Bag item sprites from Pokémon X/Y

[E-Man]

I hate to tell you this, LDEJRuff, but it's currently impossible to rip sprites from 3DS games. Since true system is fairly new, it could take a while to get the emulation process just right. The same applies for any file extraction techniques.

This topic describes the situation better than I can. How about taking a look?
