EmulatorJS vs VisualBoyAdvance-M

EmulatorJS is a free, open-source frontend for RetroArch that lets a site owner embed an emulator in a web page. The project provides a code generator, and says the resulting embed can be added with a few lines of code. EmulatorJS uses RetroArch’s libretro cores to run games. Its supported systems documentation includes NES, Nintendo 64, PlayStation, PSP, Sega systems, and Commodore systems, though the project warns that this list may be out of date. Built-in options allow customization, and multiple languages are supported. The project describes EmulatorJS as a library or plugin rather than a standalone website, and it does not provide a Docker container. A public CDN offers paths labeled stable, latest, and nightly. The listed platforms are web, Android, iOS, and self-hosted. Pages must be served through a web server; opening an HTML file directly is unsupported. Threaded cores may improve performance, but need SharedArrayBuffer enabled through COOP and COEP response headers. The 4.3.0-pre release is marked as a prerelease and is discouraged for production use where stability is needed.

VisualBoyAdvance-M is a free, open-source emulator for Game Boy, Game Boy Color, and Game Boy Advance. Builds are listed for Windows, macOS, Linux, and Android, with Android nightlies for arm, arm64, riscv, and x86_64. The project lists Windows XP and later, macOS, and Linux among desktop requirements; Linux distributions may package it under visualboyadvance-m or vbam. Game Boy and Game Boy Advance linking is enabled by default. Build options also include Vulkan video output, Windows Direct3D support, and FFmpeg audio and video recording. A debugger is enabled by default, and Lua scripting is available for the wxWidgets port. The project provides a Libretro core option and nightly builds for Libretro. Graphics upscaling is supported, but the project cautions that xBRZ and ScaleFX may not run on older or weaker systems. The license is GPL-2.0. For support, the project points users to Discord and suggests trying Help → Factory Reset when issues occur.
