Make `speedup_frame_skip` and `speedup_throttle` independent settings,
with `speedup_frame_skip == 0` when `speedup_throttle` is not in effect,
and `speedup_throttle == 100` when `speedup_frame_skip` is in effect.
This fixes a previously introduced bug where `speedup == true &&
speedup_frame_skip = X` was never enabled.
This also allows `speedup_throttle == 0` for no throttle and no frame
skip during speedup.
Also set the upper bound on `throttle` and `speedup_throttle` to `450`
instead of `600`, as the DirectSound driver does not support values
higher than that.
In the DirectSound implementation of `setThrottle`, for `throttle == 0`
use a `throttle == 450` frequency multiplier, because a zero frequency
does nothing.

Stereo buffer is not remade in the case of audio plugin
switch (only affects GBA, not GB). This results in a crash.
We need to remake the stereo buffer and reinit the pointers
in Gba_Pcm.output or they will be dangling, and lead to a
crash. Also, cleaning up the Multi_Buffer class a bit.
- Allow key shortcuts to run with loaded game.
For example, when we set `CTRL+A` for `load most recent save state` and
use `A` for some input command, holding `CTRL` and then pressing `A`
will not execute the shortcut. Instead, the key press `A` will be used
only as the input and nothing else.
With this, we use both the input and shortcut key.
- Isolate function to get keyboard key codes.
As explained on [1]:
"Using `GetUnicodeKey()` is in general the right thing to do if you are
interested in the characters typed by the user, `GetKeyCode()` should
be only used for special keys (for which `GetUnicodeKey()` returns
`WXK_NONE`)."
We also allow special keys to be mapped, hence the requirement of using
both functions.
[1] https://docs.wxwidgets.org/3.1/classwx_key_event.html
- Allow use of unicode keys for input and shortcut.
Use format `KeyCode:Modifier` for saving/loading unicode keys.
`WxWidgets=3.{0,1}` does not create an accelerator from strings with
unicode keys such as `ç` (`FromString` function). It fails with an
assertion error and stops execution. At the same time, we use the keys'
strings that are known for WxWidgets, such as `A`, `CTRL+O`,
`PAGEUP` etc.
Use both `EVT_KEY_DOWN` and `EVT_CHAR`.
`EVT_CHAR` is better than `EVT_KEY_DOWN` here because it is where the
raw key events will have been cooked using whatever recipes are in
effect from the os, locale, international keyboard settings, etc.
- Enable SDL joysticks input as key shortcuts.
Start/Stop polling joysticks on Unload/load game.
Our main loop already polls the joystick, we don't need the timer
while a game is running.
- Create function `str_split_with_sep` and use it.
For when we parse strings that may include the sep string, such as
game input and key shortcuts.
It is not needed to set `throttle` on neither case. There is actually a
bug when using turbo/speedup and closing the emulator. The test case
is the following:
https://github.com/visualboyadvance-m/visualboyadvance-m/issues/627
On Windows:
1. use opengl;
2. load GBA game;
3. set throttle to `100%`;
4. set turbo throttle to `200%`;
5. enable turbo on menu;
6. save game;
7. close emulator && open emulator;
8. load GBA game;
==>
throttle is `200%`.
This is definitely not expected.
In the Turbo config dialog, remove the selection list for entering the
value and leave only the spin control. Allow values above 600%, up to
4000%.
Reintroduce the speedup_frame_skip config variable, defaulting to 9, use
it for turbo selection values > 600%, with speedup_throttle == 0.
The rationale for this is that on average modern hardware, throttle
values above 500% or 600% will not be effective.
The default is now shown as 1000%, which is:
frame_skip == 9 && speedup == 1,
where:
speedup == 1 is equivalent to throttle == 0,
as was the case before the turbo config changes.
Values above 600% are automatically rounded up or down to the nearest
100%, on entry and on click of the up/down arrows of the spin control.
The frame skip checkbox is cleared and disabled for the "Unlimited"
setting (throttle == 0), and set and disabled for values > 600%, to
reflect the mechanism to the user.
When the value again enters the modifiable range in the spin control,
the previous value of the checkbox is restored.
Misc:
- Turn off translation of percentage values in the xrc.
- Remove the size element for the throttle selection list in the general
config dialog xrc, it breaks the layout on GTK3.
- Add a note about passing wxWidgets_CONFIG_EXECUTABLE to cmake to
select wxWidgets version to README.md.
Hopefully this will reduce confusion and present a nicer UI.

We have some issues when trying to open files on Windows that contains
characters not included in the current codepage. Using `fopen` fails
when that happens.
One example is using the `pt_BR` codepage and then using a name with
japanese chars for the battery file.
The games and BIOS work since they use `blargg_open`. It converts a
`const char *` to `const wchat_t *` and uses `_wfopen` for windows.
(doing a multibyte to widechar conversion)
Since we want to avoid doing many code changes on our cores, we need
some `util*` functions for the matter.
Replace `mb_fn_str` by UTF-8 strings.
Replace all occurrences of `fopen` for `utilOpenFile` on GBA core.
Replace all occurrences of `fopen` for `utilOpenFile` on GBA e-reader.
Adjust e-readers calls on wx frontend.
Replace all occurrences of `fopen` for `utilOpenFile` on Patcher files.
Always apply UTF-8 when dealing with path strings.
On our wx frontend we should always send UTF-8 `char *` to our cores
functions. This way we can have consistency when dealing with them for
each platform.
On Windows, we will convert all multibyte to wide chars and use proper
functions for I/O operation.
Create function to deal with unicode calls of `gzopen`.
We use `gzopen_w` (`zlib>=1.27`).
Replace all occurrences of `fopen` for `utilOpenFile` on Config Manager.
Replace all occurrences of `fopen` for `utilOpenFile` on Cheat files.
Use proper functions for unicode on GB core.
Use function instead of macro for `UTF8()`.
Use `nullptr` instead of `NULL`.
Print wide char strings on status bar.
Fix throttle=0 (unlimited speed) settings for both the Speedup/Turbo
config panel and the general throttle setting and make 100 the default.
Replace the speedup frame skip option with a "Frame skip" checkbox,
which enables skipping the appropriate number of frames if vsync or very
low system performance is in effect. The systemFrameSkip (under video
config) is added to this value.
With speedup_throttle=100, the old speedup behavior is used with 9
frames skipped.
With speedup_throttle == 0 && speedup_throttle_frame_skip, skip 9
frames at full speed, which is exactly the same as the old behavior,
since throttle == 0 is equivalent to speedup == true.
Hopefully these changes will make the turbo config dialog more useful
for users, by default frame skipping to work around vsync will be
enabled, and users can uncheck the "Frame skip" checkbox for a smoother
experience.

When we skip frames, we just don't draw them on our frontend. The
function `systemDrawScreen` also send the video frames to be recorded,
but only when called from the core.
Our solution creates a auxiliary `systemSendScreen` that only adds the
frame to the recording. It is called when the core decides to skip a
frame. This way we can get the video frame for recording, just like
audio ones are always sent.
For the netlink dialog, leave the server IP text field enabled when the
server radio button is selected and bind it to the new option
gopts.server_ip which defaults to "*" for binding on all addresses,
which was the previous behavior.
Copy this value to the new GBALink global IP_LINK_BIND_ADDRESS and use
it when creating a listening socket.
SFML supports creating sf:IpAddress values from hostnames, consequently
no additional code is needed to support hostnames in the netlink dialog.
Change GetLinkServerHost to return the primary local address when the
value is "*", which was the previous behavior, and the set value
otherwise.
Remove the min/max macros from GBALink as they are unnecessary and
conflict with std headers.
Require at least SFML 2.4 instead of 2.x for the IP binding
functionality in cmake.

soundInit() returns a bool to indicate success, and failure inevitably
leads to crashes as the emulator tries to use a NULL soundDriver.
On false, popup an error dialog saying that the sound driver failed to
initialize, this is at least better than crashes, which will also need

We need to use proper documented behaviour when coding the
core, therefore this should be reverted until a proper
solution is done.
This reverts commit ca3b63d64c.
The current code is very messy as far as GFX goes. There are more
elegant ways of tackling this issue, but they are very difficult with
our current code.
The idea behind this issue is that the backgrounds are not switching
properly for the lcd. So we enable the layers accordingly to
`layerSettings & DISPCNT` on every `CPUUpdateRenderBuffers`.
The bits of `layerSettings` enconde each layer and objs.
We actually only need 2 of these, but I can't do much more here
unsupervised.
- Fix#376.
Although a length check is being performed on the imported GSA Codes file, `len` is both a signed int and attacker controlled.
With a specially crafted GSA Codes file, an attacker could specify a value for `len` that overflows the `int` type, rolling over into a negative number. By doing so, the attacker can bypass the conditional mentioned above.
The `fseek` length parameter is of type `size_t` which is an unsigned int, this will result in `len` being interpreted as a large unsigned int, allowing for a stack based buffed overflow in the desc char array.
By making `len` an unsigned integer, it will prevent the overflow. It ensures that the bounds check works as intended.
We protect all code relevant to disabling this property with either
`BKPT_SUPPORT` or `NO_DEBUGGER`. This is mostly debugging options or
prints scattered around the code.
We also adjust cmake to ignore the specific files surround it, but
allowing the rest of the GUI to work.
- Fix#431.
Use `/std:c++latest` for Visual Studio because the XBRZ 1.7 code
requires at least C++17.
Replace the use of `bool++` in `GBALink.cpp` which is now apparently an

Use `/W4` to enable a good amount of warnings in Debug mode, and `/W0`
to disable warnings entirely in release modes.

Similar update to GBA which does the following:
- reduces input lag by 1 frame by reading user input at beginning of cpu loop
- audio and video timing update, which sends audio and video at every frame possible
- add missing sound state variable, soundTicks for gb and gba
Make some changes to support out-of-the-box builds on FreeBSD:
- set cmake OpenGL type to `LEGACY`, the new `GLVND` type produces
unusable binaries on FreeBSD
- on FreeBSD add -I/usr/local/include to compiler flags, why this is
necessary I don't know
- look for llvm tools such as `llvm-ar` in `/usr/local/llvm-devel/bin`,
LTO works
- improve the `find_wx_util()` cmake function to handle `wx-config`
scripts named in the form e.g. `wxgtk3u-3.1-config`
- add FreeBSD support to `installdeps`
- make some minor changes to included headers based on macros such as
`__FreeBSD__` to compile on FreeBSD, including adding a `BSD.h` header
with some defines for e.g. `fseeko64`
- move the cmake X11 detection to before the wx compile tests, because
otherwise the extra compile flags for the wx tests make the X11 tests
fail
- make some minor changes to fix wx 2.8 compatibilty again, we don't
actually use 2.8 for FreeBSD but I was testing it

Use vcpkg to build deps when Visual Studio on Windows is detected, this
only happens on first build, but does take a while because things like
wxWidgets need to be built. Building from the developer command line is
also supported.
I considered making a pre-built tarball available, but the resulting
files are just too big for this to be practical.
Make the necessary cmake code changes for this to work and to use the
vcpkg packages, which work just like on linux or have other cmake glue
code available.
To do this, we make vcpkg a submodule, use git to checkout all
submodules, then just build and use the `vcpkg.exe`. Then we set the
CMAKE_TOOLCHAIN_FILE to the vcpkg toolchain and also include it
directly, why this is necessary I don't know, without it it doesn't work
in the IDE but does on the command line.
All of this requires no vcpkg integration with either the user or the
project. A user-wide `ENV{VCPKG_ROOT}` is also supported.
Fix the dynamic arrays in the GBA core, MSVC follows the C++ standard on
this and gcc does not.
TODO: add the necessary gcc flags to make this an error in cmake.
Use `wxArrayString` instead of `std::vector<wxString>` in
`src/wx/strutils.cpp` which is used in options parsing. This was
necessary because of a bizarre linker error with wxWidgets when using
Visual Studio:
https://trac.wxwidgets.org/ticket/10884#comment:46
In `src/wx/panel.cpp` make sure the unimplemented D3D renderer code does
not get compiled if it's actually `OFF`.
Also fix the new spacer code for the drawing panel to not combine
`wxEXPAND` with `wxALIGN_CENTER`, which is an error on wxWidgets 3.1.2,
which is what vcpkg uses. The drawing panel seems to be automatically
stretched to the max size automatically anyway.
TODO: if all of this works, we'll need an Appveyor set up for visual
studio.

Add Speedup / Turbo configuration panel which allows setting the
throttle or number of frames to skip for when the speed key is pressed
or turbo is enabled (which just presses the speed key.)
Throttle and frame-skip are mutually exclusive, throttle must be 0 (no
throttle) when number of frames to skip is non-zero. The dialog controls
handle this.
This is implemented in the core in GBA.cpp, GB.cpp and ConfigManager.
Two new options are added both in ConfigManager and in the wx options,
speedup_throttle and speedup_frame_skip, the defaults are:
```
speedup_throttle = 0 (no throttle)
speedup_frame_skip = 9
```
this was the original behavior.
Add support for unsigned ints to wx/opts.cpp for these and for throttle,
this requires a new validator wxUIntValidator to use them in spin
controls.
Clean up appearance of the throttle spin control in the General dialog.
Maximum throttle and speedup_throttle is 600, values much over 500 will
not behave differently from 0 on modern hardware.
Maximum frame skip is 30 at the moment.

1. EEPROM: move eepromInUse and eepromSize from EepromReset() to eepromInit()
to avoid re-initializing during a reset (makes item below redundant)
2. Remove gbaSaveType variable - this is now redundant due to change above
which probably was added for this reason since games using eeprom fails with
gamepak error after a reset.
3. Add labels to identify cpuSaveTypes
4. libretro: remove workaround for eeprom reset issue (#1), do not apply
custom gbPalettes if not running in GB, change vram size to 0x18000 in
memory map
