@ceralor - The nice thing about working at NOA was all the information I had on homebrew over the years. Made it SUPER easy to hack my Wii, Wii U, DSi and 3DSs. :)
@Devourer_ITA @ceralor - We know a lot more than we say, mainly because we don't want to tip off people on how to play our repair system.
When the Wii was still repairable, we knew several ways to check if homebrew was on the system (mostly holding reset on start). If we saw PriiLoader pop up, we knew it had homebrew. But we wouldn't TELL the person on the phone that, because then, they'd know to remove Priiloader before calling to get the system repaired (we refused to repair homebrewed systems and banned the systems). Also - 32004 errors were ALWAYS Homebrew.
As to what we thought of it? Well, that depended on each rep. Personally, I understood WHY Nintendo was so very anti Homebrew...but I knew there were legit reasons to use it. But I worked at NOA, so I had to tow the line when we got those calls
Personally, I don't install Homebrew on my systems until NOA no longer repairs them. I don't want to pirate, I just want a working system. Once NOA stops repairing them, Homebrew allows me to "protect my investment" if my system goes bust.
