The data miners in Mario Kart 8 Deluxe have found a big treasure. The Booster Pass update included hidden audio files that revealed the next 16 tracks in the scroll.

Booster Pass is the best thing to happen to Mario Kart 8 Deluxe. The Big Season Pass expands the repertoire of the insanely popular card game with a total of 48 spins (including many old classics). Nintendo offers new content in a total of 6 installments, with eight tracks per part, and although only two packs have arrived in players’ hands so far, the latest update contained hidden files that make it easy to predict the contents of the next two updates.

Thanks to the video above, you can also listen to the musical intros that the game developers added in the latest update. These very short, one-second clips are called “prefetch” files – short pieces of audio that are played only by the converter until there is time to load the real, complete audio clips in the background.

Although the disturbing short musical material has been given a whole new order, the series’ obsessed fans can still easily discover which tracks the music can be connected to. Those with an eye can quickly discover that instead of 16 tracks, only 15 are listed, but one of the songs is used by two different tracks. With that said, we have the sites ranked in the next two Booster Pass. Of course, the legendary Rainbow Road wasn’t left behind either! The list is attached here:
