What it does
FCEUX emulates NES, Famicom, Famicom Disk System and Dendy systems. It combines ordinary play with debugging, Lua scripting and tool-assisted recording tools.
Select the timing mode appropriate to the software before analyzing its behavior. The emulator distinguishes NTSC, PAL and hybrid modes, which matters for frame-based work. Its debugging and movie tools make it useful for studying a game’s behavior as well as playing a permitted copy.
