Recent Updates

2018-11-24: More notes on 魔王 as a term (towards the end of Chapter 1), and an actual explanation for Specchio's peculiar line when handing out magic (see Chapter 8).

2017-10-28: A handful of minor revisions, most notably adopting the spelling "Specchio" to match the Italian word for "mirror" that the name likely came from.

2015-09-07: Some miscellaneous minor revisions, plus a bit more detail and better accuracy on the techs page.

2015-03-01: I've been feeling increasingly dubious about the name "Demonic Vessel" for the 魔神器 ("Mammon Machine"), so after taking another look at it I've decided on using "Nether Relic" instead. Same general idea, but I think it sounds less cheesy. Similarly, Crono's "Sky" seemed too bland (and perhaps overly specific anyway), so it's now "Aether". That sounds more appropriately mystical.

Meanwhile, I've added much more information about enemies and what to best kill them with, and meanwhile summarized regional monster data in the story text. Some of the sections have also received much-needed fleshing-out, particularly the earlier dungeons.

Also throw in more information on the other various ways of reaching Lavos, the multiple alternate endings found (mostly) by beating Lavos at different points in the storyline, and noting the value of the internal storyline progression variable during the course of the game largely because it's relevant to that. In some cases, this has resulting in adjusting the chapter boundaries to be more accurate, though in most cases the difference would not be observable during play.

So, at this point, I'd say it's basically complete. Feel free to keep asking questions, making suggestions, or requesting any text that I've skipped, though.

Storyline

The game has its own chapter names that appear right on the save files, making it easy to tell more or less where in the game each one is. Somehow, this stunningly obvious bit of convenience remained a rare feature in games even years later.

Non-Story Information and Translations

Various Notes

• I've kept the layout of the original text as much as possible.
• Lines that are colored like these are my comments, anything in gold denotes actions and such that the dialog doesn't explain, and this teal is for messages from the game (e.g., "You got a potion").
• Chrono Trigger barely uses name suffixes name suffixes (outside of a highly respectful one that's easily adapted), so, for this game, I've edited them out of the translation.
• Significant sections of dialogue depend on who is in your party, or which option you choose. I've decided to mark alternate flows with colored borders and give explanations individually. The scenes where your party may vary generally have various roles that will be filled by the characters present. In some, the game apparently decides who to use for each role by going down a preset list and picking the first available character. In others, it just picks whoever is, for example, second in the party order. One result of this is that in many scenes, a character will always fill a given role if present, regardless of who else is in the party or in what order. Another is that some characters may never fill certain roles. Note that Marle and Lucca tend to take priority for getting lines, that Crono never talks except in a particular alternate ending, that Ayla tends to be low priority, and that the optional character hardly ever speaks.
• Since I feel like it, and it sort of contibutes to the mood, background music is indicated by the OST track number (first time only) and track name. For example, the title screen's music is 1-1 予感 (Premonition), meaning track 1 of disk 1, entitled 予感 (which means "premonition"). Some of the track names are difficult to translate, and these are noted. Sound effects are also noted now and then when appropriate.
• Original text, my translation, and the English version text are displayed side-by-side in columns for easier viewing, and to allow comparisons with the official translation. I'll generally refer to the original as the JP (Japanese) version, and the official English version as NA (North American).
• Even sections marked as complete may still have oversights, typos, or other errors. I'm trying to eliminate those, but nobody's perfect.
