It's like this. If your a programmer who wants to be able to legally have the right to sell what you've worked on then you wouldn't dare use the Sega SDK since Sega will no longer license anything created with or on it. If your not going to take any money for your project, and your willing to take the chance of potentially having Sega take legal action against you then by all means feel free to go for it with the knowledge that by doing so you are accepting the risk. Most people currently working on projects within the DC dev scene are, like Red Spot Games, hoping to sell their creations for a profit. So for these programmer/developers it would be unacceptable to blatantly attempt to profit from illegally using a coding platform without official approval to do so. And sadly, Sega isn't interested in issuing licensing approvals to homebrew developers so that they can legally make games for a system that is no longer officially supported. In the afformentioned case of the infamous Utopia Boot Loader disc. The person(s) who used a Sega SDK to create this stupid program made it for the purpose of booting up illegally copied (aka bootleg) Dreamcast games. It's seriously questionable in my mind as to wether Sega would have invoked legal actions against this person(s) had they made something more trivial with their talents, such as a a simple import boot loader that would only load legit GD-ROM discs. We'll probably never know the answer to that though.
