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 v0.41:

[nervegas] Restored fast scroll list / bold font – swiping seems better
[nervegas] Fixed compiler warnings
[nervegas] Added notification icons for direction, b, a
[nervegas] Added suspend support (and preference)
[nervegas] Fixed suspend support while running games
