For Sale:  One (1) loaded 1 TB micro SD card for your Anbernic RG552 handheld retro game system & ALSO includes one (1) 32 GB card for the TF1 slot (they work together and sold in pairs).  Plug them both in to your RG552 and start gaming - uses Linux side of device, not Android side!  These are plug n play.  I took the latest "Amber Elec" (Panda Conspiracy v.2023-02-03) for the RG552  which works great, added my superior game libraries (including some new ones) with full menu art, added 114 ports using PortMaster, plus 8 doom ports, added 18 awesome themes, custom collections, I optimized certain systems for this firmware, optimized card cluster size so small files don't take up too much space, setup custom megadrive-msu system, setup custom bezels for all… I turned it in to the very best card set for the RG552 of its size (for Linux side of device).  AmberElec has a built in online updater using WIFI so you should be able to easily update from the system in the future if you desire.  Includes Saturn, 3DO, NDS, Sega Naomi, Sammy Atomiswave, Playstation, PSP, Arcade (FBNeo/MAME-2003plus), Dreamcast, Sega CD, SNES-MSU1, Megadrive-MSU, 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 (nice benefit of RG552).
18 awesome themes pre-installed.  Also I fixed many features of the themes to have proper artwork, etc.
The preloaded themes include:  Epic-MaxSzalik_Supreme,  EpicMax-Cody_Supreme,  EpicMaxFossil_Custom,  Elephant-Mosquito, Albedo_fixed,  Minimal_Custom,  Supersweet_Supreme,    zSR themes:  Cyber-City, Mario, Metroid, Morrigan, Morrigan2, Piranha-Plant, Rogue, Ryu, Sonic, Tifa & Tifa2,
 
Approximately 40,000+ games including their game artwork and gamelists in the roms directory are installed. Games have video snap previews, mixart, and wheel (header) art typical. Cheats have been pre-installed available through the retroarch menu for many popular systems.
Below is a detailed listing of what is included with this purchase:   
1 TB Sandisk (class 10) micro SD card loaded and ready to game (for TF2 slot) and ALSO a 32 GB micro SD card for the TF1 slot - for your Anbernic RG552 handheld (Note:  Samsung (EVO Select)) card(s) may be provided instead of the Sandisk brand depending on my stock).  No hardware is included, just the loaded sd cards and a tip sheet.
 
Games have video previews that play too as you scroll down through the game list on each system except some of the older computer based systems.  Awesome menu background themes loaded which can be easily switched up.  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).  Superior Arcade and Mame set, all with boxart and preview videos.  I setup game-specific bezel (sideart) to be displayed for over 200 of the best "vertical" arcade games (looks much better for games like Donkey Kong or Tron - see photo).
 
I left about 2 GB free space on the larger sd card available for smooth operation.
