>>48696626Jesus Christ... R4i is like $15. I can see people paying a ton for gens 3 and 5, since you absolutely need a real cart to transfer pokes up to the next gen. 4 though, you just need a second DS and flashcart to move up to 5, and flashcart plus GBA game works for Pal Park.
HGSS at least there's some excuse, you absolutely need the real cart to use a Pokewalker since the IR transmitter that talks to it is in the cartridge itself.
