Welcome to the official SM DistorteD thread.
First of all, here is where you can download the game.

Thanks to Zagh for the hosting!
NOTE: THIS IS A CUSTOM STEPMANIA BUILD. NOT JUST A THEME. DO NOT EXTRACT INTO YOUR REGULAR 3.9 SM FOLDER. THANKS!
WHAT IS IT?
A stepmania version of Beatmania DistorteD. In other words, Stepmania gameplay + Beatmania IIDX 13 looks.
WHO DID IT?
Me, AJ 187 (stepmania build modifying), and some advice from diekatze and others.
WOW SWEET CAN I MAKE MY OWN?
Sure, BUT.. you MUST credit me first.
I MEANT THE CHARTS. CUSTOM ONES.
Ooh, well in that case.. ah, you need to modify the BGA in STAGE and add a graphic for it in _songname. The BGA script should be fairly simple, since there are examples there. Other then that, put it with a templated banner and background, and it's all good! I will give a much better tutorial on this if demanded.
Okay, now for some screenshots.

ScreenSelectMusic
NOTE: This is about 95% complete. Most of the changes regarding fonts. Also, the menu timer is not real. It is just a static graphic.

ScreenGameplay
NOTE: Background videos show up on the right-hand side. If there is none available, the background of the song will show up instead. Also, the background of shows up on the left-hand side as well. Also note, the left-hand side is a conditional metric because you cannot display the background and the background video on the same screen here.

ScreenStage
NOTE: This is far from complete. It will soon mimic the IIDX DistorteD one very closely, this is just how far I got. Also using conditional metrics for the text.

ScreenSelectStyle
NOTE: Badly needs functions. The menu selections actually work, by the way (And Beginner has its own screen).

ScreenSelectMusicBeginner
NOTE: Needs some more elements, otherwise this is coming together nicely.

ScreenStageFree
NOTE: No animations.

But however it is working!
