Sega's Game Gear came out in Japan on October 6th 1990. It's now 25-years-old.
To celebrate this fact, Sega has teased what seems to be either a Game Gear theme or collection for 3DS.
The developer shared a 10-second video of whatever it is on Twitter, as you can see below.
The video shows a Game Gear screen at the top while the 3DS's bottom screen browses a selection of game folders.
Sonic the Hedgehog is then launched on the virtual console but the video cuts off before showing anything else.
Hopefully we'll have more details on exactly what this is. It looks like it's just a theme to give you the feel of playing games on a Game Gear.
But another possibility could be a Game Gear collection that comes with a theme and a bunch of virtual console games. We'll let you know either way once we hear more about it.
