Downloads

Downloads can be found on the official website, in the Downloads section. The source code can be found on GitHub.

Compiling

Compiling requires using CMake 2.8.11 or newer. To use CMake to build on a Unix-based system, the recommended commands are as follows:

mkdir build
cd build
cmake ..
make
make install

Dependencies that are installed will be automatically detected, and features that are disabled if the dependencies are not found will be shown at the end of the cmake command.

Dependencies

mGBA has no hard dependencies, however, the following optional dependencies are required for specific features. The features will be disabled if the dependencies can't be found.

Qt 5: for the GUI frontend. Qt Multimedia or SDL are required for audio.
SDL: for a more basic frontend and gamepad support in the Qt frontend. SDL 2 is recommended, but 1.2 is supported.
zlib and libpng: for screenshot support and savestate-in-PNG support.
libedit: for command-line debugger support.
ffmpeg or libav: for video recording. Libav is untested.
libzip: for loading ROMs stored in zip files.
ImageMagick: for GIF recording.

Footnotes

[1] Currently missing features are

OBJ window for modes 3, 4 and 5 (Bug #5)
Mosaic for transformed OBJs (Bug #9)
Cartridges with light sensors (Boktai: The Sun is in Your Hand and Boktai 2: Solar Boy Django) (Bug #46)
BIOS call RegisterRamReset is currently stubbed out (Bug #141)
Audio channel reset flags (Bug #142)

[2] Flash memory size detection does not work in some cases, and may require overrides, which are not yet user configurable. Filing a bug is recommended if such a case is encountered.

[3] 10.7 is only needed for the Qt port. The SDL port is known to work on 10.6, and may work on older.
