Item description:

This incredible NES emulator lived up to its name upon its very first release. It was written in C++ and it is perfect for games requiring precise timing (like Marble Madness). With support for an incredible amount of mappers, it outdoes some of the best NES emulators around. It also supports NSFs, the famicom disk system, save states, IPS patching, battery-saved ram, NES movie files, and many VS-Unisystem games. Finally, it emulates four non-standard controllers (including the Power Pad).
