I want to ask a question, my Wii U comes with E 1.0.1 sytem menu and since i have been absent from scene i want to know if there is a benefit not to update for a present or future softmod, or to update is essential?
In the last months i had read that loading takes a lot of time and an update came to fix that.
Thanks in advance
Sorry for such a late response but here's your answer.
No, there is no benefit to keeping a low system menu. Any exploits for the vWii remain even on the newest system menu and any Wii U mode hacks remain unreleased (assuming there are any at all). So you're safe to update and I would recommend doing so :)
If I spelled something wrong, I'll just blame it on auto-correct :D
