Wise fwom your gwave! zombie emu! heres the news straight form the homepage:

'Chris Double of New Zealand has put together a set of patches that seem to fix a lot of bugs and add new functionality to DSemu. He's amalgamated them into a new version, 0.4.0; maybe he has skipped a few major version numbers, but I don't mind. I'm going to try to obtain the source, and flick through to see what the salient modifications are; in the meantime, I'll change the Download link to reflect a new version.'
