For Sale:  One (1) loaded 512 GB micro SD card for YOUR Android Tv Box (models "H96Max X3" or "HK1").... for ones which have a cpu = Amlogic S905X3 with 4GB SDRAM.  I built this card from scratch using the latest EmuElec 4.5 as the frontend/OS!  The circular shaped "Kinhank Super Console X Max" is basically a H96Max X3, so that model would work too.  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 H96Max X3 (or HK1) which can be bought for about $50 to $60, it is very simple to insert my card and use a toothpick in the headphone jack 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 and affordable gaming with systems up to and including Dreamcast, N64, Naomi, Atomiswave, Playstation, NDS,...  Older systems emulate fantastic, these newer systems I just listed are pretty good with some varying result depending on games... similar to handheld performance like a Anbernic RG351MP, RG353P, or RG503.  I would say these two boxes are much better than a raspberry pi 3B+, and performance on newer systems is almost on par with the much more expensive raspberry pi 4.  I use the H96Max X3 personally.  I have used the cheap 2.4ghz wireless ps2 style controllers, but I highly recommend PS4 controller using bluetooth (pairs easily)... the knock off PS4 controllers I have used are great too.
 
I installed EmuElec 4.5 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 these boxes.  Includes NDS, Sega Naomi, Sammy Atomiswave, Playstation, PSP, Arcade (FBNeo/MAME-2003plus), Dreamcast, Sega CD, SNES-MSU1, among many others as listed in detail below.
 
NOTE:  The games partition (EEROMS) is accessible directly in Windows on a PC for super easy game file transfers/mods/copying/pasting (nice benefit of EmuElec).
 
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:   
512 GB 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 almost every game... some bezels 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.
