I'm sure the question has been asked but why all the trouble to downgrade? Why can't the efforts be put in getting it to work with 2.0 software instead of 1.5.
by "games for 2.0" i take it you mean homebrew for 2.0. Well, im pretty sure devs are attempting this. But 2.0 has updgraded securuty patches. And it quite difficult to crack. So far, theres only 1 homebrew out for 2.0, and its not really homebrew either and its kinda useless. But either way, its 1 step closer to cracking 2.0. Just have patients.
