I am getting a good experience of working on Encyclopedia Pokémon Esmeralda of creating Legit Events and I would like to make a legit one. These are the Methods where Pokémon can be caught:
1 (A-B-C-D) - Normal NDS or GBA - This type is the most common and will be seen on wild/legend encountered pokemon in nds/gba games.
2 (A-B-C-E) - Wild GBA - This type is less common and will be seen on wild encountered pokemon in gba games. It is unclear whether GBA legends will be seen with this type.
