Basicly, i want to get the mystery gift/event exclusive pokemons but all the tutorials i see r for the 3ds, and the phew that r for the ds/ds lite, dont work on the dsi, im going nuts trying to get this to work, not 1 single solution out there that works for the dsi, thought of using cheats but they also didnt work, has anyone been able to get them on the dsi? is it impossible?
