Free ns0 software for windows

Nintendulator is a free, accurate NES emulator written in C that was designed with quality over speed in mind.
The eventual goal of Nintendulator is to be the most accurate NES
emulator, right down to the hardware quirks. In the meanwhile, it can
certainly be used to test NES code with confidence that if it works
properly in Nintendulator, it will probably work properly on the real
hardware as well.
