Additional Information
Unused Maps
The game has space for 1104 map IDs, yet 214 of those are empty (which are almost 20%). This might imply that parts were removed or not implemented at all.
The unused maps that are left in the game are one test level and 6 rooms.
Collision Test Level, ID: 6
This level features collisions tiles seemingly placed randomly and the final boss of the game with an incorrect AI script (scripts have hardcoded addresses) and will thus behave broken.
Tower rooms, ID: 0xBA, 0xBB, 0xBC
Though all three maps are connect there is no exit that leads to the first part (left).
The exit of the left room (0xBA) leads to 0xB3 which only has one exit leading to 0xB7, the tower that leads to a single chest
None of the chest contain anything, they can't be opened as there is no chest information for this map ID.
Unknown Shop, ID: 0x3F1, 0x3FF
Though these rooms have working entrances and exits which can be enabled by setting certain event flags they normally can't be accessed and no NPC are implemented for these rooms either.
The outside has something that looks like a boot kicking a hat over a blinking orb.
Boss - Dark Gaia, ID: 0x280
A large part of the map is never used, only the part in the red box is ever seen in-game.

Old Chest Design
This design can also be seen in the Terranigma beta demo.
The tile set of 0x3AB, 0x3AC and 0x3AD still have this design in them, but none of these maps have any chests.
Unused/Unreachable Exits
These exits are usually not accessible via normal means, there are few in the game.
Ark's Room, ID: 0xF
Directly in the first room of the game there is an exit that would lead you directly before the final boss of the final tower (ID: 0x122).
5th Tower Entrance, ID: 0x11C
This map has two exits in the top left area of the map, one leading to map ID 0x11E (2nd Floor of the 5th Tower), the other to the same map ID 0x11C at 256.896.
Castle, ID 0x0426
This leads to the chest room mentioned below.
During a certain event going up to the wall will trigger a message telling you not to go this way, implying this was fully implemented but apparently later removed.
It seems they forgot to update the script reflecting the change.
Castle, ID 0x421
This exit is behind a chest and is also within a wall, it leads to map ID 0x424. (Usually you get to map ID 0x424 from the exit in 0x429)
Debug Functions
There are a few debug functions left in the game that normally can't be access by normal means.
Debug
The script offers you three options:
- Port to plane map ID
- Jump to ending
- Gain XP to reach level 34 and some weapons and armor as well as 1 of each magic ring
Debug Port - 1
This script can port you directly to three different locations:
- "French Village"
- "Amazon Cave"
- "French City" (the script automatically sets the event flags)
Debug Port - 2
This script can port you directly to four different locations:
- "Dev. Rm" (0x32B)
- "Mole" (0x57)
- "Chicken" (0x32F)
- "Eating" (0xBD)
Debug Port - 3
This script can port you directly to four different locations:
- "Sqrl Vil" (0x38E)
- "Sqrl C" (0x399)
- "NY Town" (0x356)
- "NY City" (0x36F)
Event Flags
This script allows you to set event flags counted in bits.
Sound Test
This allows you to play sound effects and music tracks from the game.
This only works in the Japanese version as in the other versions the titles have been stubbed and cause a crash.
Secrets and other oddities
Talking Plant, ID: 0x328
It is actually possible to "talk" to the plant, which says something different in the German version.

"Hello (slang)! I am the [script] writer of the German game."

Pre-release Versions
As recently discovered (27th July 2015) [1] some kind of beta version seems to exist.
This versions has a lot of differences between the final version of the game.
- Different chest graphic
- Elder's room has vase and something else lying on the ground
- Green decoration around the UI
- Ring menu is an overlay UI selection
- A very different intro, showing an hatching egg
- Different sound effects
- Tower has not yet the climbing chains but you can climb it
- Recreation room doesn't exist yet, a different animation is shown
Further proof for this is some French magazine which previewed Terranigma had three screenshots from the same or similar version.
No pre-release/beta dumps for Terranigma seem to exist.
