DIY Raspberry Pi Console #1 - Concept + Overclocking
У вашего броузера проблема в совместимости с HTML5
Join me on my journey to turn a Raspberry Pi 3 into a retro gaming console that is easy to use, with extra bells and whistles! Expand for links and other information that may be helpful, such as overclocking settings. Skip to 17:40 if you don't want the demo!
Please make sure you have an up-to-date kernel and firmware before making any of these changes, or they probably will not work!

Other tweaks:
You can disable the swapfile (not required at all on the Pi 2 or 3 under any situation with Retropie) and redirect some logs to a small amount of temporary RAM to reduce SD card wear using tools from my pitools repository, which can be found here:

You'll want to clone the repository and install no_swap followed by logs_to_ram. I have tested this with the latest release of Retropie. There are also tools there to disable the built-in wifi and bluetooth adaptors if you are not using them, which might free up some CPU (and definitely frees up some RAM).
