I've read through a lot of the guides and they confuse me a little. So I have a few questions that I hope someone will answer. 1. What exactly is RedNAND? 2.Can I use game discs after hacking? 3.If I can use game discs can I go online ? I know with loadline I cant. I ask because my boyfriend loves Smash bros and playing online So if I cant then I will try to buy the disc for him. 4.And um...I have an HDD but I read it has to be format and then it cant work with a computer after that so how do I add more games after that? Or if its not possible then is an SD Card better? Im sorry for any trouble I cause.
