NOTE:  Does NOT work with the new OLED models!  Only the older non-OLED models, but hopefully there will be a new Batocera version that will in future.
 
5/2/23 UPDATE:  This is my new PlayStation-3 (PS3) emphasis card for the Valve Steam Deck (Batocera 36 for Steam Deck)! ...plus includes ~71 GB of  "best-of"/"select" games for many other systems.  138 PS3 games!.... plus ~3,400 others - best of the best.  Game list in link below, check it out:

For Sale: One (1) loaded 512 GB Sandisk Ultra microSDXC UHS-I memory card, for the Valve Steam Deck. Plug it in to your Steam Deck's micro-sd slot on the bottom, hold down the Volume down button as you turn it on, then a boot prompt appears. Select boot from SD card and then the system (latest Batocera 36 for Steam Deck) boots up and you're golden... start gaming! It's awesome as it is completely independent from your Deck's internal storage... keep that for Steam Gaming. Batocera is the way to go for emulation / retro gaming on the Steam Deck! 
 
I take pride in building the very best cards and I put countless hours into this one, as Batocera on the Steam Deck is fantastic! You will NOT be disappointed. I used the latest techniques such as squashfs, gamecube compression via Dolphin, etc. to optimize the 512 GB of space! Note: If you prefer more complete system sets, more gamecube, etc. then check out my 1 TB card listing.  However, this 512 GB "PS3-emphasis" build does have a lot more PS3 on it then my 1 TB card for the Steam Deck.  Buy both if you like... think of the sd cards as game cartridges... you can just swap them out when unit is off.   :) 
 
20 Themes pre-installed, many of which I fixed issues. All themes display all systems nicely. See my pics which show several of these themes.  All PS3 games have been run to compile PPU modules and confirm boot.
 
Approximately 3,500+ quality games including their game artwork and gamelists in the roms directory are installed. Games have video snap previews, boxart/mixart, and wheel (header-marquee) art, typical. For Arcade Games (i.e. FBNeo and MAME), Vectrex, and a few other systems, game-specific bezels were added to system and enabled through Batocera's decorations menu. Almost all systems have beautiful Batocera bezel art where appropriate. With the size of the screen, this is fantastic! CHEATS have been installed available through the retroarch menu for many popular systems.
 
All games have video previews that play as you scroll down through the game list on each system. Awesome menu background themes loaded which can be easily switched up.  The Arcade Favorites collections has hundreds of the best arcade games (from the thousand+ on system).
 
I left about 4 GB free space on the sd card available for save states and smooth operation. Also, Batocera can be updated on the device easily but it requires about 3 GB free space temporarily while its downloaded, so keeping 4 GB free makes it easy to update in the future if desired.
