I'm still a bit confused with all the talk of the NAND, so sysnand is basically the devices actual firmware? That you don't touch if its at 4.5 already. Emunand is the spoofed firmware version? And within that, you have normal and classic mode. Classic mode allows you to use retail carts. So why would you ever use normal? And if you are planning on playing roms only and never touching retail carts, which mode should you use? Phew, loaded question.
