Deunan (a.k.a. dknute) has posted news about Makaron, his Dreamcast emulator.

I knew there was a good reason for not touching the GD-ROM code. But I did, 
and as it stands now it's pretty broken - I will need to redesign it quite a  
bit.
There are several major problems to solve, all tied to multithreading. 
Unfortunately I don't really know how to fix them. Or rather, I do, just 
haven't come up with an idea I feel like implementing. I'd rather spend some 
time thinking about it and do it right (well, mostly) than throw a ton of 
nasty patches in. I might actually have to pull out a drawing block, some 
pencils, and start designing it on paper first. This is a bit new to me, not 
being able to easily cover for all possible cases in my head. I guess that's 
MT for you...

I hope to release something in the first week of April. If the new GD code is 
not ready by then, I'll revert to the old one. I want to see if vibration 
works for other people too. By the way, I haven't done a single thing during 
holidays  I blame Knurek. And Shin Megami Tensei: Lucifer's Call he told me 
about. But mostly Knurek.
