No blowing out the cartridges with this. It is a small ( palm of your hand) emulator with 30 classic NES games installed on it. The bad part is Nintendo recently decided to discontinue manufacturing. any way l enjoy playing them and so do the little ones keeps them busy especially in bad weather.
wasn't that the hot ticket for this last xmas...sold out at stores because of limited production/demand and resold/marked up on ebay for 3x or more...thought they were going to increase production after xmas.....these days it's not beyond some marketing team to limit product production on purpose ...create shortage panic on social media, and perhaps sell out whatever it is.
