It's time to clear out many of my new, duplicate devices I have so here is this gem!  Shipping is included to within USA only (no outside USA orders on this listing please).  Ships from Raleigh, NC USA.
 
For Sale:  Anbernic RG351MP Handheld (Blue color) as pictured.  Includes my 512 GB+32GB card set (AmberElec) as described below:
 
Tons of SNES-MSU (SNES-CD) and Megadrive MSU!  Uses latest AmberElec OS which is best for this device.
 
I took the latest "Amber Elec" (v.2023-02-03) for the RG351MP  which works great, added my superior game libraries with full menu art, added 112 ports using PortMaster, plus 8 doom ports, added 19 awesome themes, custom collections, added missing bios files, I optimized certain systems for this firmware,… I turned it in to the very best card set for the RG351MP.
 
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 RG351MP).
19 awesome themes pre-installed.  Also I fixed many features of the themes to have proper artwork, etc.
The preloaded themes include:  Epic-Szalik, Sagabox, Carbon, Elephant-Mosquito, EpicFossil, Albedo, Art-Book-Next, Minimal-customized (added backgrounds to choose), SR-Cyber-City, SR-Mario, SR-Metroid, SR-Morrigan 1 & 2, SR-Piranha-Plant, SR-Rogue, SR-Ryu, SR-Sonic, and SR-Tifa 1 & 2.
 
Approximately 38,000+ games including their game artwork and gamelists in the roms directory are installed. Games have video snap previews, 3D boxart, 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:   
RG351MP handheld (blue) and 512 GB 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.
 
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 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 removed "ADULT only" roms typical from default setup, but I included them (for 14 different systems) with their artwork in the main roms folder (not visible on device).  So by inserting the 512 GB card into a PC, a simple copy-paste on a pc will put them all in their proper place in the rom system folders to enable/display after reboot.  The "gamelists.xml" files are already setup for them to be added.  Example of these type of games would be mame roms:  newfant.zip, galpanic, bigtwin, plgirls, etc..
 
I left about 1.5 GB free space on the larger sd card available for smooth operation.
