Product Name: Snes super Nintendo please retail read
This super Nintendo system plays American super Nintendo games European and Japanese super famicom games. It comes with what you see in the photos two new controllers AV cable retail and power cord. Mario kart famicom version and Monopoly I went to test the system and a fire rate up and worked fine but for some reason there is no audio I don't know if it's the AV cable it's the only one I have so I can't ask a different cable but I did test two different TVs and there was no audio but last time I played it about a month ago I did and the cable does have some slight damage as you can see in the photos so there's a chance you might need to replace the cable or have to repair the super Nintendo system.
