About

Nintendulator is an open source Win32 NES emulator written in C++. The original goal was to emulate the NES down to its hardware quirks, and while it's not 100% perfect, it does emulate a variety of special cases that most other emulators neglect to handle. However, this emulation precision comes at a price - a 1500MHz (estimated) or faster CPU is required to emulate at full speed.

Supported file formats include .NES, UNIF, FDS (fwNES format), and NSF. Mappers are handled using external DLLs, complete with extra sound channels for most games which provide them. Other notable features include writing to FDS images (by storing the differences in separate files), authentic Game Genie support (limited to 3 codes), customizeable controllers (including 4 player), input movie recording and playback (with re-recording), AVI capturing, and a debugger with simple breakpoint support. Savestates and battery-backed RAM are saved within the current user's Application Data folder, allowing Nintendulator to function properly when not run as an Administrator.

December 11, 2004

In an attempt to get rid of annoying bugs which caused movies to desynchronize, Nintendulator is now multithreaded. This means that opening menus and moving windows around will no longer cause emulation to pause. Best of all, the change was successful in fixing the aforementioned movie bugs!

Just posting an update on Nintendulator 0.950 development.

Frameskipping code has been vastly improved, and audio data is properly saved in savestates now. Also, slowdown and frame-advance options have been added, allowing users to record movies with extreme precision. Unless some major bugs or feature requests come up, I should be ready to officially release soon.
