Everyone knows that the best Sega Dreamcast emulator is nullDC. Unfortunately so far we can not say the same thing about LXDream. But in May 2010 nullDC sources were discovered.
My suggestion is this: programmers LXDream team could use these sources to improve the quality of emulation SegaDC LXDream and bring a new level, making it a truly "one of the best."
Sources nullDC available here:

nkeynes, is the NullDC source code actually of any use to you? I know NullDC was and still is a Windows only DC emulator - but there must be something useful there? Or is it all code that can't be helpful for lxdream in any way, shape or form because it relies on things in the underlying Windows architecture?

I don't know much about anything so sorry if this is a retarded question, but I'd appreciate an answer.

Possibly not as much as you might think. The code is structured differently enough that one can't generally just copy stuff across, and the hardware is actually fairly well understood at this point anyway. What still needs to be done in lxdream is mostly just optimization and filling in a few remaining holes. Oh and rewriting the audio system, but the MAME has had that part available for quite some time as well.

Cheers,
