[dependabot]

Bumps jsnes from 1.2.1 to 2.0.0.

Release notes

Sourced from jsnes's releases.

2.0.0

Highlights

JSNES 2.0 is a major release focused on hardware accuracy, ease of use, and performance. The emulator now passes significantly more tests from the AccuracyCoin and nestest test suites, supports more games through six new mappers, adds Game Genie cheat code support, and ships a batteries-included Browser class for embedding in web pages with a single function call.

New: jsnes.Browser class

A new high-level Browser class makes it easy to embed JSNES in a web page without wiring up canvas rendering, audio, or input handling yourself:

<div id="nes" style="width: 512px; height: 480px"></div>
<script src="https://unpkg.com/jsnes/dist/jsnes.min.js"></script>
<script>
  var browser = new jsnes.Browser({
    container: document.getElementById("nes"),
  });
  jsnes.Browser.loadROMFromURL("my-rom.nes", function (err, data) {
    browser.loadROM(data);
  });
</script>

The Browser class handles:

• Canvas rendering and scaling to fit its container
• Audio output via AudioWorklet (see below)
• Keyboard input with configurable key bindings (persisted to localStorage)
• Gamepad input with configurable button mapping
• Zapper (light gun) support via mouse
• Frame timing at 60 fps
• Error handling via onError callback
• Screenshots via browser.screenshot()
• Full cleanup via browser.destroy()

It also works well with React and other frameworks — see the README for examples.

Game Genie support

New nes.addGameGenieCode(code) and nes.removeGameGenieCode(code) methods let users apply Game Genie cheat codes at runtime. Standard 6-letter (compare-free) and 8-letter (compare) codes are both supported.

New mappers

Six new cartridge mappers expand game compatibility:

• Mapper 9 (MMC2) — Mike Tyson's Punch-Out!!, Punch-Out!! (PAL). Tile-triggered CHR bank switching via latches.
• Mapper 71 (Camerica/Codemasters) — Fire Hawk, Micro Machines, Bee 52, MiG 29. UxROM variant with optional single-screen mirroring.
• Mapper 79 (NINA-03/NINA-06) — Tiles of Fate, Krazy Kreatures, Impossible Mission II. GxROM-like with register in expansion area.
• Mapper 118 (TxSROM) — Armadillo, Pro Sport Hockey, Goal! Two. MMC3 variant with CHR-controlled nametable mirroring.
• Mapper 119 (TQROM) — Pin-Bot, High Speed. MMC3 variant supporting simultaneous CHR ROM and CHR RAM.
• Mapper 240 — Sheng Huo Lie Zhuan, Jing Ke Xin Zhuan. Simple PRG/CHR banking via writes to $4020-$40FF.
