This is a sub-page of Proto:Chrono Trigger (SNES)/Area Differences.


Prototype Final
Fancy fountains... but Medina is kind of bland. The present we all know and love!

The map of 1000 AD underwent several minor changes, and at least three major ones:

  • Zenan Bridge is broken. While this does indeed happen in the final during 600 AD, at no point is it in the same state of disrepair in 1000 AD. Since it was still possible in the latter era to reach the southern continent by ferry, the programmers undoubtedly deemed it pointless to keep it broken.
  • Medina underwent a few changes. First, the well in the center of town was replaced with a more elaborate town square, while two houses near the northern part of town were removed. One of these was made into Melchior's house, which had yet to be placed in its normal location just outside Heckran's Cave. The small patch of forest where it would later be relocated was slightly larger, and several trees were also added in the final.
  • Choras downsized, evidently. The two houses in the northern part of town were reduced to a single house in the final.
  • The fountains in the center of Truce and Choras were considerably larger in the prototype. Modified versions of the tiles surrounding the fountain were actually used in the final release, in Medina's town square.
  • Several minor decorative changes were made, such as an extra peninsula jutting out towards (but not reaching) the Medina continent from the Porre continent, several trees being added in varying locations, a few fixes to some dirt paths, and a small inlet north of Medina being removed for whatever reason.

Guardia Forest

None shall pass!

Guardia Forest is fully functional in the prototype, and can be explored in its entirety. However, a group of four Blue Imps blocks the north exit to Guardia Castle, stating "You can't pass this point in this version."

Zenan Bridge

RPG bridges are so unreliable.

As mentioned above, the prototype Zenan Bridge is broken in 1000 AD, but more interestingly it's actually possible to enter it from the south, which grants a different view of the broken bridge not seen in the final.

Ultimately, this was probably deemed pointless, as it was still possible to reach Porre by ferry (which may well be why the ferry exists to begin with), and so it was patched up in the final.

The tiles for the south/west broken bridge still exist in the final, but are no longer used.

Guardia Prison

The Guardia Prison didn't undergo very many changes. The layout is identical, though there are a few pointless pre-opened chests here and there which were removed/closed in the final.

A few other oddities exist, however:

Creepy eyes! We are watching you.

At two points in the prison, strange "eyes in the darkness" can be seen poking out from the walls. The first instance is in the hallway with the guards that can be knocked out from behind, while the second set can be found in the closed-off cell with a couple chests in it. This is the same sprite seen behind the gate in Bekkler's Lab in the final, but there is one distinct difference...

Prototype Final
I see you! Blink blink.

...the eyes peer back and forth briefly before blinking, then disappearing, eventually reappearing and starting the whole cycle over again. In the final, all these strange eyes do is blink.

Got a nice view, at least.

Also of interest, although inaccessible, mixed in with the maps is this tower exterior. It looks similar to one in the final, but is much smaller, and with the exception of a large window is completely devoid of detail.

Heckran's Cave

Heckran's Cave was almost completely re-imagined for the final. For starters, the final uses a much brighter palette. However, the changes go far beyond that... It should be noted that the cave is completely devoid of events initially; there are no monsters, and none of the holes work. They can be re-activated using the following Pro Action Replay codes:

Prototype Final
Splish splash? Complex and cavey.

First off, the main hallway was made much more elaborate in the final. In the prototype, it's just a simple straightforward path with a small waterfall and stream.

Octoriders! They die just like any other monster.

Immediately after entering, you're greeted by a pair of Octoriders, who deliver a message and then attack. These enemies were left unused in the final.

The dialogue translates to "The Great Demon King led us in the battle against the humans attacking us, four hundred years ago. When our God is reborn, the humans will not matter......"

Who broke the Jinn Bottles? Same to you!

Yeah, that's pretty broken.

Further into the entry tunnel are a pair of broken Jinn Bottles, who also deliver a message (different from the Octoriders') before springing to life and attacking. These enemies, while present in the final, never actually appear broken, and the only monster dialogue spoken in the final is from the enemies at the very entrance.

This dialogue translates to "Four hundred years have passed since the Great Demon King brought about the birth of our God, Lavos. Our god's awakening is close at hand......"

Prototype Final
Hope you don't mind getting wet! High and dry. Mostly.

The main area is where the true differences lie, however, as the prototype version of Heckran's Cave is a large maze of currents and waterfalls. The currents aren't powerful enough to hinder movement, but it's the waterfalls you need to watch out for, as once you've dropped down one you can't get back up it. The entrance is in the upper-left corner, while the exit is in the upper-right. This room is entirely devoid of monsters.

In the final, this area was greatly simplified: instead of bothering with waterfalls, it's now just a straightforward run through some raised cliffs with a few added battles in between. This room was also effectively broken into two parts, with a quick dash through the water from the cave on the left, to the one in the center coming a little later.

The eyes have it!

More of those creepy eyes can be seen lurking in one of the lower tunnels. These ones, unlike the ones in the prison, constantly peer left and right, do not blink, and do not vanish. It seems the developers wanted to use this sprite for atmosphere a lot more frequently than what ended up happening.

Prototype Final
Holes! No more holes.

The sub-chambers of the cave weren't changed too much. The big difference is the lack of chests and the presence of several small holes which, if jumped into, all lead back to the waterfall in the entrance tunnel. These are necessary to escape, due to the presence of the one-way waterfalls in the main chamber.

One chest. Two chests. And one seriously messed up dialogue box.

Other things of note include that the dungeon contains only two treasure chests (as none of the side-rooms with holes contain any; these are merely traps with monsters in them in the prototype), and that while the holes are functional, the text displayed is incorrect despite the presence of a pointer.

Oddly enough, despite that it's clearly not intended to be used here, this text is actually unique! It translates to "It is said that in the western mountain's cave, the demon Heckran resides, ordered four hundred years ago by the Great Demon King to protect the land where our God, Lavos, slumbers."

Choras Ruins

Prototype Final
Choras was a monarchy? Well, not any more they aren't.

The ruins north of Choras underwent some heavy renovation, and palette differences aside, these changes apply to the ruins in both 1000 and 600 AD:

  • The most readily apparent change is the drastic difference in palette. The prototype uses the same palette as Guardia Castle of whatever era it's visited in, while the final gives them a much "colder" palette unique to the ruins, which gives off a much more foreboding air.
  • The layout is almost entirely different in the prototype. Unfortunately, with the exception of the entrance, none of the doors are connected to anything yet, so one can only speculate how all the pieces fit together. There are no scroll boundaries in place, however, so combined with a walk-through-walls code, one can explore the area entirely. Of particular interest are the presence of a throne and a dungeon, which give this early version of the ruins the look of an actual castle, and not just generic nondescript ruins. Ladder tiles not seen in the final game are also present in these proto-ruins.
  • In the prototype, you enter from the right staircase in the far upper left room. The final starts you in this same room, except the entrance is the nook in the bottom center of the room.
  • There are fewer treasure chests, they don't yet contain anything, and the sealed chests are missing.
  • The background music is "Underground Sewer" in the prototype (complete with water ambiance, as the water-free variation was not yet included), as opposed to "Silent Light" in the final.

West Cape

Prototype Final
You cannot mean to tell me this place continued to exist for 13,000 years. All right. Apparently it did.

As they're simply palette swaps of each other, it should come as no surprise that the 1000 AD West Cape underwent the same redesign as the 12,000 BC North Cape. The prototype version, however, lacks Toma's grave.

Forest Ruins Dungeon

In the final version, the Forest Ruins north of Medina are extremely enigmatic, and once you can finally access their secrets it generally comes as something of an anticlimax that all you get out of it is a choice between two treasure chests. However, it wasn't intended to be this way...


In the prototype, there are some extra graphics stored just off-screen, showing a large structure with a sealed door rising out of the blue blocks on the barrier-protected platform. And this door leads to a treasure-filled dungeon which was removed from the final game entirely.

Interestingly, the tiles for the structure are still present in the forest tileset in the final, but the structure itself has been deleted from the Forest Ruins map.


As for the interior of the structure, its design is perfectly in line with that of other Zeal architecture such as the Ocean Palace, Sun Palace, and Black Omen. An NPC in Enhasa in the final makes reference to a "palace in the north" where the "elemental weapons are sealed", then points you to the so-called "palace" on the world map, but unsealing it yields no such things. It's clear by looking at the prototype, however, that this is what he was referring to.

There isn't much else to say, however. The exits all work, and the chests all contain 500G, which would probably have been changed had this remained in the final.

The second and third rooms are on the same map, and both are loaded with more chests containing 500G. It doesn't matter which way you go, as both upper doors lead to the final room.

The final room was most likely going to have a boss battle, with some sort of "elemental weapons" being your reward for defeating it.
