For the new super affordable, "BATLEXP G350" Handheld gaming device.  The handheld can be found for about $40 on AliExpress (sometimes less with coupons) or find one on Amazon... and my micro sd card set turns it into an amazing device!  For those unfamiliar, the company making the device is rumored to be Anbernic as believed by many online.  My card set for it has over 700 Ports, many new ones recently released on PortMaster!!!!
 
For Sale: One (1) loaded 256 GB micro SD card for your "BATLEXP G350" handheld game console/device (runs from TF1 slot)  Plug the card in and start gaming. This is plug n play. I took ArkOS 2.0 (v.2025-03-30) operating system for the Anbernic RG351MP and swapped a file in the boot partition for screen correction, and it works fantastic on this device.... far superior to the stock OS.
 
I added my superior game libraries with full menu art, added custom bezels for over 700 of the best VERTICAL Arcade games, added over 705 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 256 GB card for the "BATLEXP G350".
 
Includes 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.
36 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, Nes-Box-Wood, CRTCabBlast-Rogue, CRTCabBlast-Tifa, Carbon, Cody-DarkTeck, Cody-Flux, Crazyboy, Farfenkugell_Lazy, Floyd, Freeplay, GBZ35_Mod, Metroid-Spin, SagaArtBook, SagaParagon, SagaSLice, SagaWorld, Switch, Replica, 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 17,000+ 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:
256 GB Samsung (A2 V30) micro SD card loaded and ready to game (for TF1 slot - I may provide Sandisk brand depending on stock)) - for your "BATLEXP G350 " handheld.  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.  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 GB free space on the larger sd card available for smooth operation.
This micro SD card has the following systems on it, and I list the approximate game count below:
