Yeah, but the background is a model and its hard to make models. If anyone would like to make a background for the 3DS version (which isn't a model, but layered images), then please tell me as I'll add it to the first post.
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.
