Does anyone have access o copy of a HQ version of "Unstoppable" & it stems tracks?

Hi! I'm new to this subreddit, I've been a fan of MS since late 2013. I'm now trying reaching other people with this post because I've had hit an end point, were of all the things releated to demos and early versions, I cannot find somewhere to purchase or download a digital HQ copy of this song, just the reuploads.

I'm aware that previously another user asked about this and there's an existance of an a archive of Ultra Rare Vol. 0. But what I'm looking if for a lossless version of it, and also the original stems that Luis provided in 2012 via Soundcloud when he made a remix contest.

I've tried with waybackmachine but there's not file, only a snapshot.

I hope that an older and wiser fan that has this files. My intentions is to archive all the music releated to MS / Luis and share it with everyone (obviously in the most legal / respectful way possible); something like Sledbed it's been doing with The Brobecks / Dallon Weekes & Co. releated.

Thank you for reading! TL;DR: I'm want access to the most HQ of the single and the stems of the song "Unstoppable".
