816, but here it is again in a new form.
We could do the same thing with Korean GC games if we want to
(which we couldn't do before PR 7816), but due to how spotty
GameTDB is with having Korean names for Korean GC releases,
things will be more consistent if we just use English for them.
Instead of selecting languages based on the user config at the time
of TitleDatabase creation and merging the different languages into one
map for GC and one map for Wii, have one map for each language, and
have the caller supply the language they want. This makes us not need
the IsGCTitle function, which is inaccurate for IDs that start with D.
The difference between Dolphin's game IDs and GameTDB's game IDs
is that GameTDB uses four characters for non-disc titles, whereas
Dolphin uses six characters for all titles.
This fixes:
- TitleDatabase considering Datel discs to be NHL Hitz 2002
- Gecko code downloading not working for discs with IDs starting with P
- Cover downloading mixing up discs with channels (e.g. Mario Kart Wii
and Mario Kart Channel) and making extra HTTP requests. (Android was
actually doing a better job at this than DolphinQt!)
ChunkFile doesn't use any of the file utilities, so we can drop these
headers to avoid pulling in unnecessary dependencies. This also
uncovered a few indirect inclusions.
Deduplicates code, and gets rid of some problems the old code had
(such as: bad performance when calling native functions, only one
disc showing up for multi-disc games, Wii banners being low-res,
unnecessarily much effort being needed for adding more metadata).
The original reason I wanted to do this was so that we can replace
the Android-specific code with this in the future, but of course,
just deduplicating between DolphinWX and DolphinQt2 is nice too.
Fixes:
- DolphinQt2 showing the wrong size for split WBFS disc images.
- DolphinQt2 being case sensitive when checking if a file is a DOL/ELF.
- DolphinQt2 not detecting when a Wii banner has become available
after the game list cache was created.
Removes:
- DolphinWX's ability to load PNGs as custom banners. But it was
already rather broken (see https://bugs.dolphin-emu.org/issues/10365
and https://bugs.dolphin-emu.org/issues/10366). The reason I removed
this was because PNG decoding relied on wx code and we don't have any
good non-wx/Qt code for loading PNG files right now (let's not use
SOIL), but we should be able to use libpng directly to implement PNG
loading in the future.
- DolphinQt2's ability to ignore a cached game if the last modified
time differs. We currently don't have a non-wx/Qt way to get the time.
