Nice! I'm gonna test this later today, it looks really cool!
EDIT: I made a level using this theme! I bet it looks weird without the mod :P
Name: Super Mario Odyssey
If anyone plays it and gets stuck at the first part, I made a contraption that gives you a key if you go close to the door as costume Mario... or in this case, Mario with the Builder outfit c;
Nice! If you want, you can upload it to SMMDB and make a new thread on it.
Old 3DS XL info:
I used to have a 3DSafe A9LH V11.3.0-36U with Luma in my CTRNAND. Since ReiNAND Reibooted and Re-Reileased, I "switch"ed back.
Right now, I have boot9strap with Luma 8.0 as my CFW. Though, I'd like to see other CFW's for B9S.
