I've not modded a 360, but since you don't really have to dick around with DVD drive custom firmwares and shit, I can only imagine that modding a Wii is easier.Birbo said:So once I do this, do I need to avoid all system updates?
At the very least, avoiding Wii FW updates for the first week or three is a good idea, at least until the update s dissected. For example, the most recent 4.2 update included some... not great elements to it. So a 4.2 "safe updater" was developed that installed all of the 4.2 bits without the unwanted anti-hacking rubbish.
Even on-disc mandatory updates are nearly 100% avoidable via homebrew; so you won't find yourself commonly locked out of the most recent games while the scene catches up. HDDs are definitely the way to go, IMHO.
