Brand new card set for your Powkiddy X55, …uses Rocknix OS, …with over 780+ ports!!!  49 themes!…
For Sale: One (1) loaded 512 GB micro SD card for your Powkiddy X55 handheld retro game system & ALSO includes a 32 GB card for the TF1 slot. Plug the cards in and start gaming. These are plug n play. I used the latest Rocknix OS (as of 10/20/5) and used rom structure and no changes to the es_systems.cfg file so future OS updates are a breeze.  To take advantage of the 16x9 screen, almost all systems have beautiful bezel art (side art) enabled, except those already 16x9 ratio such as PSP. 
 
I added my superior game libraries with full menu art, added custom bezels for all systems including game specific bezels for Arcade systems,  added lots of custom 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 Powkiddy X55!  Includes Ports, Sega Saturn, Sega Naomi, Sammy Atomiswave, Playstation, PSP, Arcade (FBNeo/MAME-2003plus), Dreamcast, Sega CD, SNES-MSU1 i.e. SNES-CD, 3DO, Megadrive-MSU, among many others as listed in detail below.
 
49 awesome themes pre-installed (see photos for many). 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:  AI Hypertocera, A-Touch-of-Glass, Alekfull-NX, Animatics-DX, Arcade-Planet, AX-SlideMix, Artflix-Cobalto, Canvas-ES, Carbon, ComicScrap, CRTCabBlast-Rogue, CRTCabBlast-Tifa, DarkGames, Dynamicbox, EpicMax-Cody, FakeXMB, Forever, HEXA, Metroid-Spin, Minimal (with lots of custom added selectable backgrounds), Next-Level-Remix, PlayStation-X, RCBX, RVGM-BT, Star-Wars, SuperSweet, Tiled, zSR-Cyber-City, zSR-Mario, zSR-Metroid, zSR-Morrigan, zSR-Morrigan2, zSR-PiranaPlant, zSR-Rogue, zSR-Ryu, zSR-Sonic, zSR-Tifa & zSR-Tifa2.
 
Approximately 37,000+ quality games including their game artwork and gamelists in the roms directory are installed. Games have video snap previews, and boxart/mixart 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:
512 GB Samsung EVO Select micro SD card loaded and ready to game (for TF2 slot) and ALSO a 32 GB micro SD card for the TF1 slot - for your Powkiddy X55 handheld.  No hardware is included, just the loaded (plug-n-play) sd cards.  You have to have your own Powkiddy X55 handheld device.
 
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.
 
I removed "ADULT only" roms typical from default setup, but I included them with their artwork in the main roms folder (not visible on device).  So by inserting the 512 GB card into a PC, a simple copy-paste on a pc will put them all in their proper place in the rom system folders to enable/display after reboot.  The "gamelists.xml" files are already setup for them to be added.  Example of these type of games would be mame roms:  newfant.zip, galpanic, bigtwin, plgirls, etc..
 
I left about 1.5 GB free space on the larger sd card available for smooth operation.
