From GameBrew - a wiki dedicated to Video Game Homebrew.


With UsrCheatUp, player can update the cheats database on your flashcard directly from your DS. It requires a full working Wi-Fi Internet connection already setted up on DS.

It was entered into the 2009 best DS homebrew contest.


Supports all files of the gbatemp cheat database:

  • EDGEcheats.DAT
  • user.evoCHEATS


  1. Download and extract file
  2. DLDI patch it and copy it to the root directory of the card

After the first time launching it, UsrCheatUp.nds will create the configuration file UsrCheatUp.ini in the root matching your card type. (If you are updating from an older version you have to delete the old one).
