Visual Boy Advance-M is a fork of VisualBoyAdvance with additional improvements. RetroArch's VBA-Next is based off an older revision of VBA-M with added speedhacks and tweaks, making it a bit less accurate in some respects, though it fixes a few games such as Advance Wars 2. Higan's GBA core is cycle-accurate, but is otherwise very much a WIP and not as compatible as either version of VBA.
The last official release of gpSP was version 0.9 by Exophase. There are, however, two superior forks: gpSPmod and gpSP-J. gpSP-J has superior compatibility, while gpSPmod has more options for customization (full screen, cheats, etc). Both are superior to Kai.
