While a lot of players are still having trouble finding and getting their own NES Classic Edition, modders have managed to open up the possibilities of the plug-and-play retro console. As you can expect, none of the changes are approved by Nintendo.
Usually, the device comes pre-loaded with 30 games but modders from Russia and Japan claim to have bypassed the system’s security with one adding more game to the library and the other having the console recognise an SD card reader.
Russia’s Madmonkey have managed to add additional games bringing the game library up to 60 games.
Japan’s Honeylabs managed to have the console recognise an SD card reader which opens up possibilities.
While both groups have released tools allowing others to hack their own NES Classic Edition but doing so voids the console’s warranty, of course. So people looking to mod their own should exercise caution. Also, those on the look out for NES Classic Edition consoles should purchase only from reputable retailers to be sure they are getting what they expected.
