The Dsi Binaries Are Missing Please Obtain A Clean Rom

FIXED: "The DSi binaries are missing. Please obtain a clean ROM" (NDS Emulation Guide) If you’re seeing the error message "The DSi binaries are missing. Please obtain a clean ROM" when trying to play a Nintendo DS game on an emulator (especially DeSmuME , melonDS , or a RetroArch core), you’re not alone. This is a common but easily fixable issue. What Does This Error Mean? This error appears when you try to run a DSi-Enhanced or DSi-Exclusive game (a game that takes advantage of the DSi’s extra RAM, camera, or faster CPU) on an emulator that lacks the official DSi firmware files. In simple terms:

A regular DS game runs on "DS mode." A DSi game tries to boot into "DSi mode." Without the copyrighted DSi BIOS/firmware, the emulator doesn’t know how to start the game.

Why Does It Happen?

You downloaded a ROM that requires DSi mode (e.g., Pokémon Black/White , Pokémon Black 2/White 2 , Dragon Quest IX , Mario vs. Donkey Kong: Mini-Land Mayhem ). Your emulator is missing dsi_bios.bin and dsi_firmware.bin (or equivalent). Most emulators do not include these files for legal reasons (copyright).

How to Fix It (Step by Step)

Legal note: You must dump the DSi BIOS/firmware from a console you own. This guide explains the process — we do not provide copyrighted files. The Dsi Binaries Are Missing Please Obtain A Clean Rom

Option 1: Switch the emulator to DS mode (quickest fix) If you don’t need DSi features (most games work fine in DS mode):

melonDS: Config → Emu Settings → Console Mode = Nintendo DS (not DSi)

DeSmuME: Config → Emulation Settings → Slot 0 ND Cartridge → Backup Mode = Auto (and uncheck "Boot into DSi mode") You can use this as a blog post,

RetroArch (melonDS core): Change core option: DS Mode → DS

After switching, restart the ROM. Option 2: Add DSi BIOS/Firmware files (for DSi-exclusive games) You need three files (names may vary by emulator): | File | Typical name | |------|---------------| | DSi BIOS | dsi_bios.bin (or bios7.bin + bios9.bin for DS mode) | | DSi Firmware | dsi_firmware.bin | | DSi NAND | dsi_nand.bin (rarely required) | How to get them (legitimately):
