Yes, some nut is trying to port the eninge to the PS3 despite the offical devlopers deaming it impossible to run well and not supporting or helping with it in the slightest. Not only is it already CPU heavy, it is built for x86 based processors, so while it is possible to get it running on a PS3, it will likely run really really poorly.
I do like how Dolphin does pass rendering to the GPU though, while PCSX2 does most of the rendering with the CPU. I also like how Dolphin doesn't need Gamecube Bios, and often has several revisions a day.
I mean, look at what PCSX2 wants from a GPU, and this is a current, upto date version.
