Update 11/6/24:  Newly rebuilt from new EmuElec 4.7 base image!  Superior game library - major upgrade.  Now has over 340 ports with PortMaster!!!
 
For Sale:  One (1) loaded 1 TB micro SD card for YOUR Android Tv Box (models "Beelink GT King" or "Beelink GT King Pro" or "Super Console X King which uses same box").... note: likely will not work on GT King II.  I built this card from scratch using the latest EmuElec 4.7 as the frontend/OS!   Basically plug n play solution here, all setup with my superior assets and expertise.  I repeat, this listing is for the loaded micro SD card only, which is basically plug-n-play.
 
If you have the Beelink GT King which can be bought for about $130 to $140 at AliExpress (or King Pro may be on Amazon), it is very simple to insert my card and use a toothpick in the tiny port on the bottom to depress the reset inside and hold it while plugging in power cord ON 1st BOOT ONLY... after that, the box will automatically boot up into EmuElec with my card inserted (the gaming frontend).  It's easy to exit EmuElec to the Android side of box if you wish, just be pressing Start on main menu, A on Quit, then A on Boot to NAND.  Then it boots up Android side.  My card is also recognized on Android side of box so the standalone N64 Emulator can be used over there too as example.   These boxes with my sd card offer awesome gaming with systems up to and including Dreamcast, Saturn, N64, Naomi, Atomiswave, Playstation, NDS, 3DO,,...and others.
 
I installed EmuElec 4.7 and added my superior game libraries with full menu art, got the ports working, added several awesome themes (some shown in pics), 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 Beelink GT King.  Includes NDS, Sega Naomi, Sammy Atomiswave, Playstation, PSP, Arcade (FBNeo/MAME-2003plus), Dreamcast, Sega CD, SNES-MSU1, Saturn, 3DO, among many others as listed in detail below.
 
NOTE:  The games partition is accessible directly in Windows on a PC for super easy game file transfers/mods/copying/pasting.
 
Games have video snap previews, mix/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:   
1 TB Sandisk (class 10) micro SD card loaded for your box (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 card and a tip sheet.
 
There are 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 arcade systems... other systems have bezels that are system-specific.  I even included the vmu file and nvmem files so Marvel vs. Capcom 2 has ALL characters unlocked (for both Dreamcast & Naomi versions) - see my last photo for character screens.
 
I left about 2 GB free space on the sd card available for smooth operation.
