So. I connected my computer to the gameshell with putty ssh.
I went to the first directory that you give and create a test.sh with “sudo nano test.sh” (basic for the moment)
Inside the test.sh I just type “love” with no other informations.
I launch a game (cavestory) and go back to the menu to reload the start menu…
The screen was freeze to the loading icone…
The thing saved me was the active wifi.
I undo all the things i made and try again to do exactily what you said…
I copy the poweroff.png to rename it foo.png (i used the same name than in your exemple ^^) and create a file Foo.sh in the good directory.
Same action to reload the start screen… And same problem.
But for now the wifi doesn t work.
Now I m downloading the image of the os to burn it on a SD card. I ll try to use a SD card with more space…
Some on can explain to me where is my mistake ? I really don t anderstand.
Thanks for your help
