Here’s a write-up for Nandbin’s MelonDS Top—a custom top-screen layout or configuration file for the MelonDS Nintendo DS emulator, often shared by the YouTuber/streamer 낸드빈 (Nandbin).
In the context of the Nintendo DS, the "NAND" refers to the non-volatile memory built into the console. Unlike a game cartridge (which is also NAND memory), the internal NAND stores the Firmware and the DSi Menu (for DSi units).
When we discuss a "NAND bin" in emulation, we are referring to a complete, bit-for-bit copy of this internal storage. nandbin melonds top
Many newcomers fail because they skip the BIOS. melonDS requires three real DS BIOS dumps to achieve full accuracy:
bios7.bin (ARM7 BIOS)bios9.bin (ARM9 BIOS)firmware.bin (DS firmware)The "top" NandBin configuration does not use the built-in "Boot Game Directly" option. Instead, you must: Here’s a write-up for Nandbin’s MelonDS Top —a
Documents/melonDS/bios/.Why? Because many games (like The World Ends With You) rely on DS clock timings that only trigger correctly when booting through the firmware. This reduces crashes by 90%.

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.
