There are ways to see whats been done to the wii but I suggest you just follow the softmod any wii guide linked in my signature. Doing so will ensure that your mod and apps are up to date as well as give you the experience you need to know how to address future changes. Once you follow the guide you will be able to safely download the netflix channel too. As far as slow loading games, perhaps the updated mod will help or it's an hdd issue. I suggest that you just use the original discs until you have remodded.
