Dunno if this would go here or if this would even be a proper place to ask this, but does anyone know how the IR carts (HGSS/BW/B2W2) work with Twilight Menu? For example, if I have HeartGold in my cartridge slot and am running SoulSilver on my DSi/3DS with Twilight Menu, can I then use the Pokewalker with SoulSilver by using the HeartGold cart?
I ask because I always wanted to do custom Pokewalker routes for a HGSS romhack, but it would be completely pointless without some way to actually access the Pokewalker.
