Snes9x 3DS v0.80 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 v0.80 changelog:
* Fixed NMI interrupt for specific games such as Cu-On-Pa. This allows Cu-On-Pa to get past the selection screen.
* Fixed ROM size calculation for Wonder Project J (English Patch). The game no longer hangs at the menu.
* Implemented optimized rendering for offset-per-tile modes. This gives many games a major performance boost. Games such as Strike Gunner STG, Tetris Attack, Kirby's Avalanche, Contra's Stage 1 Boss, Super Mario All-Stars' Super Mario 2 all benefit from this improvement.
* Implemented optimized rendering for sprites for modest performance boost.
* Used SPC700 core from Snes9x v1.51.
* Re-implemented an moderately optimized SA-1 core. Now games like Kirby Super Star, Super Mario RPG can boot. It will NOT run well on the old 3DS currently, but it will run smooth on a new 3DS with full clock speed.
