GoldenEye USA self-hosted runtime, assembled October 30, 2026. EmulatorJS frontend 4.2.3 is reused byte-for-byte from the existing COSOM Super Princess Peach runtime. Its retained COSOM modifications disable the automatic version-check call and remove a remote CDN fallback for missing local cores. The source scripts are concatenated into emulator.min.js; emulator.min.css is a copy of emulator.css. The retained ko-KO locale comma correction is present. No new frontend-code modifications were made here. Frontend upstream: https://github.com/EmulatorJS/EmulatorJS/tree/v4.2.3 https://registry.npmjs.org/@emulatorjs/emulatorjs/-/emulatorjs-4.2.3.tgz Only the Mupen64Plus-Next standard and legacy nonthread cores are included. They are unchanged members of official npm package @emulatorjs/core-mupen64plus_next version 4.2.3. Package integrity was compared to the npm registry's SHA-1 and SHA-512 integrity fields. Core internal build 2.0.2, minimum frontend 4.2.2; build report June 14, 2025. Core package: https://registry.npmjs.org/@emulatorjs/core-mupen64plus_next/-/core-mupen64plus_next-4.2.3.tgz Core source: https://github.com/EmulatorJS/mupen64plus-libretro-nx Build source: https://github.com/EmulatorJS/build RetroArch source: https://github.com/EmulatorJS/RetroArch Licenses: LICENSE.txt (frontend GPL-3.0), MUPEN64PLUS-LICENSE.txt (exact license.txt member from the distributed core, GPL-2.0), and RETROARCH-LICENSE.txt. Copyright and component notices remain in source. Runtime wrapper code, journey/route data and saves UI are separate from this vendor directory. All ROM bytes remain unchanged. Core/frontend preservation does not mean the GoldenEye browser game, native save/reload, cheats or controllers were gameplay-tested: the user explicitly waived those tests.
