Hi GBAtemp. User @shutterbug2000 has found a way to merge two badge datas to essentially give yourself the badges of another player that has made their files publicly available. In this tutorial, we'll be using @Februarysn0w's badges (he/she has collected over 900 badges). Februarysn0w's badge data: https://onedrive.live.com/?cid=b6305612e3c95fbd&id=B6305612E3C95FBD!694&authkey=!ANwz34EVEYjGARc 1. Open the target's BadgeMngFile.dat and yours in a hex editor of your choice. (HxD is preferred) 2. Copy from 0x0 to 0xc (ctrl+g "C"; hex checked) from the target and then pastewrite the strings onto your file. 3. CTRL+G to "3E8" and select everything starting from there to the end of the file and pastewrite it to yours once again. (Alternatively, you can copy from 0x1C to 0x20 from your file and then pastewrite the strings onto the target. Using this method, you can skip step 2 and 3. Then simply copy the target file to your 3DS) 4. Save the edited BadgeMngFile.dat. 5. Copy the modified BadgeMngFile.dat and the target's BadgeData.dat onto your SD card and import them. Please reply to this thread if this worked for you! Great videos by @Ericzander: CFW users: Homebrew users: EDIT: A lot of people don't know what to use. If you're a CFW user, use SaveDataFiler. If you're a *hax user, use ext_data dump tool or Sunshell by Rinnegatamante.
