This error is common when playing DSi-enhanced games (most notably Pokémon Black/White 1 & 2 ) via TWiLight Menu++ or forwarders on a modded DSi or 3DS. What are DSi Binaries?
These are specific portions of a game's code designed for DSi and 3DS systems. They enable "enhanced" features like: Cameras: Used for in-game video chat.
Advanced Wi-Fi: Support for WPA2/modern security settings (DS mode is limited to WEP).
Performance: Slightly faster load times and better battery indicators. Why the Message Appears The second half of the error message is
The error "The DSi binaries are missing. Please obtain a clean ROM" means your ROM file is missing these specific data segments. This usually happens because:
Bad Dumps: The ROM was dumped from a cartridge using older tools (like early GodMode9i) that didn't know how to capture DSi data.
ROM Hacks/Randomizers: Many modification tools "scrub" or destroy DSi binaries because they only focus on standard DS data.
Trimmed ROMs: Files that have had "empty" space removed to save storage often lose their binaries in the process. Solutions and Workarounds The second half of the error message is
You might be tempted to search for a "DSi binaries missing fix patch." Do not waste your time. You cannot add back what was never there. All such "fixes" either convert the game to DS mode (disabling DSi features) or corrupt another part of the ROM. The only real fix is to start over with a clean ROM.
The second half of the error message is written in slightly broken English, but the meaning is crystal clear: "Please obtain a clean ROM. Better."
In ROM hacking and emulation communities, a "clean ROM" or "pure ROM" is an unmodified, 1:1 digital copy of the game cartridge data. It has not been trimmed, patched, cracked, or altered in any way.
Why "better"? The error message is essentially saying the current ROM is inferior (corrupt/missing data). A clean ROM is superior (complete/verified). The second half of the error message is
The emulator cannot locate required DSi console BIOS/firmware files (often dsi_bios9.bin, dsi_bios7.bin, dsi_firmware.bin) or the ROM itself has been modified/trimmed in a way that removes DSi-specific binaries.

Once you have a working setup, follow these best practices to never see "The DSi binaries are missing" again.
