Nandbin Melonds Top -
To set up your DSi NAND on melonDS, you need to ensure your files are properly named and located so the emulator can boot the DSi system menu and play DSiWare. Required Files for DSi Mode
Vertical Alignment: Mimics the original handheld. Great for portrait monitors. Horizontal (Side-by-Side): The standard for desktop play. nandbin melonds top
Setting Up NAND on melonDS
For a long time, melonDS relied on separate bios7.bin, bios9.bin, and firmware.bin files for standard DS emulation. However, with the advancement of DSi support, the workflow has evolved. To set up your DSi NAND on melonDS,
NAND Flash Memory Bins
: It is the primary method for playing DSi-exclusive digital titles on an emulator. Boot the System Menu Cause: Missing or corrupt firmware
For melonDS to boot in DSi mode, it requires specific system files. While recent versions can simulate basic DS firmware, DSi mode still requires official dumps. Required Files: bios7.bin and bios9.bin (64KB each) firmware.bin (128KB) nand.bin (approx. 240MB)
- Cause: Missing or corrupt
firmware.bin. - Fix: Re-dump your firmware from a DSi. The Old DS firmware (512KB) is often too small. The "Top" requires a 2MB or 8MB DSi firmware dump.
| Problem | NandBin's Fix |
| :--- | :--- |
| "The save data is corrupted" (Pokémon) | Use Export Backup Memory, then Import after converting to 512KB. |
| White screen on boot | Re-dump firmware.bin. It must be exactly 256KB. |
| No microphone input | Use a virtual audio cable. melonDS cannot use real mic on Windows 11 without WASAPI loopback enabled. |
| Slowdown in 3D games (e.g., Metroid Prime Hunters) | Switch from OpenGL to Vulkan. Lower resolution to 2x native, but keep CPU overclock at 133MHz. |
