Visual Boy Advance - M

Game Boy Advance Emulator

Windows and Mac builds are in the releases tab.

Nightly builds are here.

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 to the same directory as the executable.

If you are having issues, try resetting the config file first, go to Help ->
Factory Reset


The basic formula to build vba-m is:

Code: Select all

cd ~ && mkdir src && cd src
git clone
cd visualboyadvance-m

# ./installdeps will give you build instructions, which will be similar to:

mkdir build && cd build
cmake .. -G Ninja

./installdeps is supported on MSys2, Linux (Debian/Ubuntu, Fedora, Arch,
Solus, OpenSUSE, Gentoo and RHEL/CentOS) and Mac OS X (homebrew, macports or

Building a Libretro core

Clone this repo and then,

Code: Select all

cd src/libretro
make -j`nproc`

Copy 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

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:

Code: Select all

mkdir build
cd build
cmake .. -DVCPKG_TARGET_TRIPLET=x64-windows-static -DCMAKE_BUILD_TYPE=Debug -G Ninja


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 (optional, 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-gw64-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:

Code: Select all

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:

Code: Select all

cmake .. -DCMAKE_BUILD_TYPE=Debug -G Ninja

Here is the complete list:

CMake OptionWhat it DoesDefaults
ENABLE_WXBuild the wxWidgets portON
ENABLE_DEBUGGEREnable the debuggerON
ENABLE_NLSEnable translationsON
ENABLE_ASMEnable the following two ASM optionsON for 32 bit builds
ENABLE_ASM_SCALERSEnable x86 ASM graphic filtersON for 32 bit builds
ENABLE_MMXEnable MMXON for 32 bit builds
ENABLE_LINKEnable GBA linking functionality (requires SFML)AUTO
ENABLE_FFMPEGEnable ffmpeg A/V recordingAUTO
ENABLE_ONLINEUPDATESEnable online update checksON
ENABLE_LTOCompile with Link Time Optimization (gcc and clang only)ON for release build
ENABLE_GBA_LOGGINGEnable extended GBA loggingON
ENABLE_DIRECT3DDirect3D rendering for wxWidgets (Windows, NOT IMPLEMENTED!!!)ON
ENABLE_XAUDIO2Enable xaudio2 sound output for wxWidgets (Windows only)ON
ENABLE_OPENALEnable OpenAL for the wxWidgets portAUTO
ENABLE_SSPEnable gcc stack protector support (gcc only)OFF
ENABLE_ASANEnable libasan sanitizers (by default address, only in debug mode)OFF
UPSTREAM_RELEASEDo some release tasks, like codesigning, making zip and gpg sigs.OFF
VBAM_STATICTry link all libs statically (the following are set to ON if ON)OFF
SDL2_STATICTry to link static SDL2 librariesOFF
SFML_STATIC_LIBRARIESTry to link static SFML librariesOFF
FFMPEG_STATICTry to link static ffmpeg librariesOFF
SSP_STATICTry to link static gcc stack protector library (gcc only)OFF except Win32
OPENAL_STATICTry to link static OpenAL librariesOFF
SSP_STATICLink gcc stack protecter libssp statically (gcc, with ENABLE_SSP)OFF

Note for distro packagers, we use the CMake module
to configure installation directories.

MSys2 Notes

To run the resulting binary, you can simply type:

Code: Select all


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.:

Code: Select all

int foo = 42;
wxLogDebug(wxT("the value of foo = %d"), foo);

From the core etc. the usual:

Code: Select all

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:

Code: Select all

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:

Code: Select all

ulimit -c unlimited

in your shell to enable coredump files.


explains how to retrieve core dump on Fedora Linux (and possibly other

Once you have the core dump file, open it with gdb, for example:

Code: Select all

gdb -c core ./visualboyadvance-m

In the gdb shell, to print the backtrace, type:

Code: Select all


This may be a bit of a hassle, but it helps us out immensely.

Some of the shortcomings of this markdown mod is that it doesn't support doctoc and syntax highlighting, might need to see about adding certain markdown features as we see fit. But overall... Not terrible and it does the job fairly well.
