How to wright something in game

as titel i have a game duel carnival (jpn)


but of course this is not the code so help

The game probably uses the software keyboard for this, it’s unimplemented, and that makes this game feature inaccessible for now.

oh ok thanks but is there a way to change it like how you choose your name its ok in other games

There’s no way to change this.

ok thanks for your help
