Disclaimer: This guide will roughly work on later games such as Yo-kai Watch 3, but not Yo-kai Watch 1 as this guide generates V2 QR Codes - it also wont teach you how to make random color coins as im lazy.

First, navigate over to data/res/qr. You should see 3 files:

  • qr_config.cfg.bin - This is for V1 Codes (YW1 Compatibility). DO NOT USE THIS.
  • qr_config_ko_0.06c.cfg.bin - This is for KOR only QRs. DO NOT USE THIS.
  • qr_config_0.04b.cfg.bin - This is for V2 Codes. This is the file you want to edit.

Once you’ve navigated to the file, open it in CfgBin Editor with the latest mytags. In QR2_INFO_LIST:

  • Click on the tree/top-level QR2_INFO_LIST and increase the number by one.
  • Go to the last entry (QR2_INFO_441 on the latest version of Psychic Specters), right click it and click duplicate.
  • Increase StartTypeDec and EndTypeDec by 1 and change the ItemID to whatever you want :P
  • Finally, lets generate some QRs for distribution: Get the StartTypeDec and convert it to base36 using a website like this.
  • Then Go to QRTool - and type the result under V2 type (Make sure the letters are capitalised!).
  • Then select the amount of QRs to generate and enjoy!
