NES-EMU v1.3 is released. NES-EMU is A Nintendo Entertainment System (NES) emulator written in C++. As this is just a pet project, don't expect a full-featured emulator. There is no GUI, many typical features are missing, and only a few mappers have been implemented.

NES-EMU Features:
* Mappers 0,1,2,3,4,7 (~90% of games)
* Accurate audio emulation (no DMC)
* Automatic saving of SRAM
* Save state support
* Rewind any time up to 1 minute at normal speed
* Single and multi frame stepping when paused

NES-EMU v1.3 Changelog:
* Rewind support! Press Backspace at any time to rewind at normal speed up to 1 minute.
* Fixed save states for games that use PRG-RAM that's not battery-backed (like SMB3)
