I agree with Smuko, 1150Mhz seems a lot, At least 930Mhz is running very stable for me, Even Playing psx for more than an hour!

I'm now finished from that forest and also to that airship now I reached to the castle that starts with "L" where the princess sees her uncle. but to be honest this is the first time ever I play Final Fantasy, It's easy to control in the phone! It seems it still running fine! I hope I won't reach anywhere where it will crash again!
