How to be able to use items on subway battle pkmn black 2

[josepokemon1290]

Hello, I want to know how to be able to use items in battle subway of pokemon black 2, specifically supertrain doubles (the pink one), maybe with hex editing or something better idk. If you want, please notify me if you solved it sending me an email to cebo512correo@gmail.com. If you want, make a simple video of the cheat working, it will be great for me to see it working before trying, but is optional.
