"Cosmo Black" original 3DS, not the exact same one as the one I got back in 2011 because that one died randomly and I had to get it fixed by Nintendo.
"New Black" New 3DS XL, got one after the hinge on my "new" "original 3DS" broke. then got a second one later after....
"Animal Crossing: Happy Home Designer" New 3DS, because I liked the smaller model. but then I replaced it with the new XL again, but I still have it.
"Aqua Blue" original 3DS, my brother's old console before he got my "old" "new XL".
"Crimson Red" 2DS, the only console I got specifically for hacking, and was my first experience with emunand and custom firmware.
I have all of these right now, and all of them have arm9loaderhax.
