[NES] MyNes x86 7.5.72

Al Hadid opublikował nową wersję emulatora NINTENDO8 - MyNes, gdyby to jeszcze z samo siebie obsługiwało archiwa. Można pobrać wersję natywną dla Windows lub też SDL/GTK - wersje różnią się jedynie GUI - rdzeń jest identyczny (ponoć GTK może być szybsza niż Windowsowska, która w skrajnych przypadkach będzie nas zmuszać dodatkowo do pobrania biblioteki SlimDX).

Guerrilla War (1987, SNK)

My Nes Version 7.5.7100.2949; Built at 10, Jun, 2019 01:38.

  • Added: enable filters in Audio option.
  • Improved: sound playback quality (both renderers) by configuring buffer size and latency (buffer options are removed).

Notes:

  • It is recommended to switch into SlimDX renderers, for both video and sound for this version (unless there are quality issues).
  • My Nes emulation engine outputs sound at ~1.79 MHz, in real nes (as described here <http://wiki.nesdev.com/w/index.php/APU_Mixer>) there are 3 filters:
    • A first-order high-pass filter at 90 Hz
    • Another first-order high-pass filter at 440 Hz
    • A first-order low-pass filter at 14 kHz
  • Now My Nes implement all these filters after output in 1.79 MHz. All filters (low-pass and high-pass) are implemented as described in the wiki, in other words, they work using the actual physical equations.
  • After that, for down-sampling into the playback sound frequency, a low-pass filter is implemented at playback frequency as well.
  • So, in My Nes, the audio process works like this:
    • EMU OUTPUT at ~1.79 MHz => high-pass filter at 90 Hz => high-pass filter at 440 Hz => low-pass filter at 14 kHz => low-pass filter at playback freq (i.e. 44100 Hz for default) => write samples into playback buffer (i.e. play sound).
    • If you notice performance issues in this version or simply you don't like the sound quality, you can still disable this filters in the main menu: Audio>Enable Filters.
  • When this option is disabled, the filters order will be like this:
    • EMU OUTPUT at ~1.79 MHz => low-pass filter at playback freq (i.e. 44100 Hz for default) => write samples into playback buffer (i.e. play sound).
  • This may cause some sound issues like aliasing, corrupted square melodies ...etc
    • Sound buffer size is now fixed for each renderer: 16 KB for SlimDX Direct sound and 5KB for SDL2Sound. These buffer sizes found best for quality and performance.

My Nes Version 7.6.7241.40720 | Core Version 7.6.7241.40719 |Built at 29.10.2019 22:37

  • Added: ability to switch audio mixer (between My Nes internal mixer and nes mixer that described in wiki). Details can be found in new page of the Getting Started dialog.
  • Imporved: FPS limiter, now it is 100% accurate (for all threads).
  • Fixed: DMC DMA and OAM DMA. Now all related tests pass (some games fixed such as Teenage Mutant Ninja Turtles sprite glitches).
  • Fixed: Sprites priority. (Can be noticed in Super Mario Bros 3 when you take the first maschrum)
  • Fixed: ppu timing (no bug, the timing was wrong with a cycle shift, now the timing matches exactly the diagram that provided in nes wiki here: <http://wiki.nesdev.com/w/index.php/File:Ntsc_timing.png>)

  • Fixed: Square sound channels sequencers (wrong counting through the look-up table).
  • Fixed: sound aliasing by implementing proper low-pass filter for down-sampling.
  • Improved: sound quality by adding the proper filters as described in nes wiki.

Byuu wrócił do pracy nad swoim multiemulatorem maszynek NINTENDO i oto efekt - pierwsza wersja publiczna tego najwierniejszego udawacza SUPER NINTENDO. Nowy BsNes jest szybszy, nie wymusza konwersji romów (co miało podnieść czystość dumpów a wniosło sporo niepotrzebnych operacji) więc na 100% warto posiadać i używać. Dodatkowo Byuu wprowadził znany z mutacji ...

Emulicious to nowy, przynajmniej dla mnie, projekt multiemulatora systemów SEGA (master system, game gear) i Nintendo (Gameboy BW/Color) napisany w Javie. Celem emulatora jest dołączenie do aplikacji typu cycle exact, jednak po drodze do tego multiemulatora dodano parę ciekawych narzędzi - podgląd spritów, kafelków i całkiem użyteczny debugger.
