I have been following an issue in the GitHub page of Emulation Station that pops up over and over again. People find that after playing NES or SNES or any Libretto backed emulator for over 30 minutes causes them not to be able to get back into Emulation Station. You just end up with a little white dot and no progress is saved that you have made in your half-hour or more of playing. Boo!

Today, Alexander Blohme posted a fix on the ES repository Issues page. It can be found here

Basically, the RPi was going to sleep in the background while you play the emulator, if I understand correctly. Even if I don’t, this will hopefully fix the error permanently. Visit the link for his solution!
