What does the Pirate and Nate say when trying to open the gate in Chapter 5?

Solution 1:

According to this GameFaqs post, Nathan and the Pirate are speaking in the Indonesian language. Using Google Translate, their conversation is roughly translated to:

Pirate: Hello?

Nate: Open the gate

Pirate: Who is this? Speak now!

Nate: Ah crap.

Nate: Damn you! Hurry up and open the door

Pirate: [undetermined swear word]1


1 This one is difficult to determine. Any translator is unable to give me a proper English equivalent, and only outputs the same text.

"Tai" more than likely translates to a swear word or another explicit phrase of some sort. Based on the Dake's Fortune script, "Tai" is used three other times by Eddy Raja in context of frustration or anger:

  1. Tai kamu (used twice, no proper translated)
  2. Tai kucing (used once, does translate to "damn you")
