Nintendo has filed a patent for a software emulator that could bring its Game Boy games to phones and other devices.

The patent (via NeoGAF), which was filed in June, describes emulating Game Boy, Game Boy Color, and Game Boy Advance Games on cell phones, as well as seat-back displays of the type you see on some airplanes and trains.

However, the patent doesn’t mean Nintendo plans on actually bringing its games to phones and other platforms. It’s an updated version of an older patent, which is probably meant to just secure the option for the company.

Nintendo has explained multiple times that it’s not bringing its games to mobile devices anytime soon, and earlier this month, it touted the sales of Super Smash Bros. for Nintendo 3DS and Monster Hunter 4 Ultimate as proof that dedicated handheld gaming devices are here to stay.
