With continued development bringing features like DSP HLE and microphone support, melonDS is rapidly closing the gap between emulation and the real hardware, preserving the DSi library for years to come.
While mainline MelonDS continues to improve its performance gradually (with Vulkan support added in 0.9.4, narrowing the gap), Nandbin’s fork remains a fascinating case study in —a reminder that sometimes, “good enough” is exactly what a specific audience needs. Just don’t expect to finish Elite Beat Agents on it. nandbin melonds
A "NAND bin" refers to a raw backup of the NAND memory from a Nintendo DSi or 3DS console. The NAND contains the system's operating system (firmware), system settings, and installed applications (DSiWare). With continued development bringing features like DSP HLE
Without a valid nand.bin , trying to toggle "DSi Mode" in melonDS will trigger errors such as "could not find DSi NAND" or cause the application to crash completely. How to Acquire a Valid nand.bin A "NAND bin" refers to a raw backup
Emulating the DSi is a fantastic way to preserve a unique era of handheld gaming. With your nand.bin in place, you’re ready to explore everything the DSi has to offer right on your PC or Android device! Howto/FAQ - melonDS
