Homebrew Danger from WADs?

[Aquitaine]

Unfortunately, due to school costs, I am selling my Wii.

I've installed the Homebrew channel in the past and used it to install a few VC games. If I delete the Homebrew Channel, TPhack and anything else that indicates hacking/homebrewing is it safe for me to leave the games on there? I'd like to leave them there for the next guy that owns it but I don't want to if he could brick his Wii some how later on if Nintendo releases new firmware and he downloads it. Basically, is there anyway to tell that these games weren't acquired from the Wii Store, and thus are unsafe for me to leave on his machine?

Just leave everything on there and the next guy will get a pleasant surprise out of the HBC. leaving wads on isn't dangerous.

Well I don't want to leave the HBC on there in case he doesn't take to kindly to that kind of thing, he is getting all of my stuff though so he can slap it right back on if he knows about it and wants to. I just wanted to be sure he won't get bricked if later Nintendo releases some firmware updates like 3.3 that mess with the HBC and TP saves. Thanks for the reply.
