Does anyone know if ChitChat or Charla still work in terms of connecting to yahoo chat rooms?

"ChitChat Lite is a client for Yahoo Chat, coded in REALbasic for MacOS X.

ChitChat is a stand-alone Yahoo! chat client. It enables the user to "chat" with other users over the Yahoo chat system."

I'm waiting for my macbook replacement and wondering if anyone knows if these programs still work now that there isn't Java chat anymore for yahoo..?
