VisualBoyAdvance2 SVN r216 is released. gbxemu was originally a minimal version of VisualBoyAdvance with only the GBA core and the SDL interface. It was more like an experiment.

VisualBoyAdvance2 SVN Changelog:
r216
add additional audio synchronization
it might be a good idea to disable the other throttling code in the main window later on
