A new version of the frontend SSNES for the libsnes library has been released. libsnes is the emulator core of bSNES, the most accurate SNES emulator to date, in library form.

Quote:
SSNES 0.9

Changes since 0.9 RC1:

- Allow fullscreen swapping while paused.
- Frame advance/rewind (stepping).
- Allow #include in config files.
- video_base_size for windowed mode calculations.
- Purge libsamplerate support (obsolete).
- Small SSE2 optimizations for sample conversions.
- Audio is heard when rewinding.
- Several bug fixes.

Props to AlexFolland for lots of bug testing and suggestions in #ssnes
