NOTE: All values in Tables are Hexadecimal unless noted otherwise.

Chip tiny.png The following article is a RAM map for The Legend of Zelda: Oracle of Seasons.

Bank 0 (C000 - CFFF)


TBD

RAM Size Purpose Note
C5C0 - C5FF Unappraised rings carried
C602 - C606 5 Bytes Player name
C616 - C61D 8 Bytes Rings owned
C61E - C61F 2 Bytes Deaths
C622 - C625 4 Bytes Time passed since power-on
C627 - C628 2 Bytes Rupees earned since file creation Value is represented in decimal.

Example: If the total earned rupee count is 8,473, the hexadecimal representation will be 0x8473.

When a rupee gain puts the value is pushed over 0x9999, the value is then set to 0x6363, the value will no longer change, and a flag (somewhere) is then set so that Vasu will give the Rupee Ring the next time he is spoken with.
C629 1 Byte Message Speed 0x00 - 0x04

Some higher values yield hilarious results such as a letter appearing once per few seconds.
C63A 1 Byte Current level bank
C63B 1 Byte Current Absolute Overworld Screen

OR

Current Relative Dungeon Screen		 On the overworld, all 256 map tiles are represented in order; left to right, top to bottom, 0x00 - 0xFF.


Inside a dungeon, only map tiles that are valid rooms are represented while empty map tiles are not counted; the only empty map tiles that are counted are the ones leading up to the first valid room in order, then from there, the value only increases with each valid room. Zelda OoS RAM C63B 01.png
C63C 1 Byte Current Absolute Dungeon Screen Unlike with C63B, all tiles on the dungeon map, including ones that do not represent a valid room, are counted in order; left to right, top to bottom, 0x00 - 0xFF.Zelda OoS RAM C63C 01.png
