NOTE:  This "Android build" card will require some setup of your stock Retroarch app using the instructions that I include (in other words, not plug n play).  Setup should take about 15 minutes most of which is waiting for certain Retroarch config files to transfer from my card to an internal storage location on the device.  I will answer questions if they arise to help you get it going... this build is worth it!  
 
For Sale: My amazing 512 GB "Android build -fat32" micro sd card (loaded) here for the Anbernic RG552 - TF2 slot (with TF1 card slot empty).   Note:  See my other listing for a similar card for the Anbernic RG552 using the Linux side of the device using 351Elec beta build.  Benefits of this "Android build" are there is really no need to access the linux side of the device and you have quick access to the great standalone emulators for Dreamcast, PSP, N64, NDS, Saturn, Gamecube  & DuckStation (Redream, PPSSPP, M64plusFZ, YabaSanshiro PRO, Dolphin-MMJ & DuckStation, respectively).  Downfalls of the other 351Elec Linux build is that the TF2 card for it is in exfat which cannot be used by the Android side of the device. 
 
Approximately 12,800 games!   Play almost everything from Atari 2600 up through Gamecube, Sega Dreamcast, Sony PSP & Nintendo DS (NDS).  See detailed game counts by system below.
 
What's included: *512 GB micro sd card only (Sandisk or Samsung brand) - loaded with approx. 3 GB free space. Also (not pictured) I will include detailed typed instructions for the initial setup for RetroArch.  I spent many, many weeks building this ultimate "Android build" setup. This card has the games and files you need to setup your RetroArch on your RG552 device. The other standalone emulators can be simply pointed to the appropriate rom folder on my card too, and will run the games from this card.
 
Did your RG552 include the Google Playstore App?  Mine did not yet some seem to.  I can help you with a simple fix to get it added to yours if yours did not.  Customers can ask me for this advice if needed.  It is good to have as certain Android games may require it, and also makes it easier to add Android Apps vs. side-loading APKs.
 
My RetroArch folders on the card (playlists, thumbnails, etc.) allow for an amazing dynamic background theme (background images change for every system as you scroll left/right). Boxart displays for all games in menu. My instructions will explain how to set the paths in your retroarch to the file paths on my card.
 
In RetroArch, games can be identified as "Favorites" simply by selecting "add to faves" in menu just before starting a game. Therefore, you can easily be found in the favorite folder. You can delete games in the "Favorites" system/folder so this list is fully customizeable by you. Awesome "Arcade Collections" are already setup. The arcade collections have hundreds of the best arcade games (from the thousand+ on system).
 
Custom GAME-specific bezels are setup for Arcade and most console and handheld systems. System-specific bezel options are also included and bezels can be easily switched or turned off. They look fantastic though due to the screen so they fill the black space as all games display in native format (no crazy stretching distorting games). That's right, literally thousands of game specific bezels (bezel project) configured specifically for the RG552 screen and installed and enabled (configs loaded per game)… awesome!! See pics for some examples.
 
Cheats are pre-installed for many popular systems, and can be accessed through the retroarch menu in-game. All necessary bios installed on card. All arcade "samples" for proper sound are installed. I have saved certain arcade game remap files so controls work such as Tron (right joystick is dial), Pole Position 1 & 2 (gas pedal mapped), Toobin (all controls remapped to work). For twin stick arcade games this sytem is great!!! Karate Champ, Total Carnage, Smash TV, Robotron... all setup to use both thumbsticks to control! In the RetroArch in-game menu the options and controls can easily be changed and game specific options/remaps saved. The card has a "config folder" and my instructions explain how you transfer these files to the internal retroarch file on your device as Retroarch requires these certain config files be on the internal storage for the overlays to display.
 
Tip:  A few FREE Android games I recommend you get from the Playstore on the device is:  Horizon Chase & Asphalt 8 !  They're great.
