Whenever i play my GBA emulator for more than i'd say 20 min, the home and power buttons stop working. Like when you push the home button nothing happens, and when you push the power button at the top nothing happens. Even holding down the power button to soft shut down the ipod doesn't show up. i end up hard rebooting the device and then it works. can someone shed some light on this, and how to fix it? Thanks in advance.
