Thanks for answering, i am using the last gb studio update(2.0).
so i need to rename my border to "letters_vram.png" and put it on the sprite folder, and then made a scene after with it to fix the error?

No, check the zip. There should be a sprite called letters_vram.png. Make a blank scene with an actor that uses that sprite after the name input screen. It can be hidden.
That file should have a border and a cursor at the end. Modify that part and replace it with your border and cursor.
Also, there are several GB Studio 2 versions. You might have beta1, which has this problem.
