First time installer.

I installed RetroPie 2.3 today. All went well. Got Genesis,SNES, PSX and Atari 2600 games working with a USB gamepad.

While testing the Atari ST emulator I must have messed up and the Pi froze so I unplugged the power.

When the Pi restarted emulationstation is now corrupt.
It still functions. I can use the gamepad to select games and once in the games all works well.
Problem is I have no idea what I’m selecting.
Here is a video I did to show what is happening. The thing in the corner is me showing the gamepad. I was hoping to show me selecting but the contrast to he screen was just to high.

Any tips, advise greatly appreciated.
