Hi. I have been using the latest version of RetroPie successfully with Atari 5200, 7800, NES, and Mame. Once I copy an Atari 2600 rom to the system and reboot, Emulation Station boots to a blank (White) screen. Tried different roms and only having a single rom in the Atari2600 folder triggers this condition. If I remove the roms, systems boots fine.
