Here's my setup:
From left to right:
R: Retail Downloads
N: NES
M: Misc.
A: GBA
S: Game Gear
D: Demos & DSiWare
C: 3D Classics
3: 3DS Download Software
G: GB/GBC
My opinion on the rest. Serebii, yours is far too messy, Aneres is far too tidy, Ike... better than before and Cube probably has the nicest one to look at.
You can slightly notice it in the top right corner of the screen.
