I am currently on 3.2U and have considered using one of the 4.0 upgrade tutorials to upgrade my system. Then I started thinking about it and I don't really understand the point. I know you get the ability to load wads from a sd card, but this is not that important because I burn all my classic roms onto a dvd to play through the emulators. I don't really find it too be that big a hassle to uninstall/install wads periodically because of the space limitations. And I really don't play many of the VC titles anyway (except for bit.trip.beat), when I have an ever increasing stock of wii and gamecube titles to play. So are there any other benefits of the 4.0 update? I just don't want to get an update I don't really need, and lose the functionality of the things I really care about or create more problems for myself. Has anyone experienced any problems with 4.0, or am I just paranoid because of all the noobs. "Operation Complete" - gonna go play Excitebots now!
