VisualBoyAdvance2 SVN r309 is released. VisualBoyAdvance2 is a free, open source (GPLv3) GBA emulator. It runs on Windows, Linux and Mac, because the front-end is completely written with Qt 4. The code is based on VBA-M, but auther already rewrote many parts of the code. gbxemu was originally a minimal version of VisualBoyAdvance with only the GBA core and the SDL interface. It was more like an experiment.
