There is a translation/dubbing for this game in Brazilian Portuguese. I believe it was published by Sony Music Entertainment Brazil. If it helps, I have the original CD in excellent condition.

So hey, meu amigo.
Speaking as someone that played that game in Brazilian Dub, and would love to play it again.
If they added the Brazilian dub i'd buy it on GoG on a heartbeat.

However, i feel like that there is a bigger chance of it happening if we do it ourselves.

Look, neither the Steam or the Gog version have the Castellano dub of the game and this person on Steam found a way to put the Castellano language in the game. If you could get in contact with them, maybe they could give a guide on how to do that.

Eu baixei uma versão dublada e copiei os arquivos do iso na pasta de instalação
