Glossary ROMs

The Glossary is an in-game compendium of information about characters, enemies, and guardians, accessible from the title screen or via the Ruins Encyclopedia application. Entries are sorted by field, with an extra page for Main Characters.

The Glossary normally begins blank; to fill it out, you must collect ROMs (or chips) for each entry. ROMs are small items that look like retro game cartridges, each with a specific color and label that indicates rarity. Most enemies will drop their corresponding ROM when slain the first time, and most NPCs and will give you their ROM after talking to them the first time. However, rarer ROMs for sub-bosses, guardians, and other special characters are scattered and hidden throughout the ruins, some requiring you to pick them up using the Hand Scanner.

ROMs will not appear (either in-world or as drops) until you obtain the Ruins Encyclopedia app from Fobos. The app does not need to be loaded to continue seeing and obtaining ROMs.

The following icons represent the rarity of ROMs.

List of ROMs
The following is a complete list of Glossary ROMs, sorted by the categories in which they appear in-game, their rarity, and how they can be obtained. The glossary entries themselves can be found on their respective pages.
 * Drop indicates that the ROM will drop when the corresponding enemy is defeated
 * Talk indicates that you will automatically receive the ROM upon exiting an NPC or shop room for the first time.

Known Issues
In the initial release, Main Characters #19 and Dark Star Lord's Mausoleum #3 (Basilisk) were unobtainable. As a result, the corresponding Encyclopedia Completionist achievement was also unobtainable. The Basilisk ROM was patched in a later release. Main Characters #19 is still unobtainable, but apparently not required for the Encyclopedia Completionist achievement.

Before version 1.7.7.2 Main Character entry # 13 Hiner could become unobtainable on a given savefile if you visited his shop before acquiring the Ruins Encyclopedia.
