What 44VBA is

44VBA is a free, open-source Game Boy Advance emulator with a WebAssembly version and ports for ESP32-S3 and embedded Linux. The web app at gba.44670.org lets users choose a game file and provides controls for savegame backup and restore, screen filters, mute, turbo mode, and cheat codes. It also offers Dropbox cloud saves with upload and download controls. The site says files are processed locally and are not uploaded to a server. On iOS, it directs users to open the web app in Safari and add it to the Home Screen because of iOS limitations. The repository provides pre-built binaries for Windows and Switch; users can build from source for other platforms. Listed platforms include iOS, Linux, web, and Windows, while the watchOS version is not public yet. The repository lists a GPL-3.0 license. The site cautions against using the software to play games users have not legally obtained. Cheat code controls are available, and the site advises backing up savegames before using them.
