GBA files contain ROM images of Nintendo Game Boy Advance video games. They include exact copies of GBA games to play using emulators. GBA files should not be converted; they are not meant for conversion. Some GBA files use .AGB or .GB extensions instead. These extensions are usually the same format, so try renaming to .GBA. Most files convert with tools, but not GBA. If still unable to open, GBA files need specific emulators like NO$GBA.
Operating systems support GBA files differently. 4 systems handle them. Software depends on the operating system. GBA files have 1509 extensions but most are incompatible. OpenEmu likely generated this particular file. Our tools help work with GBA files: opener, converter, viewer, editor.
Half of GBA files use a common format. They are unreadable binary data, 16-33 MB. The .GBA extension exclusively denotes Nintendo Game Boy Advance ROMs. Games include Zelda, Final Fantasy, Pokemon. GBA files play these games on emulators. They copy ROM chips in cartridges, so are considered backups.
Associate .GBA in Windows Registry to open unknown files. Most contain simple text.
