Hi, I bought the game, I have two questions about it, does anyone know if it will have more translations, and if there are more translations, will any be in Portuguese? and about the game routes, is there any slave route? if so how do i do it?

Here you are, translation software.
Follow the instructions. 
Manual translation works best. 
Make sure to double check your work!

Basically use Google Translate or other translation software and copy/paste.
