I noticed in this thread over at the Whinecube message board that Masken is still working on the emulator, and is getting ready for a new release:

It's been a while. I've been working on WhineCube on and off since the last release, trying to get Bust-A-Move 3000 to work, among other things. A lot of work still needs to be done before it's playable, but much progress has already been made. To illustrate, I have updated the screenshots page.

Now it's time for a new release, but first I need beta testing. So if you feel up to it, drop into #whinecube on Efnet to receive your copy.

You can check out the new screenshots by visiting the Whinecube website. Looks promising, Masken!
