In some Triforce games (e.g. _F-Zero AX_), the bytes that follow the
region flag in the `boot.id` file (at `0x38`) happen to be `0x00`.
However, in other games (e.g _Mario Kart Arcade GP 2_), it seems the
region flag is padded with `0xFF`.
_Mario Kart Arcade GP 2_ (`boot.id` in the USA version):
```
00000 0000: 42 54 49 44 00 00 01 E0 00 00 00 01 00 00 00 01 BTID.... ........
00000 0010: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF ........ ........
00000 0020: 47 43 41 4D 00 00 01 C0 07 D3 05 0F 00 00 00 07 GCAM.... ........
00000 0030: 53 42 4E 4C 00 00 00 00 0E FF FF FF FF FF FF FF SBNL.... ........

region flag
```
When the region flag was tested in `switch` statements (where a single
byte was expected in the `case`s), the test would fail, depending
on the game.
This issue would lead to the wrong calculation of the country in
`VolumeDisc::GetCountry()`, which was then used to build the game ID in
`VolumeDisc::GetGameID()`.
The solution is to test using only the least meaningful byte in the
region flag.
Unexpected game IDs were first noticed with USA version of _Mario Kart
Arcade GP 2_, which was wrongly assigned the same game ID that is given
to the Japan version (i.e. `GNLJ82`). The correct game ID for the USA
version is `GNLE82`.
Check the return value of calls to `GetBuffer` and stop the `WASAPI
handler` sound thread if they fail.
This prevents a crash due to a null pointer dereference if `GetBuffer`
is unable to retrieve a buffer, which could be triggered during
emulation by disabling the selected WASAPI output device in the Windows
Sound settings.
The status bar shows the number of games in your collection. If any
games are hidden by the platform, region, or search filters it will also
show how many games are visible and how many are filtered.
The visibility of the status bar can be toggled from the menu by
selecting `View`->`Show Game Count`.

Reasons:
- Only 0.000341% of all Android users were on API 21-23 in the last 365 days.
- These devices are old and likely do not run Dolphin well.
- Android 5.x and 6.0 have been without security updates for about 8 years.
- Staying on API 21–23 blocks AndroidX updates, including Lifecycle.
