Q: is it at all possible to run old pc/ms dos games on my wii? stuff like Monkey Island 2 etc
A: Yes, it is! I have Sam & Max and Day of the Tentacle on my Wii. You have to first hack into your wii using the "Twilight Hack" (you can search for it on google) then i would recommend installing the "Homebrew Channel" then install the "ScummVM" then find the games. I'm at the stage of finding the games now. There's plenty of videos of people playing games like that on youtube. I'm going to try to email them to find out where the games are. Here's a start for you http://wiibrew.org/wiki/Homebrew_Channel
