Lol, of course it violates, unless of course your have SEGA's written permission to use their Copyrighted property?
Heh. Everything's legal as long as you don't get caught, they say. Seriously, though, I don't think it'll be very wrong to code for Dreamcast now that it's no longer supported.
...No longer supported? ...Don't they still officially Dev new games in Japan and the like, I thought they did?
Yeah, actually. It's all but dead, though. - but yeah, you are right. I should have said "almost" no longer supported, or something similar.... right?
