Quick update - I've pretty much finished the new version, some highlights:
OS updated, still DietPi based
Card Emulator now working properly
Time Hack mode enabled for 16x2 screen mode
Network section overhauled - you can easily switch between hotspot mode and home wifi mode, static and DHCP addressing, totally customisable
Dimm management overhauled - new network scanner function will find your connected dimms and add them for you, dimms are checked for online/offline status before sending a game and if you have multiple dimms set up for different systems it will send to correct one or prompt with a choice if more than one is found
Audit function removed - all roms are now included and standardised to a proper naming convention and are compressed using gzip so everything fits onto a 32GB card
Navigation improved - games now appear in tiles in the main list, videos have been moved back to the game info screen, when returning to the main list it will drop you back to the same location and there is an option for a floating 'return to top' icon
LCD changes - screen is now in portrait rather than landscape to display the interface better
Various look and feel improvements
In final testing now, release should be within the week
