+
+ basic information
+ https://gbatemp.net/threads/the-c2-color-game-console-an-obscure-chinese-handheld.509320/
+
+ "The C2 is a glorious console with a D-Pad, Local 2.4GHz WiFi, Cartridge slot, A, B, and C buttons,
+ and has micro usb power! Don't be fooled though, there is no lithium battery, so you have to put in
+ 3 AA batteries if you don't want to play with it tethered to a charger.
+
+ It comes with a built in game based on the roco kingdom characters.
+
+ In addition, there is a slot on the side of the console allowing cards to be swiped through. Those
+ cards can add characters to the game. The console scans the barcode and a new character or item appears in the game for you to use.
+
+ The C2 comes with 9 holographic game cards that will melt your eyes."
+
+ also includes a link to the following video

+
+ TODO:
+ identify CPU type, and if the system ROM is needed to run carts or not
