Snes9x 3DS v1.00 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 v1.00 changelog:
* Transplanted the full SPC700 + DSP source codes from Snes9x v1.51 into this emulator. As a result, the sound emulation now supports Gaussian Interpolation, and has better accuracy. This fixes some sound problems in Clay Fighter and Mortal Kombat I and II.
* Fixed Mode 7 priorities in games that use this: Contra III's stage 1 (at the loss of some color fidelity). Implementing this required the use of some crazy math hacks and hardware tricks to pull this off.
* Implemented some experimental speed hacks for Super Mario RPG and Kirby's Dreamland. Runs slightly faster (still not full speed) on Old 3DS.
* Implemented hi-res translucency. We get non-flickering emulation of hi-res screens (Secret of Mana, Seiken Densetsu 3, A.S.P. Air Strike Patrol) now as a bonus. As a result, Kirby's Dreamland is now playable.
* Invented a new cheat file format .CHX (text file) so that players can add cheats by using any text editor.
* Centralized the SNES output screen vertically on the top screen.
* Overhauled the user interface to give a more modern look as well as provide additional fonts.
* Added more screen stretch options as requested by many users.
* Added 3D slider support. Pushing up the 3D slider doesn't create any 3D effect, but may create a better viewing experience.
* Removed unnecessary debug messages during start up / shut down of the emulator.
* Fixed a bug when the SRAM still saves randomly when it is set to Disabled.
* Removed memory footprint for storing texture position caches.
* Made this version buildable with libctru v1.2.0 (thanks to Maki-chan) [Note: Building with devkitARM r46 and libctru v1.2.0 will cause a bug where the emulator cannot utilize the full clock speed of the New 3DS.]
