For the Nintendo DSi, the BIOS contains the firmware necessary for the console to function, controlling everything from the user interface to the hardware interfaces.
Many users look for pre-packaged "DSi BIOS Packs." When searching for these downloads, ensure the file sizes match the industry standards: bios7.bin: 16 KB bios9.bin: 4 KB
While basic BIOS dumping covers fundamental emulation needs, a full NAND dump opens the door to the complete DSi experience. The NAND contains everything from the system menu and settings to pre-installed software like the DSi Sound application and web browser.
A standard Nintendo DS emulator might run without BIOS files (using "high-level emulation" or HLE), but the DSi is different. It requires three distinct files:
