This script uses less of scene.org's bandwidth, but in 2020 I actually recommend using

https://github.com/p01/pouet.net.user.js/blob/master/prodScreenshot.user.js

which adds thumbnail screenshots directly to the r###lts page, and

https://github.com/p01/pouet.net.user.js/blob/master/ytEmbed.user.js

which lets you watch the YouTube video of a prod without needing to leave pouet.
