RustBoyAdvance-NG vs VisualBoyAdvance-M

RustBoyAdvance-NG is a free Nintendo Game Boy Advance emulator and debugger written in Rust. Its WebAssembly demo accepts ROM files by drag and drop, while the desktop emulator loads ROM files or ZIP archives containing .gba files. Desktop use requires a GBA BIOS binary; the project says an open-source BIOS is supported. The repository lists SDL2 and minifb desktop frontends, with minifb marked as unmaintained, plus Java JNI bindings and a terminal frontend. A proof-of-concept Android application can be opened in Android Studio and requires Rust Android targets with the NDK. The custom debugger and experimental GDB server are gated behind build features. Desktop key commands include saving and loading snapshot files, but controls cannot currently be reconfigured. Desktop builds require Rust 1.51 or later and SDL2 dependencies on Linux and macOS. The project identifies CGB audio, including four wave-generator channels, as remaining emulation work. It is distributed under the MIT License and lists Linux, macOS, Windows, web, and Android platforms.

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.
