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.

November 24, 2005

A few major bugs (dealing with recording movies from savestates) have been fixed, and a few new mappers have been added.

After some consideration, I realized that there's no point in including separate downloads for the beta mapper DLLs when the beta emulator binaries always include them.

November 19, 2005

Partial VS Unisystem support has been readded to Nintendulator, in the form of a new mapper DLL - VS.DLL. Mappers 99 and 151 have been removed from iNES.DLL as a result.

Automatic VS palette detection will likely not be implemented, and it'll be a while before the VS palettes are added.

June 30, 2005

Nintendulator has been modified to support Unicode; separate downloads are now available for ANSI (Windows 9x/ME) and Unicode (Windows NT/2K/XP) binaries.

March 14, 2005

After trying for perfection for too long (and never reaching it), I've decided to formally release Nintendulator 0.950.
