Chrono Trigger/Version differences

A few things differ from the original SNES version in the newer PlayStation and Nintendo DS versions. For the PlayStation, most identifiable is the Extra Mode and improved graphics, as well as the cinematics. For the Nintendo DS, the game offers additional content, a WiFi mini-game, improved programming, and cinematics from the PlayStation version. Also, much of the text, including names of enemies and items, in the Nintendo DS was revised.

Extras Mode
The Extras Mode is a PlayStation exclusive feature.

Arena of the Ages
The Arena of the Ages is a WiFi mini-game that adds some replay-ability to the game. It is a monster training and battling mini-game that also allows players to earn rewards.

Lost Sanctum
After the Black Omen appears in the sky, two Gates will appear, offering some optional DS exclusive sidequests with great rewards.

Dimensional Vortex
In the Nintendo DS version, one exclusive area exists called the Dimensional Vortex. The Dimensional Vortex is a dungeon with that can only be accessed after beating the game at least once. When you return to your saved game, three new Gates will have appeared in separate time periods (12,000 B.C., 1000 A.D., and 2300 A.D.).

Like other dungeons in the game, the Dimensional Vortex varies depending on which time period you're in when you pass through the gate. Each time period specifies the reward from completing the dungeon: a permanent upgrade to one of three characters: Marle (the past), Chrono (the present), or Lucca (the future).

After completing all three different versions of the dungeon, a final, new, boss encounter is unlocked (as well as a new ending).

Time's Eclipse
Time's Eclipse is the final area of the Nintendo DS version of Chrono Trigger. Within it is the final boss of the game. To reach this area you must first unlock and complete the Dimensional Vortex dungeons, and then use a new Gate that appears at the End of Time.

Names
There are major naming differences between the original SNES release and the Nintendo DS release. The PlayStation version also had some changes, but uses most of the SNES names. And note that Frog has lost his Anglo-Saxon accent in the DS version.
