Anyway, I just do not like calling a major achievment like that a proof of concept thing, even if it basicly might be correct: There's not much that came out of the technique Chui introduced for loading bigger files into the Dreamcast's RAM - except that he got games like Shock Troopers and Blazing Star to work perfectly!
I assume that the next release (initially sheduled for autumn 2006) will allow a lot more games to work as well as these.
