2019.01.02

The latest beta build of Nintendulator, the Nintendo NES emulator.

– Overall:

- Various code cleanup and bugfixes.

– APU:

- Added separate logic for power-on and soft-reset events.
- Updated various counters to more closely match actual hardware behavior.
- Upgraded audio playback code to use DirectSound 8.0.

– CPU:

- Improved DMA emulation logic to properly handle both Sprite and PCM
operations happening concurrently.
- Removed all inline assembly for 64-bit support.
- Fixed interrupt timing for branch instructions without page crosses.
- Added a configuration setting to suppress Debug statements for
invalid opcodes.
- Added support for undefined opcodes AAC, ASR, ARR, ATX, and AXS.

– Controllers:

- Renamed Alternate Keyboard to Subor Keyboard
- Updated Family Basic and Subor Keyboards to support movie recording
and playback.
- Updated controllers to use Save/Load routines instead of exposing
their internal state as packed byte arrays.
- Updated Arkanoid paddles to support axis configuration and adjusted
range of valid positions.
- Added support for SNES Mouse.
- Fixed support for configuring POV triggers as axes versus buttons.

– Debugger:

- Updated CPU debugger and trace log output to include total elapsed
CPU cycles since reset.
- Improved breakpoint support to properly handle intermediate reads.
- Improved PPU debugger to only redraw pattern tables and sprites when
their corresponding palettes actually changed.

– Graphics:

- Added separate default palettes for each region.
- Improved fullscreen code to attempt to select a resolution which
matches your monitor’s aspect ratio.
- Fix a bug with Zapper emulation while in fullscreen mode.
- Added an alternative Playchoice-10 palette.
- Added a configuration setting for Playchoice-10 palettes to control
whether or not extra gray colors should be added at 1D/2D/3D.
- Fixed color emphasis to swap the Red/Green bits on PAL and Dendy.
- Updated NTSC palette generation.
- Added an option to horizontally stretch the window to produce the
correct aspect ratio.

– iNES Header Editor:

- Moved header editor into its own source file.
- Added support for editing NES 2.0 format fields.

– Mapper Interface:

- Updated Mapper Interface version from 3.7 to 3.9.
- Reordered several enumerated types to be more consistent.
- Added support for debug-safe read handlers which do not trigger side
effects.
- Improved handling of multiple DLLs supporting the same mapper.

– Main Program:

- Updated Winamp plugin to support Unicode.
- Added support for Hybrid (Dendy) timing – PAL’s 50Hz framerate, but
- NTSC’s CPU/PPU clock ratio and VBLANK length.
- Reorganized code for saving and loading configuration settings to be
- localized according to function.
- Increased maximum supported PRG RAM from 64KB to 1024KB.
- Increased maximum supported CHR RAM from 32KB to 256KB.
- Changed FDS disk writing to use a new file format which permits
tracking version numbers.
- Added full NES 2.0 format support.
- Reworked Savestate/Reset commands to avoid stopping and restarting
sound playback (and causing pops).
- Fixed debugger breakpoints to properly unacquire input devices.
- Fixed crash when exiting the program while in fullscreen mode.
- Added a Browse Save Files option to the File menu.

– PPU:

- Removed some unneeded optimizations that didn’t work with 64-bit and
weren’t beneficial with 32-bit anymore.
- Fixed pre-render scanline to reset vertical scroll bits for every
cycle in 280-304 instead of just the last one.
- Removed old non-accurate sprite evaluation logic.
- Fixed emulation of $2007 accesses during rendering and how they
affect the VRAM address.
- Added support for Vs. Unisystem PPUs returning special values from
the lower bits of $2002.

– Savestates:

- Updated savestate logic to better handle version differences.

– Mappers:

- Added support for NES 2.0 custom SRAM sizes
- Added support for various iNES mappers using CHR RAM when no ROM is
present.
- Updated MMC2 emulation for switching the lower CHR ROM bank.
- Updated IRQ counters for MMC3, MMC5, MMC6, VRC4, VRC6, VRC7, and
Tengen RAMBO-1.
- Updated MMC5 sound length counter timing and added support for
read-triggered PCM.
- Updated iNES mappers 1 and 4 to support NES 2.0 PRG RAM sizes.
- Updated iNES mapper 16 to support EEPROM saves, and added mapper 159
as a variant.
- Added iNES mapper 210 as a variant of mapper 19.
- Fixed iNES mappers 21, 22, 23, and 25 to properly reflect their
actual functionality.
- Improved compatibility for iNES mapper 185.
- Added support for NES-AN1ROM, HVC-FKROM, NES-PEEOROM, NES-SC1ROM,
- NES-SHROM, NES-SH1ROM, NES-SIROM, NES-SJROM, NES-SL2ROM,
- NES-SL3ROM, NES-SLRROM, NES-SMROM, NES-TBROM, NES-TEROM,
- NES-TKSROM, NES-TL2ROM, NES-TLSROM, NES-TNROM, NES-TQROM,
and NES-TVROM boards.
- Added support for iNES mappers 28, 31, 36, 48, 57, 72, 77, 82, 92,
