The research, conducted by gaming site Solitaired, analysed data from popular technology trade-in site CeX to find which old video games will earn you the most money if you have them lying around at home.
They looked at the most valuable games for earlier generation consoles, including the Nintendo DS which was released 22 years ago in 2001.
And it turns out that selling just a couple of old games you haven’t played for years could net you enough to buy a new console.
Here are the DS games you should be searching your cupboards, drawers and shelves for.
