Graphics and animations are working, input working, music working.
For the technical reader, it's using a mix of modified OpenGL + native PVR functions.
The video mode is Paletted 8bits (the best for visuals, and for memory consumption).
Things now are very very optimistic for the Dreamcast port.
If the emulator is to be believed, the frame rate will be the same as on pc, 60 frames/seconds.
The Dreamcast port will be in hires 640*480 and the only real difference with the PC version will be the absence of shadows and building reflections on windows for the Dreamcast, and a slight colour reduction.
Everything else should be the same.
PC version will be the best of course, but playing on the Dreamcast might be better for nostalgia reasons.
I'll be getting a real Dreamcast soon!
