I feel like I should post this, because the main creator isn't interested in SMBX much now.
Super Mario Bros. X 64 is an old episode made by Rainbowyoshi (now known as rainbowyoshismbx, you can find him on YouTube and Minecraft forums), h2643, Squishy Rex and raio gelo. This episode is almost 2 years old, so don't expect anything mind-blowing in it.
Credits are in the .txt-file "credits".
I hope you will enjoy this episode!
