PFFF WHY I NEED UNDERTALE ON WII U? XDIf your 3DS has cfw, you can load NDS homebrew with the twloader
I think NDS is a odd decision but is not bad, put it on flash carts, play it on NDS or 3DS, emulator, and now probably WII U VC with rom injection. Now what? YOU GOT UNDERTALE ON WII U. Sound good?
i don't have wii u
