The record

What it does: KuroganeNES is a cycle-accurate NES and Famicom Disk System emulator that runs in a self-contained HTML file in a browser.
Setup: Single-player play requires no installer, plugins, build step, or server; users open nes.html and load a ROM.
Emulation: The project says its emulation is modeled on the NES-001 and verified against blargg tests, nestest, and the AccuracyCoin suite across four CPU/PPU clock alignments.
Game support: It supports 561 mappers and uses CRC32 ROM fingerprinting to select mapper, mirroring, timing region, and peripherals for thousands of known games.
Video and audio: Features include NTSC and PAL timing, a composite-video model, and expansion audio for VRC6, VRC7, FDS, MMC5, Namco 163, Sunsoft 5B, and EPSM.
Play features: It includes save states, rewind, fast-forward, local multiplayer, and online multiplayer for two or four players.
Peripherals: Supported peripherals include the Zapper, Power Pad, Family BASIC and Subor keyboards, Oeka Kids tablet, and Famicom microphone.
Other tools: The project includes Game Genie cheats, IPS/BPS/xdelta ROM patching, an NSF music player, a TAS studio, and CPU/PPU debugging tools.
Integrations: Online multiplayer optionally uses a zero-dependency Node.js WebSocket relay; local and single-player use do not need it.
Online requirements: Remote multiplayer requires Node.js, a TLS certificate, and port 8888 reachable through the firewall and router by default.
Compatibility limit: The v2.0 changelog says save states, TAS movies, and netplay sessions from version 1.x are not compatible with v2.0.
License: KuroganeNES is released under the MIT License, while bundled components retain their own licenses.
Maker details: The opened project page identifies the GitHub account dzoberg as the repository owner but does not state a maker name, headquarters, or founding date.
