BIOS/Firmware Dumping

Some emulators, such as melonDS, require the DS-mode or DSi-mode BIOS and firmware, which are available by extracting from your console. There are two distinct ways to achieve this, using:

  • a DSi with Unlaunch, OR
  • a DS/DS Lite/3DS or a DSi without Unlaunch, along with a flashcard compatible with the console

The DSi method will extract both the DS-mode and DSi-mode BIOS and firmware files. The flashcard method will only extract the DS-mode files.

This page assumes you are running a modern CFW environment from dsi.cfw.guide.
