Nintendulator 0.975 beta (2015/05/10) is released. Nintendulator is an open source Win32 NES emulator written in C (plus some assembly optimization). The original goal was to emulate the NES down to its hardware quirks; though it's fallen behind over the years, recent builds have caught up once again and can emulate certain behaviors 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 the SRAM folder), 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.

Nintendulator 0.975 beta (2015/05/10) Changelog:
A truly ancient bug related to POV hat configuration and usage has finally been fixed - now, the axis/discrete toggle only affects configuration, and both modes will actually work during gameplay.

The checkbox in Controller Configuration has also been reversed, so that Axis mode (which tends to be more useful for NES controllers) is used by default.
