Nintendulator v0.965 (2009/03/16) 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 v0.965 (2009/03/16) changelog：
Fixed a rather glaring bug (pointed out by a user) which caused read/write breakpoints to not trigger on unindexed accesses (e.g. LDA $2002 or STA $4015) and another bug which caused all instructions not reading from memory to trip breakpoints specified on address $0000.
