The answer lies in the difference between high-level emulation (HLE) and low-level emulation (LLE) , and the evolution of DS homebrew.

In short: nand.bin is not a crack, patch, or hack. It is a legally required piece of data that melonDS uses exactly as the real hardware would. Crucially, the original Nintendo DS and DS Lite

For users looking to play Nintendo DS games on their PC, MelonDS is a solid choice. Its accuracy and features make it one of the better DS emulators available.
