v0.5.0 Changes:
Additional mappers implemented:
- Namco 108 (iNES mapper 206); used in multiple games including Pac-Mania
and Gauntlet (unlicensed version)
- Namco 108 variant w/ 128KB CHR ROM (iNES mapper 88); used in 3 games
including Dragon Spirit: Aratanaru Densetsu
- Namco 129 / 163 (iNES mapper 19), including Namco 163 expansion audio;
used in multiple games including Digital Devil Story: Megami Tensei II
- Namco 175 / 340 (iNES mapper 210); used in multiple games including
Splatterhouse: Wanpaku Graffiti
- NAMCOT-3425 (iNES mapper 95); used only in Dragon Buster
- NAMCOT-3446 (iNES mapper 76); used only in Digital Devil Story: Megami Tensei
- NAMCOT-3453 (iNES mapper 154); used only in Devil Man
Additional mapper features implemented:
- Konami VRC7's FM synthesizer chip is now implemented; this chip was only
used in Lagrange Point. (The JP version of Tiny Toon Adventures 2 uses
the VRC7 board but doesn't use the audio chip)
- The VRC7 implementation additionally will now work properly with older
ROM dumps that don't specify an NES 2.0 submapper
In the native GUI app, most options can now be changed while a game is running
- Input bindings notably cannot be changed while a game is running, for the
moment
- Renderer (SDL2/wgpu) and wgpu backend also cannot be changed while a game
is running
mplemented fast forward with a configurable speed multiplier
Implemented rewind with a configurable rewind buffer length (10 seconds by
default)
Removed the Adaptive VSync option because it isn't supported on any computer
I was able to test on, including Windows with an Nvidia GPU. Fast VSync
option is still present and is supported on common configurations
Web frontend changes:
- Implemented input reconfiguration instead of having hardcoded key bindings
- Changed the canvas to display random white noise instead of nothing at all
before the first ROM file is loaded
- Reduced the audio sync threshold to hopefully reduce audio lag at >60Hz
refresh rates, although animation is unfortunately still somewhat choppy
at high refresh rates
- Added a button to upload a save file for the currently running game (for
games with persistent save files, e.g. the Zelda games)
- Made some minor tweaks to bring focus back to the emulator after clicking
on certain UI elements, such as the Reset button
- Changed the 'Open ROM file' button text to 'Open NES ROM file'
Fixed a very minor logging bug where the TRACE log message indicating that
an address low byte overflow occurred during an absolute indexed read
instruction was logged unconditionally instead of only logging when overflow
occurred
