Translations:About RGB-Pi and Raspberry Pi4/7/en

• The frontend, which makes use of Pygame SDL1 and surface objects, has been remade from scratch to avoid the performance issues that suffered in Pi4 due to changes in video libraries. Now it is sprite based and it is prepared to be easily migrated to Pygame SDL2. There is a bug in Pygame SDL2 that prevents us from reinit the video while the frontend is running. This issue is currently being addressed by Pygame development team.
• The ALSA audio drivers was changed to make some of the internal virtual devices comply with the standard naming and configuration That resulted in some audio features like EQ and audiojack broken. All issues with ALSA audio have been resolved.
• Raspberry USB PCI hub descriptors and sorting has changed resulting in controller ordering not matching with Retroarch anymore. Also RetroArch changed their sorting engine. After some work on our controller engine, it is now already fully adapted to match all these changes.
