Memory Code

The Memory Code is a feature in Xenosaga Episode III. It allows the player to rewatch cutscenes they have previously viewed on their current save file.

Overview
The Memory Code can be accessed from the 'Data' option on the title screen. A save file is required to access the Memory Code; if the player skips loading a save or has no save data, the Memory Code is inaccessible.

In the Memory Code, cutscenes are grouped into 'events'. The length of an event can vary - some events only contain one cutscene, while others may contain more than twenty. The player can either view cutscenes individually, or can play all of the cutscenes in an event in sequence. Due to this structure, cutscenes are not immediately available for re-viewing after they play in-game; instead, all of the cutscenes in an event will be unlocked for viewing when the last cutscene in the event has been viewed on the current save file. Events are then grouped into one of ten chapters, from Chapter 1 to Chapter 10. While the majority of these chapter divisions match how they are presented during gameplay, there are a few discrepancies. The in-game Prologue chapter is grouped together with Chapter 1 in the Memory Code, while Chapter 10 in the Memory Code is treated as part of Chapter 9 during standard gameplay.

Cutscene types
The Memory Code divides cutscenes into three types of scenes based on their presentation and how they are stored in-game. The type of a cutscene is denoted based on the color of its title; these types have no known official names.
 * Cutscenes with white titles, or , are the most common type of cutscenes. In these cutscenes, characters use stock animations rather than fully animated ones, and dialogue is delivered using textboxes rather than standard subtitles; due to this, disabling subtitles in the options has no effect on these cutscenes. Pressing Select allows the player to toggle between Auto Mode, which causes textboxes to advance automatically upon completion of their respective voice line, and Normal Mode, where the player must manually press a button to advance dialogue.
 * Cutscenes with blue titles, or , are cutscenes that are rendered in real-time. These are much closer presentation-wise to cutscenes from earlier Xenosaga titles as well as the Xenoblade Chronicles series, with full animation rather than stock ones and standard subtitles that are either visible or not depending on the player's selection in the options.
 * Cutscenes with gold titles, or , are cutscenes that are stored as video files on the game's discs. They are mostly identical to Animated cutscenes, but are generally capable of greater visual feats due to being pre-rendered, and their pre-rendered nature gives them some minor functional differences.

Swimsuit Mode
Swimsuit Mode is an toggleable feature in the Memory Code unlocked after beating the game. It allows the player to view most of the game's cutscenes with the main seven playable characters (as well as Allen) in their swimsuits rather than their standard attire. The swimsuits visible when Swimsuit Mode is enabled are dependent on which swimsuits have been obtained in the loaded save file - if only Shion's swimsuit has been obtained in-game, then it will be the only one visible when Swimsuit Mode is enabled. The swimsuits replace characters' clothing in most conditions, including when they are wearing clothing aside from their usual outfit (eg. Shion in her Scientia outfit during the prologue), or when an identical model is used to represent a version of that character from the past (eg. Shion when she was still dating Kevin in flashbacks at the start of Chapter 4, or the past version of Jin on Miltia fifteen years ago).

Notably, Swimsuit Mode cannot be enabled on Pre-rendered cutscenes, as the dynamic nature of unlocking swimsuits necessitates cutscenes to be rendered in real time.

The location of each character's swimsuit is listed below:
 * Shion's Swimsuit:
 * KOS-MOS's Swimsuit:
 * chaos's Swimsuit:
 * Ziggy's Swimsuit:
 * MOMO's Swimsuit:
 * Jr.'s Swimsuit:
 * Jin's Swimsuit:
 * Allen's Swimsuit: Complete the game. Confusingly, this costume is not unlocked on the 'Game Cleared' save file made after viewing the game's ending; instead, the player must load it and then create a new 'Cleared Data' save, which will have Allen's swimsuit available.
