This is maybe allready spoken of here on the forum, i didnt find any topic about it thou. If so maybe admins could merge this post.
I have some problems with RetroArch freezez after some time playing a game. When I exit the game after a few hours the whole raspberry stopped working, ssh and everything.
This day i tried a thing that looks like a solution to my problem and i thought i would share it on the forums.
I added BLANK_TIME= to BLANK_TIME=0 in /etc/kbd/config and also POWERDOWN_TIME= to POWERDOWN_TIME=0 in the same file. I have tested this twice so im not 100% sure it works yet so if someone else could test it aswell it would be awesome.
