So I did this back in September out of pure boredom. 40 hours of smashing my head into a keyboard resulted in this remaster/transcription of the Great Pyramid theme from Serious Sam: The First Encounter.
It's much clearer than the original, and sounds as close as I could get to the original, given how the artifacting and compression of the original track made a lot of the smaller nuances of the piece harder to hear, and I had to sort of try really hard to piece together some of the less distinct notation.
This is the shorter of the two versions I did, the other one was just all the versions of the Great Pyramid Theme in a big medley of "Oh hey, it got FASTER!".
(Also, compare it to the original track, you'll see the difference!)
