The Yogscast Voltz, Help Please

[nevv]

Ever sense I watched there first episode I have dreamed of getting voltz BUT being the misleading jerk, they used a custom voltz and that means its impossible to have the same mods. So when I finally got the voltz mod pack I was excited and then my heart basically dropped when I couldn't fine the same stuff (blast craft and stuff like that) SO I'm reaching out to the public for help on how to get there voltz (preferably a link) or if someone would be kind enough to make one, They both would be extremely appreciated and I believe many others would love to play on the same modpack . Thank you for reading this

i think they were just using a very old version of voltz at first (1.0.x ?) then they modded it to show off a few different things.
