Heres a updated version of the Snes Emulator for the 3DS from bubble2k16:
Never thought I'd be making such a major change to this emu anymore, but here it is:
v1.30 released:
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)
