NES.app uses the popular InfoNES emulation core to mimic the 6502 processor in a Nintendo Entertainment System, allowing you to play ROM dumps of games designed for the NES console. ROM dumps are files containing the dumped instruction code from a physical cartridge.

Changes since v0.47:

[nervegas] More improvements to save-state wiring (WIP)
[nervegas] Added “Multitouch State” preference (see README)
