Nand.bin — Melonds !!hot!!
In , the nand.bin file is the virtual heart of Nintendo DSi emulation. While standard DS games can run without it using high-level emulation, the nand.bin is essential for booting the DSi home menu, using its system settings, and playing DSiWare titles. Why You Need nand.bin

- Legality & availability – You must dump
nand.binfrom your own DSi (using tools likedumpToolorhardmod). No legitimate pre-made downloads exist; using someone else’s NAND is legally questionable and can cause unique IDs to collide. - Setup complexity – New users often struggle with paths, missing
dsi_nand.binvsnand.binnaming, and the requireddsi_bios9.bin/dsi_bios7.binalongside it. - Feature incompleteness – Wi-Fi and DSi Shop connectivity are still experimental; not all DSi system apps work perfectly.
- Larger resource usage – Emulating NAND access adds overhead compared to DS mode.
Bottom line
- For regular DS games (
.ndsROMs) → No. melonDS works withoutnand.binusing DS firmware (bios7.bin, bios9.bin, firmware.bin). - For DSi games or DSiWare → Yes. You must provide a
nand.binfrom a real DSi console.
