ctr_vercheck was originally created by wolfvak - It was initially intended to be a small application for the Nintendo 3DS to check your current FIRM and OS version only. I decided to fork this project, and added additional device info similar to PSPident, hence the name 3DSident.

  • Display initial system version.
  • Model detection with code name and hardware info (Retail/Devboard/Debugger/Capture unit)
