Medusa alpha 2 is released. Medusa is an emulator for running Nintendo DS, Game Boy Advance and Game Boy games. It aims to be faster and more accurate than many existing Nintendo DS and Game Boy Advance emulators, as well as adding features that other emulators lack. It also supports Game Boy and Game Boy Color games.

Medusa Features:
* Near full Game Boy Advance hardware support[1].
* Partial DS hardware support[1].
* Game Boy/Game Boy Color hardware support.
* Fast emulation for Game Boy and Game Boy Advance. Known to run at full speed even on low end hardware, such as netbooks[2].
* Qt and SDL ports for a heavy-weight and a light-weight frontend.
* Local (same computer) link cable support.
* Save type detection, even for flash memory size[3].
* Support for cartridges with motion sensors and rumble (only usable with game controllers)[2].
* Real-time clock support, even without configuration.
* A built-in GBA BIOS implementation, and ability to load external BIOS files. DS currently requires BIOS and firmware dumps[2].
* Turbo/fast-forward support by holding Tab.
* Rewind by holding Backquote.
* Frameskip, configurable up to 10.
* Screenshot support.
* Cheat code support[2].
* 9 savestate slots. Savestates are also viewable as screenshots[2].

* Configurable emulation rewinding.
* Support for loading and exporting GameShark and Action Replay snapshots.
* Cores available for RetroArch/Libretro and OpenEmu.
* Many, many smaller things.
