Microsoft‘s first-gen Xbox released almost 20 years ago, yet there are some things about it that are still being discovered today. One of its original developers recently revealed an easter egg.

According to sources, the Easter Egg can be found when you burn a CD to your Xbox’s hardware. When a prompt asks you to name the album, type in, “Timmyyyyyyyyyyyyyyyyyyyyyyyyyy!” You don’t have to count the number of “y”‘s here; simply fill out the entire field and then replace the last “y” with an exclamation mark. “I didn’t really expect it to be found, not unless the source code leaked or somebody reverse-engineered the Dashboard,” said the developer in an interview. Once the CD is finished being copied, head to “Settings” and hit “System Info.” Xbox will then reel out a screen showing a list of members of the Xbox Dashboard team. The designer mentioned there’s at least one more easter egg that he thinks people haven’t cracked yet, but he hasn’t yet shared its details. Perhaps we’ll need to wait another 20 years.
