Asking for people to answer isn't going to get you anywhere. If you are interested in a portable Dreamcast, then it would be better to either commission someone to do it, or do it yourself.
While there is nothing wrong with the Dreamcast and I believe @Shank, @GarageFactory , and @Morgan_The_Adventurer are doing R&D on it, most other users are busy with the contest or are pioneering new things for the Wii.
Getting on a forum and pleading for someone to do something for you is a poor solution to solve your need. If no one answers you, it's because nobody wants to take on the commission or nobody cares to. Either way, there is no need to whine about it. If you aren't satisfied with the state of affairs, get up and do it yourself.
