Lakka on Le Potato stuck on flower boot screen

I own a raspberry pi with Retropie and I wanted to do something along those lines for my son. Raspberry Pi prices are through the roof so I found Le Potato. I flash my microSD and when I insert it into the board it runs, I get the LEDs but when it resizes and then restarts it gets stuck at the flower boot screen. What am I missing, where do I start?

Please read the bold part of the Lakka download page.
