Now if you or someone can tell me how to save high scores in mame2016 it will be awesome! I just don't know where the files should go. Original post at: https://retropie.org.uk/forum/topic/23945/high-scores-not-saving-mame2016

I have similar problem. I thought its my adapter to the monitor. I use a dongle for keyboard too. What was the interval when you got this screen freeze? I get it maybe once in a hour. Maybe its a different story on my side.

@mitu Thank you very much! Just needed a good noob starting point, much appreciated.

@mediamogul Worked perfectly, many thanks!
