Some games, particularly later releases or those that utilize DSi-exclusive features, require the specific BIOS and firmware to function without crashing.

The code inside the DSi BIOS and firmware belongs entirely to Nintendo. Distributing or downloading these files constitutes copyright infringement.

Disclaimer: This article is for informational purposes only. You should only use BIOS files dumped from your own console.

Ensure your files are named exactly as required by the emulator (usually lowercase letters: bios7.bin , bios9.bin , firmware.bin ).
