Notes about the GBFS file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The GBFS file type is primarily associated with 'GBFS' by Pin Eight. GBFS is an alternative to the various "incbin" hacks (such as bin2h, b2x, objcopyroda/interflip, etc.) used to put binary data (such as graphics, text, maps, and sounds) into a Game Boy Advance program. Each GBFS archive holds several image, sound, map, or script objects in several freeware apps and games for Game Boy Advance and Nintendo DS. One or more GBFS files may be appended to a compiled program to create a complete ROM.
