# Visual Boy Advance - M
Game Boy and Game Boy Advance Emulator
The forums are [here](https://board.visualboyadvance-m.org/).
Windows and Mac builds are in the [releases tab](https://github.com/visualboyadvance-m/visualboyadvance-m/releases).
Nightly builds for Windows and macOS are at [https://nightly.visualboyadvance-m.org/](https://nightly.visualboyadvance-m.org/).
**PLEASE TEST THE NIGHTLY OR MASTER WITH A FACTORY RESET BEFORE REPORTING
ISSUES**
Your distribution may have packages available as well, search for
`visualboyadvance-m` or `vbam`.
It is also generally very easy to build from source, see below.
If you are using the windows binary release and you need localization, unzip
the `translations.zip` to the same directory as the executable.
If you are having issues, try resetting the config file first, go to `Help ->
Factory Reset`.
## System Requirements
Windows XP, Vista, 7, 8.1 or 10/11, Linux distros or macOS.
2Ghz x86 (or x86-64) Intel Core 2 or AMD Athlon processor with SSE, Snapdragon 835
or newer CPU compatible with Arm for Windows.
- Just a guideline, lower clock speeds and Celeron processors may be able to run at full
speed on lower settings, and Linux based ARM Operating systems have wider CPU support.
DirectX June 2010 Redist
[Full](https://www.microsoft.com/en-au/download/details.aspx?id=8109) /
[Websetup](https://www.microsoft.com/en-au/download/details.aspx?id=35) for
Xaudio (Remember to uncheck Bing on the websetup.)
## Building
The basic formula to build vba-m is:
```bash
cd ~ && mkdir src && cd src
git clone https://github.com/visualboyadvance-m/visualboyadvance-m.git
cd visualboyadvance-m
./installdeps # On Linux or macOS
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -G Ninja
ninja
```
`./installdeps` is supported on MSYS2, Linux (Debian/Ubuntu, Fedora, Arch,
Solus, OpenSUSE, Gentoo and RHEL/CentOS) and Mac OS X (homebrew, MacPorts or
Fink.)

## Building a Libretro core
Clone this repo and then,
```bash
cd src/libretro
make -j`nproc`
2019-07-23 11:24:59 +00:00
```
Copy `vbam_libretro.so` to your RetroArch cores directory.
## Visual Studio Support
auto deps for visual studio, take 1 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.

For visual studio, dependency management is handled automatically with vcpkg,
cmake: Visual Studio support improvements. Add support for vcpkg ffmpeg, this requires using someone's FindFFmpeg.cmake instead of relying on pkg-config, since vcpkg does not have pkg-config. Do not use the ffmpeg from vcpkg on appveyor however, because that pushes the build cache generation over the time limit for jobs. Add secur32 and bcrypt to the list of ffmpeg libs on windows, these are standard windows libraries. Change some code in ffmpeg.cpp to remove C-style casts of struct initializers, which are illegal in MSVC. Add the INT64_C and UINT64_C macros missing in MSVC's stdint.h (if not defined) to ffmpeg.h before the ffmpeg headers are included, because they rely on them. Rewrite the wxWidgets finding code for the vcpkg wxWidgets to be nicer and work correctly for debug and static builds. Remove all /W* and /w* warnings options from cmake compiler flags, and replace them with /W4 for debug builds, and /w (no warnings) for release modes. When building a static binary, remove all /MD* flags from cmake compiler flags, and use /MT for static release builds and /MTd for static debug builds. Improve the vcpkg toolchain wrapper to only rebuild the vcpkg binary if there were git updates. Redo the handling of SDL2 and SDL_main. Only link SDL2Main to the SDL binary and don't use the definitions. Update CMakeSettings.json to use Ninja and include static configurations. Use CMAKE_PROJECT_DIR instead of CMAKE_SOURCE_DIR to determine the vcpkg root, as CMAKE_SOURCE_DIR is sometimes set incorrectly in the 2017 GUI. Add /nodefaultlib:libcmt to the debug build link flags, as in debug builds libcmtd is used and libcmt should not be. Add /subsystem:console to debug build link flags to produce a windows console app for debug builds, like we do for mingw builds. To do this, define a WIN32_CONSOLE_APP macro and if set, define a main() that calls WinMain(). Call wxMesdsageOutput::Set() in OnInit with an instance of wxMessageOutputStderr for windows debug builds to make sure the --help text etc. goes to the console instead of a popup box. Update the Visual Studio related text in README.md. Fix dynamic debug builds by linking to the debug version of SDL2 and copying the debug version of the dll to the build dir. Fix issue in MainFrame::BindAppIcon with the function we are using not being found in a Windows DLL in debug builds by using wxDynamicLibrary::GetSymboolAorW() instead of GetSymbol(). Enable LTO for MSVC in Release modes, if the option is set. Change appveyor config to use an 8 item build matrix of x64/x86 / Release/Debug / Static/Dynamic. And test the binary in debug modes by running --help. When copying the wxrc.exe out of the build tree, copy both the release and debug versions, this is so that appveyor caching of vcpkg works, since the build trees are not cached. Add some necessary win32 libraries to the SDL binary. And enable building it on appveyor. Fix #465. Signed-off-by: Rafael Kitover <rkitover@gmail.com>

From the Visual Studio GUI, just clone the repository with git and build with
the cmake configurations provided.
If the GUI does not detect cmake, go to `File -> Open -> CMake` and open the
`CMakeLists.txt`.
If you are using 2017, make sure you have all the latest updates, some issues
with cmake projects in the GUI have been fixed.
You can also build from the developer command prompt or powershell with the
environment loaded.

Using your own user-wide installation of vcpkg is supported, just make sure the
environment variable `VCPKG_ROOT` is set.
To build in the Visual Studio `x64 Native Tools Command Prompt`, use something
like this:
```
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -G Ninja
ninja
```
.
## Visual Studio Code Support
Make sure the
[C/C++](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools)
and [CMake
Tools](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cmake-tools)
extensions are installed.
Add the following to your `settings.json`:
```json
{
"cmake.configureOnOpen": true,
"cmake.preferredGenerators": [ "Ninja" ]
}
```
.
## Dependencies
If your OS is not supported, you will need the following:
2017-08-14 20:56:54 +00:00
- C++ compiler and binutils
- [make](https://en.wikipedia.org/wiki/Make_(software))
- [CMake](https://cmake.org/)
- [git](https://git-scm.com/)
- [nasm](https://www.nasm.us/) (optional, for 32 bit builds)
And the following development libraries:
2017-08-14 20:56:54 +00:00
- [zlib](https://zlib.net/) (required)
- [mesa](https://mesa3d.org/) (if using X11 or any OpenGL otherwise)
- [ffmpeg](https://ffmpeg.org/) (optional, at least version `4.0.4`, for game recording)
- [gettext](https://www.gnu.org/software/gettext/) and gettext-tools
- [SDL2](https://www.libsdl.org/) (required)
2017-08-14 20:56:54 +00:00
- [SFML](https://www.sfml-dev.org/) (optional, for link)
- [openal-soft](https://kcat.strangesoft.net/openal.html) (required, a sound interface)
- [wxWidgets](https://wxwidgets.org/) (required for GUI, 2.8 and non-stl builds are no longer supported)
On Linux and similar, you also need the version of GTK your wxWidgets is linked
to (usually 2 or 3) and the xorg development libraries.
Support for more OSes/distributions for `./installdeps` is planned.
## Cross compiling for 32 bit on a 64 bit host
`./installdeps m32` will set things up to build a 32 bit binary.
This is supported on Fedora, Arch, Solus and MSYS2.
## Cross Compiling for Win32
`./installdeps` takes one optional parameter for cross-compiling target, which
may be `win32` which is an alias for `mingw-w64-i686` to target 32 bit Windows,
or `mingw-w64-x86_64` for 64 bit Windows targets.
The target is implicit on MSYS2 depending on which MINGW shell you started (the
value of `$MSYSTEM`.)
On Debian/Ubuntu this uses the MXE apt repository and works quite well.
## CMake Options
The CMake code tries to guess reasonable defaults for options, but you can
override them, for example:
2017-08-14 20:56:54 +00:00
```shell
cmake .. -DCMAKE_BUILD_TYPE=Release -DENABLE_LINK=NO -G Ninja
```
. Here is the complete list:
| **CMake Option** | **What it Does** | **Defaults** |
|-----------------------|----------------------------------------------------------------------|-----------------------|
| `ENABLE_SDL` | Build the SDL port | OFF |
| `ENABLE_WX` | Build the wxWidgets port | ON |
| `ENABLE_DEBUGGER` | Enable the debugger | ON |
| `ENABLE_ASM_CORE` | Enable x86 ASM CPU cores (**BUGGY AND DANGEROUS**) | OFF |
| `ENABLE_ASM` | Enable the following two ASM options | ON for 32 bit builds |
| `ENABLE_ASM_SCALERS` | Enable x86 ASM graphic filters | ON for 32 bit builds |
| `ENABLE_MMX` | Enable MMX | ON for 32 bit builds |
| `ENABLE_LINK` | Enable GBA linking functionality (requires SFML) | AUTO |
| `ENABLE_LIRC` | Enable LIRC support | OFF |
| `ENABLE_FFMPEG` | Enable ffmpeg A/V recording | AUTO |
| `ENABLE_ONLINEUPDATES` | Enable online update checks | ON |
| `ENABLE_LTO` | Compile with Link Time Optimization (gcc and clang only) | ON for release build |

| `ENABLE_ASAN` | Enable libasan sanitizers (by default address, only in debug mode) | OFF |
| `UPSTREAM_RELEASE` | Do some release tasks, like codesigning, making zip and gpg sigs. | OFF |
| `BUILD_TESTING` | Build the tests and enable ctest support. | ON |
| `VBAM_STATIC` | Try link all libs statically (the following are set to ON if ON) | OFF |
| `SDL2_STATIC` | Try to link static SDL2 libraries | OFF |
| `SFML_STATIC_LIBRARIES` | Try to link static SFML libraries | OFF |
| `FFMPEG_STATIC` | Try to link static ffmpeg libraries | OFF |
| `OPENAL_STATIC` | Try to link static OpenAL libraries | OFF |
| `TRANSLATIONS_ONLY` | Build only the translations.zip and nothing else | OFF |
Note for distro packagers, we use the CMake module
[GNUInstallDirs](https://cmake.org/cmake/help/v2.8.12/cmake.html#module:GNUInstallDirs)
to configure installation directories.
On Unix to use a different version of wxWidgets, set
`wxWidgets_CONFIG_EXECUTABLE` to the path to the `wx-config` script you want to
use.
## Reporting Crash Bugs
If the emulator crashes and you wish to report the bug, a backtrace made with
debug symbols would be immensely helpful.
To generate one (on Linux and MSYS2) first build in debug mode by invoking
`cmake` as:
```shell
cmake .. -DCMAKE_BUILD_TYPE=Debug
```
After you've reproduced the crash, you need the core dump file, you may need to
do something such as:
```shell
ulimit -c unlimited
```
, in your shell to enable core files.
[This
post](https://ask.fedoraproject.org/en/question/98776/where-is-core-dump-located/?answer=98779#post-id-98779)
explains how to retrieve core dump on some distributions, when they are managed
by systemd.
Once you have the core file, open it with `gdb`, for example:
```shell
gdb -c core ./visualboyadvance-m
```
. In the `gdb` shell, to start the process and print the backtrace, type:
```
run
bt
```
. This may be a bit of a hassle, but it helps us out immensely.
