APU:
- Added code to properly emulate race conditions when writing to APU registers at specific times.
- Add noise playback frequencies for PAL emulation.
- Fixed DPCM playback to properly emulate cycle stealing from DMA.
- Rewrote APU frame timer to properly handle clock jitter.

AVI:
- Major cleanup of AVI capture code.
- Optimized AVI code to cache video frame information between frames.

Controllers:
- Rewrote code for all controllers to use proper C++ classes.
- Fix data/movie storage for several controllers to allocate the correct amount of memory.
- Changed Zapper code to determine "hit" based on overall brightness of the target region.
- Added support for Vs. Unisystem Zapper controller.
- Added ability to configure POV hats, either as 2 overlapping axes or as 8 buttons.

Debugger:
Completely rewrote debugger. New features include:
- Edit CPU registers
- Toggle individual IRQ sources
- Browse CPU, PPU, Sprite, and Palette memory
- Add breakpoints based on execution address, operand address (read or write), specific opcodes, or interrupts.
- View detailed properties of nametable entries, sprites, pattern table tiles, and palette entries.

Game Genie:
- Fixed several bugs which could cause entered codes to not work.

Graphics:
- Added support for fullscreen display.
- Added option to add scanlines for 2x Windowed and Fullscreen modes.

- After adjusting palette and saving changes, immediately redraw the screen using the updated colors.
- Add option to preview appearance of palette using various color emphasis modes.

Mapper Interface:
- Updated Mapper Interface version from 3.6 to 3.7.
- Updated ROM Information structure to support iNES 2.0 format fields.

Movies:
- Added a dialog for movie recording, allowing a description to be added (Unicode version only) for the movie being recorded.
- Added a dialog for movie playback, allowing the movie's properties to be previewed before movie playback actually begins.
- Fix problems with playing back movies of games whose mappers maintain state information between resets.

Main Program:
- Savestates, movies, SRAM, and debug memory dumps are now stored within the currently logged in user's Application Data folder rather than within the program's own directory.
- Nintendulator will now attempt to prevent any configured screensaver from activating while emulation is active.
- Builtin iNES header editor now detects and automatically cleans ROM headers bearing the "DiskDude!" signature.
- Fixed several bugs with configuration storage.

PPU:
- Enabled per-cycle emulation of sprite evaluation.
- Improve emulation of PPU I/O registers to properly handle several race conditions.

Savestates:

Mappers:
- Fixed some MMC5 emulation errors.
- Reduced VS Unisystem coin insert delay.
- Fixed several bugs in NSF player BIOS.
- Enabled 8KB PRG RAM on iNES mapper 0.
- Fixed several issues with iNES mappers 22 and 23.
- Added support for iNES mappers 37 and 38.
