Glued with superglue. Is there any possible way I can remove these and its traces?

Hrm. Thats a toughie. Remove as much as you can very carefully with your fingernail then hit that sucker with some nail polish remover on a cotton ball. That should remove any sticky residue left. Good luck.

Ouch. They're pads to stop the screens touching each other? Just trying to see their thought process... 'I'll ruin my 3DS with superglue to protect the screens!!'
No idea how to remove super glue though, but good luck, & if you could, show us how well it turns out.
