Okay, so I came across a used PokeWalker at a tech shop today and had the urge to buy it out of curiosity. It turns out that the old player's name (PHILMAV) is still on there somehow. As I was heading home a pidgey decided to come along on the aforementioned player's PokeWalker. I wanted to figure out a way to get that pidgey out of the pokewalker. I can't be bothered resetting the gadget, because I had the most trauma-equivalent experience when I was using the 3DS Transfer tool. Here's the ROM of PHILMAV's PokeWalker Data.
