DSFetch v1.0.0 — a fastfetch-style system information tool for the Nintendo DS & DSi.
An ASCII DS Lite / DSi clamshell logo on the top screen, with a column of real system info on the bottom screen: hardware model, running mode, ARM9/ARM7 clocks, RAM, language, favorite color, birthday, battery, RTC, SD-card storage, MAC address, and — in DSi mode — region and serial number. Anything that can't be read on the hardware is simply omitted.
Install
Copy DSFetch.nds anywhere on your SD card except the /_nds/ folder (e.g. a roms/nds/ folder) and launch it from TWiLight Menu++ or any DS homebrew launcher.
Built with libnds / devkitPro.
