Different combinations of these values applied to one of these three addresses will result in having different combinations of <strong>Big Keys, Compasses, or Dungeon Maps</strong> respectively.<br /><br />
After each significant value, the amount of combinations of values until the next significant value are the amount of combinations before the last significant value multiplied by 2 and adding 1. There are therefore <code>0x7F</code> combinations after the value <code>0x80</code> which puts the byte's value at <code>0xFF</code> thus making it the perfect amount of space to describe 9 things and all their combinations including the possibility of nothing (<code>0x00</code>).<br /><br />
'''Example''': If you wanted to have one of these items in only Levels 1, 3, and 6, you would add the values for those levels together [<code>0x01 + 0x08 + 0x20</code>], the result of which is <code>0x29</code>, and apply that value to the corresponding address.<br />If you want one of these items in every level, that's [<code>0x01 + 0x02 + 0x04 + 0x08 + 0x10 + 0x20 + 0x40 + 0x80</code>] which is <code>0xFF</code>.-->

Each essence has a corresponding value associated with it, each value being double the value of the previous one, and the value of this address will be the sum of all the essences collected up to <code>0xFF</code>.
 
 
 
'''Example''': If the value of this address is <code>0x1F</code>, the collected essences will be <u>Fertile Soil</u>, <u>Gift of Time</u>, <u>Bright Sun</u>, <u>Soothing Rain</u>, and <u>Nurturing Warmth</u> (5/8 essences in sequence).
 
 
 
Any value in this address is valid, but many of them will not normally be used unless essences are collected out of sequence. Assuming all essences are collected in sequence, the value will progress as follows:
 
 
<center><big>'''<code>0x00</code>'''</big> -> <big>'''<code>0x01</code>'''</big> -> <big>'''<code>0x03</code>'''</big> -> <big>'''<code>0x07</code>'''</big> -> <big>'''<code>0x0F</code>'''</big> -> <big>'''<code>0x1F</code>'''</big> -> <big>'''<code>0x3F</code>'''</big> -> <big>'''<code>0x7F</code>'''</big> -> <big>'''<code>0xFF</code>'''</big></center>

* <big>'''<code>0x04</code>'''</big>: Saved the World — <u>Victory Ring</u><br /><br />
 
Based on what events have occurred, the above values get added to this address. Obtaining each corresponding ring from Vasu then adds the corresponding value multiplied by 0x10 to this address.
 
 
 
'''Example''': If the value is <code>0x03</code>, the player has collected 10,000 rupees and slayed 1,000 Monsters <code>[0x02 + 0x01]</code>. In this scenario, after the Rupee Ring is received, the value would then be <code>0x23</code> <code>[0x03 + (0x02 * 0x10)]</code>, and then when the Slayers Ring is received, the value is <code>0x33</code> <code>[0x23 + (0x01 * 0x10)]</code>.<br /><br />

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 Length Purpose Note
$C5C0 - $C5FF 64 Bytes Unappraised rings carried
$C602 - $C606 5 Bytes Player name
$C616 - $C61D 8 Bytes Rings owned
$C61E - $C61F 2 Bytes Deaths
$C620 - $C621 2 Bytes Enemies killed since file creation When total killed enemies reaches 0x3E8, 0x01 is added to $C6CA to set a flag for Vasu to give the Slayer's Ring, and this no longer increments when killing enemies.
$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 pushes the value over 0x9999, the value is then set to 0x6363, the value will no longer change, and $C6CA is then incremented by 0x02 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

$C691 1 Byte Inventory Slot 16



RAM Length Purpose Note
$C6A2 1 Byte Current Hearts
$C6A3 1 Byte Max Hearts
$C6A5 - $C6A6 2 Bytes Rupees Value is represented in decimal.

Example: If the total rupee count is 639, the hexadecimal representation will be 0x0639.
$C6A7 - $C6A8 2 Bytes Ore Chunks
$C6A9 1 Byte Shield level
$C6AA 1 Byte Current Bombs
$C6AC 1 Byte Sword level
$C6B1 1 Byte Boomerang level
$C6B3 1 Byte Slingshot level
$C6B4 1 Byte Roc's feather level
$C6B5 1 Byte Ember Seeds
$C6B6 1 Byte Scent Seeds
$C6B7 1 Byte Pegasus Seeds
$C6B8 1 Byte Gale Seeds
$C6B9 1 Byte Mystery Seeds
$C6BA 1 Byte Gasha Seeds
$C6BB 1 Byte Essences
  • 0x01: Fertile Soil
  • 0x02: Gift of Time
  • 0x04: Bright Sun
  • 0x08: Soothing Rain
  • 0x10: Nurturing Warmth
  • 0x20: Blowing Wind
  • 0x40: Seed of Life
  • 0x80: Changing Seasons

Each essence has a corresponding value associated with it, each value being double the value of the previous one, and the value of this address will be the sum of all the essences collected up to 0xFF.


Example: If the value of this address is 0x1F, the collected essences will be Fertile Soil, Gift of Time, Bright Sun, Soothing Rain, and Nurturing Warmth (5/8 essences in sequence).


Any value in this address is valid, but many of them will not normally be used unless essences are collected out of sequence. Assuming all essences are collected in sequence, the value will progress as follows:


0x00 -> 0x01 -> 0x03 -> 0x07 -> 0x0F -> 0x1F -> 0x3F -> 0x7F -> 0xFF


$C6CA 1 Byte Vasu Ring Flags
  • 0x01: Slayed 1,000 Monsters — Slayer's Ring
  • 0x02: Collected 10,000 Rupees — Rupee Ring
  • 0x04: Saved the World — Victory Ring

Based on what events have occurred, the above values get added to this address. Obtaining each corresponding ring from Vasu then adds the corresponding value multiplied by 0x10 to this address.


Example: If the value is 0x03, the player has collected 10,000 rupees and slayed 1,000 Monsters [0x02 + 0x01]. In this scenario, after the Rupee Ring is received, the value would then be 0x23 [0x03 + (0x02 * 0x10)], and then when the Slayers Ring is received, the value is 0x33 [0x23 + (0x01 * 0x10)].
