RockNES v5.6 is released. RockNES is a Nintendo (NES) emulator that supports total PPU emulation, total intelligent emulation (including VRCVI intelligent, used by some Japanese games), battery backed RAM, Famicom DiskSystem, VS Unisystem, and some 70 different mappers. In gain, RockNES includes lots of different video modes, as substantially as the ability to loading and economise your back at any stage. You can flush record movies of gameplay.
