Snes9x 3DS v1.30 is released. Snes9x for 3DS is a high-compatibility SNES emulator for your old 3DS / 2DS. It runs many games at full speed (60 fps). It supports games that use CX4 chip (Megaman X2/X3), and the SDD-1 chip (Star Ocean, Super Street Fighter 2 Alpha). It can also play games that use the SuperFX chip (Yoshi's Island, etc) but they run with plenty of frame skips. It has generally much high compatibility than existing SNES emulators on the old 3DS because it uses Snes9x 1.43 as a base, and is a good alternative if your existing emulators cannot play all the games. Includes source code.

Snes9x 3DS v1.30 changelog:
Improved sound synchronization.
Added BlargSNES DSP Core (experimental) for performance. The original Snes9X DSP core (default) suffers from sound skipping in some games like Aladdin and Gradius 3. You can choose which DSP core to use from the Options menu. The BlargSNES DSP Core sounds similar to the Snes9x Core for most games. Sounds like Final Fantasy 3’s the howling wind sound different.
Added support for Tengai Makyou Zero English Patch (for hopefully all future versions)
