histat has released a pre-alpha of his port of X millennium for the Dreamcast, an emulator of the Japanese Sharp X1 computer. The port has sound and already good speed.
Emulator files and source code can be downloaded from here:

Here's a tip if you have insane screen flickering (happend for me mostly with the low-res games): go into the configuration menu, and increase the "skipline revisons" (on the 3rd page). That should fix it and make games like Galaxians actually playable.
For hi-res games (like YS) I found that booting in hi-res mode also gives the best picture.
