Locate the specific .xdelta patch file targeted for your game's region (USA, Europe, or Japan).
If you see a "DSi binaries are missing" error in , your ROM is likely a standard DS-only dump or has been corrupted by a tool like a randomizer that stripped out the DSi-specific data.
This article is the definitive guide to understanding, applying, and troubleshooting the DSi binaries fix for Pokémon Black 2.
Users playing on original hardware generally required a "pre-patched" ROM where the DSi binaries were stripped or the ARM9 binary was patched with AP fix codes. This forced the game to load in "DS Mode" exclusively, ignoring the complex DSi boot sequence that flashcarts could not handle.

This happens if you try to force DSi mode on a ROM where the DSi binaries were completely deleted by an old patching tool. You must delete that specific ROM, acquire a completely clean version, and patch it using the xDelta method detailed above to keep the binaries intact. Save File Won't Transfer Locate the specific

Early fixes involved manually opening the ROM in a hex editor, locating the specific offsets responsible for the anti-piracy loops, and replacing those instructions with "NOP" (No Operation) null values. This tricked the game into believing it had passed the security check. 2. DSi Mode Decryption Users playing on original hardware generally required a
