VBA is a GBA emulator written in C. VBA is an open source project, licensed under the GPL 2.0 (or later). Anyone is welcome to contribute their improvements to the code.

VBA has a strong emphasis on keeping the code as simple as possible, but no simpler. That is, no abstractions, not lots of whitespace fluff but reasonably tight and flexible (where appropriate only!).

VBA has few dependencies: basically GLib and libarchive. This is intended and should remain this way. Frontends can be added and come up with more dependencies to make the user experience richer.

Pick from the list of tasks below, go look at the open issues on GitHub, or just implement whatever missing feature you feel like. If you send a couple of good pull requests, you'll be added as a contributor and get your own commit access.

• Clean up core code, converting it to clean C modules.
• Port fixes from VBA-M and libretro.
• Make use of the game database to provide rich features.
• Port to SDL2
• Add more features to the SDL frontend
• Add more frontends
• Port to more platforms

VBA currently uses CMake for its build system. In order to build for most systems, create a build directory and run:

cmake path/to/vba
make
