I just tested the latest beta and it's great that the compatibility is improving. I can also confirm that the Strongbad games work, and the Tales of Monkey Island games also work!
Like other users here I also had problems with wiiflow: if I use wiiflow r346 on IOS249, it freezes when I try to play a game that uses another cIOS. It also freezes when downloading new covers.
If I go back to r304, I can play a game that uses another cIOS, but the downloading cover issue remains. I'm not sure if this is a cIOS issue or a wiiflow issue, but I thought it was worth reporting.
