Yea, I agree with a post above mine. The only thing Krikzz could do, is if he finds a way for a flash cart to run games in DSi mode to take advantage of the faster processor and RAM. And afaik, there's only a handful of games that take advantage of that.
I'm not sure if it's even worth it. There's countless DS/DSi flash carts out there. Of course, Krikzz is full of surprises, so who really knows.
