Sup guys I started playing Fire Red on my old gba because I bought one and bought a pokemon colosseum bonus disc so I can get jirachi in the game and I tried using lugia just to catch jirachi and it worked but no pokedex entries thats kinda odd although if you guys played Fire Red you will love it!!!
Pretty sure jirachi wouldn’t show up in fire red’s pokedex.
It would because fire red is the remake of Pokemon red, which was made after 3rd gen games when jirachi was released.
Also, maybe it’s because you don’t have national dex
