Hello Jean-Marie,
After selecting English as the language, I am asked to enter my name (David).
I then press the menu button. This brings up the screen in the photo.
You can see that the name is not displaying as readable below GAMEBUINO. Also the writing below the four icons is not readable.
Pressing the menu button takes me back to to “What’s your name?” screen.
I have reformed the SD card and reloaded the games from both my Mac and Windows computers. The games all show up on the directory of the SD card.
