hi i'm about to get a jp wii with a d2c chip and was wondering about a few things: 1. do i need any setup or configuration disc when i first start up? 2. is it safe to update the wii's firmware through the internet? (i know wii key can but i'm not sure on this one) 3. is it true that this chip doesn't need to be updated unlike the wii key which is up to 1.9g i believe? 4. do i need to burn wii games using specific settings? or can just burn them like normal with imgburn after applying regionfrii and wii brick blocker? thanks very much for answering my questions.
