TR-49 Guide: All Codes List

With 67,600 potential combinations, TR-49 has lots of codes to go through. Finding the relevant entries for achievements or solving the mystery is difficult if you don’t know what records you are looking for. This is a list of all the codes in the TR-49 that are relevant to the story and should only be used if you get stuck. There’s a genuine joy to investigating every mystery and solving this yourself without help. But if you get stuck and can’t proceed any further, this list prevents you from going through every possible combination just to get a hint (ie. AA00, AA01, AA02).

Machine Codes

These are the command codes that allow the machine to perform specific functions. Some, such as PR37, allow you to view a previous entry without manually inputting the code again. Others, like CC11, sometimes unlocks additional content on code entries that can provide more clues. You run into most of these throughout the story as they pop up in menus.

Aliz Caulderly

The daughter of the creators of TR-49. She made additional notes on some entries under the code AL12.

Academicalist’s Journal

These are journals that discuss various topics but are a key method for discovering more titles and authors. The links to other entries helps you find other documents, especially if they are referenced often.

Beatrice Dooler

One of the two creators of the TR-49 machine. She has several entries that discuss her life and her code, BE47, unlocks some notes on certain entries. She also has the password necessary to delete entries in TR-49, the focus of the game.

Cecil Caulderly

The other inventor of the TR-49. His code, CC11, unlocks information on certain entries.

Cecil Erstwhistle

His entries provide a few clues into Quentin Lemerchant along with some codes and titles.

Dorothea Pemberton

Another author whose work is referenced in several entries, allowing you to find her easily. Her works are also tied with other authors.

Emma Meyfleur/Kendrick

You might find this author as Emma Kendrick but she also has entries under her maiden name, Meyfleur. She’s also the author of the book you must identify and destroy.

Hammerstone Press

Their works are some of the early ones you find and they link to a few other authors as well.

Isambard Arklovich

He wrote the “Rampage” series and his works are one of the easiest to fully catalog and identify. “The Glen of Galileo” is also linked to other works.

Joshua Silverton

Several of his works are linked to other authors, allowing you to find their entries and gain more clues.

Literary Review

One of the earliest “authors” you learn about and their works are vital sources of authors’ names and titles.

Pinkin Kendrick

His marriage to Emma Meyfleur is why some of her entries have a name change.

Pierre Letour

One of the easiest authors when it comes to finding their work and naming them.

Quentin Lemarchant

An author whose work links to other authors and is easy to fully catalog.

Reverend Alonso

Not many works to record, making him easy to fully catalog.

Church of the Rampaging Christ

Another “author” with few works, making them easy to catalog.

Thaddeus Detzer

An author who doesn’t have much of a presence compared to the others whose works are in TR-49.

Ursula Letour

Related to Pierre Latour but isn’t as involved with the story as the others.

Xavier Youngman

You will find some of his works quickly as XY is one of the few guaranteed code combinations given to you at the start.

Books

These books aren’t necessarily relevant to the game but they can help you reveal titles or authors that you may not have found yet. Some of these titles speed up your discovery of other authors and shouldn’t be ignored.

These codes should put you in a better position to earn every achievement and solve the mystery without much frustration. Check out our TR-49 review to hear our thoughts on the game if you are wondering how tough the mystery can be.
