For Sale:  "R36S"Handheld (new transparent ORANGE color) as pictured in my 1st two photos.  Other photos show same cards running on a different colored R36S device.  Includes my ArkOS 512 GB+32GB card set as described below:
 
Shipping is included to within USA only (no outside USA orders on this listing please).  Ships FAST from Raleigh, NC USA - ready to go out the door via USPS Priority mail, about 3 days to deliver anywhere in the USA!  
 
For those unfamiliar, the company making the "R36S" device basically cloned the internals of the Anbernic RG351MP and sell it in a compact, vertical form factor with a beautiful screen.
 
 I took the latest ArkOS (v.2023-09-20) operating system for the Anbernic RG351MP and swapped a file in the boot partition for screen correction, and it works fantastic on this clone device (same chipset).... far superior to the stock OS.  
 
I added my new and improved superior game libraries with full menu art, added custom bezels for over 200 of the best VERTICAL Arcade games, added 120 ports (incl. getting TMNT-SR to work), plus 8 doom ports, added/fixed tons of 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 "R36S".
 
Includes a whole lot of Playstation, NDS, SNES-MSU1 i.e. SNES-CD, Megadrive-MSU, ScummVM, Arcade (FBNeo/MAME-2003plus), Ported Games (Ports), 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.
38 awesome themes pre-installed. Also I fixed many features of the themes to have proper artwork, etc.
All themes were fixed to properly display all systems. Some of the themes I added include: Epic Szalik, Epic-Cody, Epic Noir, Farfenkugell-Crystal, SagaBox, Nes-Box, Cody-FunkyPlastics, Cody-Destroy, CRTCabBlast-Rogue, CRTCabBlast-Tifa, Carbon, Cody-DarkTeck, Cody-Flux, Crazyboy, Farfenkugell_Lazy, Floyd, Freeplay, GBZ35_Mod, Sonic-Spin, Metroid-Spin, SagaArtBook, SagaParagon, SagaSLice, SagaWorld, Switch, Woody-Cody, Minimal-fixed (with lots of custom added selectable backgrounds), zSR-Cyber-City, zSR-Mario, zSR-Metroid, zSR-PiranaPlant, zSR-Ryu, zSR-Sonic, zSR-Tifa & zSR-Tifa2.
 
Approximately 38,000+ quality games including their game artwork and gamelists in the roms directory are installed. Games have video snap previews, mixart(boxart) and wheel (marquee) art 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:
"R36S" handheld device (new) with box and power cord (transparent orange color) with my 512 GB Samsung EVO Select micro SD card loaded and ready to game (for TF2 slot) and 32 GB Samsung (or Sandisk) 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.  ArkOS allows you to decide which systems to display in the UI/Visible-Systems menu, so you can hide systems you may not care for like some of the older computer based systems.  
 
I left about 1.5 GB free space on the larger sd card available for smooth operation.
