Loading LoadingMelonDS cannot decrypt the NAND because the BIOS files provided do not match the specific console keys used to lock that exact nand.bin .
To run full console simulations under DSi Mode, you need a matching matrix of five distinct firmware files extracted from the exact same hardware console: Required File Target File Size ARM9 Processor System Code (DSi specific) 64 KB bios7.bin ARM7 Processor System Code (DSi specific) 64 KB firmware.bin General DSi System Firmware Image 128 KB nand.bin Internal Flash Storage / Virtual Hard Drive approx. 240 MB dsi_sd_card.bin (Optional) Virtual external SD Card storage file User-defined size
Congratulations! You have just created a perfect, legally-sourced copy of your DSi's NAND, ready to be used in melonDS. nand.bin melonds
In the context of the Nintendo DSi, the is the console’s internal flash memory. It stores the system's operating software (firmware), system settings, and any installed DSiWare games.
Because nand.bin acts exactly like a real hard drive, it can run out of space or become corrupted. You can manage or modify the contents of this file using external PC tools. Installing DSiWare via Tools MelonDS cannot decrypt the NAND because the BIOS
This will open a new window displaying all the titles currently installed on your virtual NAND. From here, you can:
To help you get the best performance, could you tell me if you are trying to run or DSiWare titles ? I can also provide a guide on how to use hiyaCFW with melonDS if you want a more customized menu! You have just created a perfect, legally-sourced copy
: Ensure you have a nand.bin file. If you're creating one, follow a reliable guide to dump it from your DS. If downloading, be aware of the legal and safety considerations.

If you have custom firmware, launch GodMode9i via your DSi bootloader or Twilight Menu++.
