The following is a prototype of the Nintendo DS firmware. It appears to be much earlier than the one we released a few months back and is missing various settings that can be found within that version. Some other interesting things to note are the misspelling of French in the language select menu as well as bloodtype settings within the OWNER INFORMATION menu.


  • Upon boot a sound file of children shouting “Nintendo!” will play.
  • The Nintendo Game Boy Advance logo will appear on the top screen instead of the DS logo.
  • The menu itself is completely different and list-based instead of the spread out options like retail.
