Our bridged Discord server is Here.
We are also on #vba-m on Libera IRC which has a Web
Chat.
Want to know where you can install visualboyadvance-m in your linux distribution?
Visual Boy Advance - M
Game Boy and Game Boy Advance Emulator
The forums are here.
Windows and Mac builds are in the releases tab.
Nightly builds for Windows and macOS are at 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.
Building
The basic formula to build vba-m is:
cd ~ && mkdir src && cd src
git clone https://github.com/visualboyadvance-m/visualboyadvance-m.git
cd visualboyadvance-m
./installdeps
# ./installdeps will give you build instructions, which will be similar to:
mkdir build && cd build
cmake .. -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,
cd src/libretro
make -j`nproc`
Copy vbam_libretro.so to your RetroArch cores directory.
Visual Studio Support
For visual studio, dependency management is handled automatically with vcpkg, 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 command prompt, use something like this:
mkdir build
cd build
cmake .. -DVCPKG_TARGET_TRIPLET=x64-windows-static -DCMAKE_BUILD_TYPE=Debug -G Ninja
ninja
Visual Studio Code Support
Make sure the C/C++ and CMake Tools extensions are installed.
Add the following to your settings.json:
{
"cmake.configureOnOpen": true,
"cmake.preferredGenerators": [ "Ninja" ]
}
.
Dependencies
If your OS is not supported, you will need the following:
And the following development libraries:
- zlib (required)
- mesa (if using X11 or any OpenGL otherwise)
- ffmpeg (optional, at least version
4.0.4, for game recording) - gettext and gettext-tools (optional, with ENABLE_NLS)
- SDL2 (required)
- SFML (optional, for link)
- OpenAL or openal-soft (required, a sound interface)
- wxWidgets (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.
On Fedora it can build using the Fedora MinGW packages, albeit with wx 2.8, no OpenGL support, and no Link support for lack of SFML.
On Arch it currently doesn't work at all because the AUR stuff is completely broken, I will at some point redo the arch stuff to use MXE as well.
CMake Options
The CMake code tries to guess reasonable defaults for options, but you can override them, for example:
cmake .. -DENABLE_LINK=NO -G Ninja
Of particular interest is making Release or Debug builds, the default mode is Release, to make a Debug build use something like:
cmake .. -DCMAKE_BUILD_TYPE=Debug -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_NLS | Enable translations | 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_GBA_LOGGING | Enable extended GBA logging | ON |
| ENABLE_DIRECT3D | Direct3D rendering for wxWidgets (Windows, NOT IMPLEMENTED!!!) | ON |
| ENABLE_XAUDIO2 | Enable xaudio2 sound output for wxWidgets (Windows only) | ON |
| ENABLE_OPENAL | Enable OpenAL for the wxWidgets port | AUTO |
| ENABLE_SSP | Enable gcc stack protector support (gcc only) | OFF |
| 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 |
| SSP_STATIC | Try to link static gcc stack protector library (gcc only) | OFF except Win32 |
| OPENAL_STATIC | Try to link static OpenAL libraries | OFF |
| SSP_STATIC | Link gcc stack protecter libssp statically (gcc, with ENABLE_SSP) | OFF |
| TRANSLATIONS_ONLY | Build only the translations.zip and nothing else | OFF |
Note for distro packagers, we use the CMake 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.
MSys2 Notes
To run the resulting binary, you can simply type:
./visualboyadvance-m
in the shell where you built it.
If you built with -DCMAKE_BUILD_TYPE=Debug, you will get a console app and
will see debug messages, even in mintty.
If you want to start the binary from e.g. a shortcut or Explorer, you will need
to put c:\msys64\mingw32\bin for 32 bit builds and c:\msys64\mingw64\bin
for 64 bit builds in your PATH (to edit system PATH, go to Control Panel ->
System -> Advanced system settings -> Environment Variables.)
If you want to package the binary, you will need to include the MinGW DLLs it depends on, they can install to the same directory as the binary.
Our own builds are static.
Debug Messages
We have an override for wxLogDebug() to make it work even in non-debug builds
of wx and on windows, even in mintty.
It works like printf(), e.g.:
int foo = 42;
wxLogDebug(wxT("the value of foo = %d"), foo);
From the core etc. the usual:
fprintf(stderr, "...", ...);
will work fine.
You need a debug build for this to work or to even have a console on Windows.
Pass -DCMAKE_BUILD_TYPE=Debug to cmake.
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:
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:
ulimit -c unlimited
in your shell to enable coredump files.
This post explains how to retrieve core dump on Fedora Linux (and possibly other distributions.)
Once you have the core dump file, open it with gdb, for example:
gdb -c core ./visualboyadvance-m
In the gdb shell, to print the backtrace, type:
bt
This may be a bit of a hassle, but it helps us out immensely.
