The Legend of Zelda: Oracle of Ages

The Legend of Zelda: Oracle of Ages is a game that was released alongside The Legend of Zelda: Oracle of Seasons. The games interact with each other in a variety of ways.

Unused/Glitched Items
Like in Seasons, there are several glitched items mixed in with the normal ones. By changing RAM addresses (A button) or  (B button) to the following values, these items can be obtained. Interestingly, the items exclusive to this game are unfinished or glitch up in Seasons, and the same applies to items exclusive to the latter.

Unused Maps
Using the Zole editor, it is possible to find some unused maps.

Black Tower


There's an old version of the Black Tower in screen 86 of the "Present Underwater" map. The most surprising thing here is the door on the right side. If this map had been used, going north would have led to the Black Tower entrance while going west would have presumably lead back to Lynna City/Village. Where the doorway on the right would have gone to is anybody's guess.

Room


This little piece, not playable in the game, is almost empty. The table in the middle is the only object present.

Duplicate Rooms
There are a few rooms found in the game that are copies of various rooms found during normal gameplay. However, these rooms have different area IDs compared to their original counterparts found in normal gameplay and, as a result, have messed up tilesets.

Filler Screens
There are filler screens for most unreachable areas, for both Past and Present on the overworld and Past and Present underwater. Not all of them use the same "base" tiles.

These ones are used for unused screens outside the map bounds:

Rod of Seasons


Present in the game are some graphics of the Rod of Seasons from Oracle of Seasons. Obviously since the game doesn't use this item, they go unused. The palette of these graphics in the game are unknown, so the palette used here is the one from Seasons.

Goron Vase - Tileset


Some graphics of the Goron Vase from Seasons.

Underwater Cave Door


Graphics of the locked cave door from Seasons.

Farore


While Farore does appear in Ages inside the Maku Tree, she sits behind a counter and only faces downward. As such, the sprites of her facing left, right, and upward are not used.

Regional Differences
There are some minor differences between the different versions of the game.

Room in the Spirit's Grave
The bottom-left room of the Spirit's Grave is empty in the Japanese version, whereas there is a jar to push on a switch in the European and American ones. The main advantage of this change is that it teaches players early in the game that jars can be pushed, an element which may not seem obvious to them.

Strange Shelves
Three shelves in the mailman's house have a different design between versions.

In the Japanese and American versions, the three shelves on the top-right side of the room can be destroyed with the Power Bracelet or Level 2 sword, and react exactly like some pots. If you just destroy the bottom of a shelf, you will find a staircase that leads back to this same room; if you destroy the top and push the bottom, nothing will appear.

After destroying the shelves, it is possible to go north; doing so will take you to Rafton's house, albeit in a wall, and the only way out is to reset the game. This is probably why these shelves were altered in the European version.

Presentation Screen
The Japanese version has a "presentation screen" displayed before the Nintendo and Capcom logos, which noticeably refers to the game as its English title. This screen was removed from other versions.



Green Goron
The clairvoyant Goron of Rolling Ridge does not exist in the Japanese version, and was added to make collecting the Mermaid Keys easier.

Ending Screen
The message saying that the adventure continues in Seasons does not exist in the Japanese version.

Unobtainable Rings
Because the code to denote the player as using the Game Boy Advance is never activated, these rings cannot be obtained through normal means, although the last two are obtainable with a modified Ring Secret.
 * (Unknown) Ring (GBA Nature Ring)
 * (Unknown) Ring (GBA Time Ring)
 * GBA Nature ring
 * GBA Time ring

Advance Shop
The Advance Shop in Lynna Village still exists, but since the aforementioned code is never activated (for obvious reasons), it is inaccessible.

Blue Snake's removed script
The Blue Snake's script was removed because the 3DS doesn't feature the Game Link Cable.
