title: BIOS/Firmware Dumping
description: How to extract the Nintendo DS or DSi BIOS/Firmware from your console
tabs:
- tab-dsi-sd-card: DSi with Unlaunch
tab-flashcard: Flashcard
---
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.
