The Nes Mini Classic, a console with 30 built in Nintendo Games has been hacked to play roms, sounds awesome, heres more info:

"I just got word from GaryOPA over at that the NES classic is hacked, even game ROMs can be added to the existing kachikachi emulator collection. The method used is in the forum post here. I guess someone finally figured out how to use Plutoo's descrambler released in November 2016 and how to flash the decrypted content back to the NAND. Progress!"
