It seems this might be an emulationstation issue, not retropie.
The FAQ on the ES page said that if ther are white backgrounds for some of the systems, it would indicate an out of memory condition. I have 4 systesm that show white background.
Right now, Sega Genesis, Playstation, and snes show white backgrounds.
It’s not memory though:
total used free shared buffers cached
Mem: 247 96 150 0 15 48
-/+ buffers/cache: 33 213
Swap: 99 0 99
And the weird thing is that ES takes up 20% CPU, but when I open the menu which is blank, it shoots up to 50%.
If I set the memory split to less tha n256, ES doesn’t start up. If i set it to more than 256, it starts, but it’s just a blank screen.
