Great News!!!  ...the "XU10" stock firmware has been cracked and it's a lot better experience now as AmberElec OS features now available!!!!
 
For Sale: One (1) loaded 256 GB micro SD card for your "XU10" handheld retro game system (see pics).  Plug the card in to the TF1 slot and start gaming. These are plug n play. I took the stock XU10 firmware which is very limiting and unleashed much of the underlying AmberElec features. Regular gamelist.xml in each rom folder now working for menu art like video previews of all games, mixart (not that db style that could not be altered).  RetroArch menu available, so optimizations performed, cheats available, custom overlays for vertical games, etc...
 
I added my superior game libraries with full menu art, added custom bezels for over 200 of the best VERTICAL Arcade games, added awesome port games, added 18 themes, tons of custom collections, added missing bios files, background music (can be turned off or switched out easily), I optimized certain systems , I added overlays for Vectrex… I turned it in to the very best card set for the XU10 model. Includes Sega Saturn, Playstation, PSP, premium PORTS, Arcade (FBNeo/MAME-2003plus), SNES-MSU1 i.e. SNES-CD, among many others as listed in detail below.
 
NOTE: The games partition (on larger card) is accessible directly in Windows on a PC for super easy game file transfers/mods/copying/pasting.
18 awesome themes pre-installed.
All themes were fixed to properly display all systems. Some of the themes I added include: Epic Szalik, Epic-Fossil, SagaBox, Elephant-Mosquito, Albedo, Art-Book-Next, Minimal-fixed (with lots of custom added selectable backgrounds), zSR-Cyber-City, zSR-Mario, zSR-Metroid,   zSR-Morrigan 1&2,  zSR-PiranaPlant, zSR-Ryu, zSR-Sonic, zSR-Tifa & zSR-Tifa2.
 
Approximately 16,000+ quality games including their game artwork and gamelists in the roms directory are installed. Games have video snap previews, and boxart/mixart typical. Cheats are pre-installed available through the retroarch menu for many popular systems.
 
Below is a detailed listing of what is included with this purchase:
256 GB Samsung micro SD card loaded and ready to game (for TF1 slot) for your "XU10" handheld (Note: Sandisk card may be provided instead of the Samsung brand depending on my stock). No hardware is included, just the loaded (plug-n-play) sd card.
 
Games have video previews that play too as you scroll down through the game list on each system. Awesome menu background themes loaded which can be easily switched up. Most games allow saving game play at ANY spot within the game typical. Games can be identified as "Favorites" simply. Awesome "Custom Collections" are already setup and can be modified. The Arcade Favorites collections have hundreds of the best arcade games (from the thousand+ on system). Vectrex has awesome transparent overlays that I added which are missing on most systems.
 
 
I left about 1 GB free space on the sd card available for smooth operation.
