RetroArch v0.9.9 Wip3 is released. RetroArch is a multi-system emulator for Linux, Windows, Mac OS X and *BSD. It is formerly known as SSNES. Its design and background is quite different than most other emulators as RetroArch does not implement an emulation core itself. RetroArch talks to libretro, a generic emulator core API. This means that RetroArch is core agnostic, and it does not care which emulator core is running.

Currently there are libretro implementations for systems such as SNES, NES, GBA, GB/GBC, Genesis, and even arcade games (Final Burn Alpha).

libretro isn't only usable for emulators. A preliminary port of an open source reimplementation of Cave Story has been ported to libretro as well.

RetroArch believes in modularity. The application itself is a command-line driven application suitable for HTPC and/or headless use. There also exists a GUI frontend for RetroArch, supporting every single config option available in RetroArch.

The Windows binaries include full build along with redist (~15MB). For later updates, it is highly recommended that you download from the Phoenix Updater (RetroArch -> Update). This will reduce updates to ~1MB instead. These Windows builds also include the RetroArch-Phoenix GUI. Note that you cannot update from the old SSNES to RetroArch via GUI. You might get an error that d3dx9_43.dll is not found. If so, DirectX redist is not installed, and you need to install this from Microsoft's homepages. Alternatively it might work to copy over a d3dx9_43.dll from another PC and place it in same directory as RetroArch.
