It's been a while since I used my NTSC Wii + Wiikey, can someone please confirm for me that: 1. The newest downloadable Wii System OS from Nintendo is safe to use with Wiikey and what version that is? 2. The newest firmware for wiikey is safe to use and what version that is? 3. Once the OS + Wiikey firmwares are up to date that it is safe to use NTSC versions SSBB and MK Thanks!
