3DSident is a tool inspired by PSPident, which was originally developed by Jas0nuk and later updated by Yoti. The tool was used to obtain more information about your PSP's motherboard, firmware etc.

Similarly the 3DS version 3DSident aims to display more information about your 3DS. 3DSident is a fork of ctr_vercheck which was originally developed by Wolfvak, and was initially intended to be a small application only used to display FIRM info.​
