Hello. I'm using 4.0 updated through wanankoko, cios 13 not 13b newest rev. i can play a game, but when i reboot the loader and try to play another game i can't. I first have to unplug to power off, the power button doesn't work, then i can restart the loader and play another game. This happens every time. i installed rev 501, same thing. I then tried rev 478, after reloading get stuck on the game selection screen but can move pointer. Is there a way to work around this so i don't have to power off to play another games.
