If you were to dump your own system files, you would typically end up with several specific components, often requiring specific naming conventions for emulators to recognize them. The only safe, ethical, and reliable method is
To use Nintendo DSi emulation effectively, you generally need specific system files that the emulator uses to mimic the original hardware.
