neo3DSfetch is a tool similar to the popular "neofetch" but designed for the Nintendo 3DS (of course, you need homebrew/CFW to run it). It displays the current time, a cute ascii art and system information. My inspiration for this was 3dsfetch by videah (from which I also took the ascii art).
To put it simple, it's not as cool as common fetch tools: it does not take the information directly from the system or something.
There's a .ini file it reads information from.
Copy in your SD's /3ds folder the .3dsx file and the info.ini file you find in /source.
To edit the displayed info, edit the info.ini file; here is the order in which you have to write the info (every single piece of info must go on a new line):
