Reverse Bottle Adventure
Introduction
Reverse Bottle Adventure is the reverse of Bottle Adventure. Instead of writing a value to the B button based on the item value on Child Link's II Button and a certain memory address, we are writing a value to a specific memory address, based on the item on Link's II Button and the item value that the B button is changed to.
The value we are writing depends upon which item on B, or modifier, is used.
The memory address affected depends upon the item on the II Button.
The new value is written when the item on B changes to a valid modifier item.
Modifiers
Here's the list of modifiers that can be used in RBA. These are the items we can put on B that will check the value of the II Button and then update the corresponding memory address.
| RBA modifiers |
| modifier | decimal | binary |
|
Empty bottle | 20 | 0001 0100 |
|
Fairy | 24 | 0001 1000 |
|
Fish | 25 | 0001 1001 |
|
Blue fire | 28 | 0001 1100 |
|
Bug | 29 | 0001 1101 |
As Bottles are the only items which use pointers (which lets Bottle Adventure work in the first place) we are stuck with only five modifiers. These restrictions mean that the only thing RBA can do is replace a memory address (determined by your item on the II Button) with the value 20, 24, 25, 28, or 29.
That said, because of the way the game stores information, this leads to a lot of interesting feats. Let us begin:
Item Screen
As the lowest value item is Deku Stick (value: 0), this is where we begin. Having Items from the Item subscreen on the II Button while changing the value of your B bottle will result in new bottles to your inventory. Example: You have Farore's Wind on your II button. You catch a Fairy in your B bottle. Now if you check your inventory, your Lens of Truth slot will be overwritten with a bottled Fairy! This may seem useless at first due to the 21 Bottles glitch doing the same thing, but it is worth noting that you can also replace the Ice and Light Arrow slots (which are normally impossible to replace - Fire Arrow remains the only item on the Item Screen that can never become a bottle), and certain slots for items that you may not have yet. (e.g. using Lens of Truth to put a Bottle in the Megaton Hammer slot).
| Item Slots |
| item on the II Button | item slot replaced |
|
Deku Stick | Deku Stick |
|
Deku Nut | Deku Nut |
|
Bombs | Bombs |
|
Fairy Bow | Fairy Bow |
|
Fire Arrow † | Fire Arrow |
|
Din's Fire | Din's Fire |
|
Fairy Slingshot | Fairy Slingshot |
|
Fairy Ocarina † | Fairy Ocarina/Ocarina of Time |
|
Ocarina of Time † | Bombchus |
|
Bombchus | Hookshot/Longshot |
|
Hookshot | Ice Arrow |
|
Longshot | Farore's Wind |
|
Ice Arrow | Boomerang |
|
Farore's Wind | Lens of Truth |
|
Boomerang | Magic Beans |
|
Lens of Truth | Megaton Hammer |
|
Magic Beans | Light Arrow |
|
Megaton Hammer | Nayru's Love |
|
Light Arrow | Bottle #1 |
|
Nayru's Love | Bottle #2 |
|
Empty Bottle | Bottle #3 |
|
Red Potion | Bottle #4 |
|
Green Potion | Adult Trade Items |
|
Blue Potion | Child Trade Items |
|
Bottled Fairy | Iron Boots †† |
|
Bottled Fish | Hover Boots †† |
† - Unequippable to the II Button.
†† - You can not RBA over Iron/Hover Boots if you have them in your item menu.
The list starts off "normally" but becomes staggered. This is because some slots (Ocarina slot, Hookshot slot) can hold multiple items. If you replace a slot that is only usable as a certain Link (example: replace Child Trade Items slot with a bottle), it becomes equippable with the improper Link. The item slot is irrelevant.
After Bottled Fish, the game has cycled the inventory once. Now it goes through it again, with the AMOUNT you have of each item.
| Item Amounts |
| item on the II button | item amount updated |
|
Lonlon Milk (full) | Deku Stick amount |
|
Bottled Letter | Deku Nut amount |
|
Blue Fire | Bomb amount |
|
Bottled Bug | Arrow amount |
|
Big Poe | Fire Arrow amount † |
|
Lonlon Milk (half) | Din's Fire amount † |
|
Poe | Deku Seed amount |
|
Weird Egg | Ocarina amount † |
|
Cucco | Bombchu amount |
|
Zelda's Letter | Hookshot/Longshot amount † |
|
Keaton Mask | Ice Arrow amount † |
|
Skull Mask | Farore's Wind amount † |
|
Spooky Mask | Boomerang amount † |
|
Bunny Hood | Lens of Truth amount † |
|
Goron Mask | Magic Beans amount |
|
Zora Mask | Magic Beans popularity †† |
† - Unused item amount
†† - This is how many Magic Beans you've ever bought from the Bean seller in Zora's River. For example, if the value is set to 6, he will charge you 70 rupees for a bean. Any values higher than 9 cause him to stop selling beans.
Using RBA with these items on the II Button will simply write the value of your bottled item on B as the new amount of the item on the right column. Example - catch a fairy in your B bottle while a bottled Bug is on the II Button and you will have 24 Arrows.
Gear Screen: Right-Side
Alright. The equipment is handled differently - several items are stored within the same byte of data, they merely have on/off switches to determine if you have them or not. This way the game can save space by storing information like which tunics & boots you have in one 8-digit binary value.
An example: Lets say the value of the Tunics & Boots byte is 0001 0111. What does that mean? Well, if you convert it into decimal, you get 23. 23 is 1+2+4+16. By using RBA, you can rewrite this value to the value of one of the modifiers above.
| Mask of Truth on the II Button |
| what item | binary value | decimal value |
|
Kokiri Tunic | 0000 0001 | 1 |
|
Goron Tunic | 0000 0010 | 2 |
|
Zora Tunic | 0000 0100 | 4 |
|
Kokiri Boots | 0001 0000 | 16 |
|
Iron Boots | 0010 0000 | 32 |
|
Hover Boots | 0100 0000 | 64 |
If you delete your Kokiri Tunic, then have a Like-Like eat your remaining Tunic, the game puts the Kokiri Tunic back on you, despite you not having it. In your inventory the empty slot where the Kokiri Tunic would go will be selected, sort of like how if you skip the Kokiri Sword, become an adult, then go back in time, you will be wielding the Kokiri Sword, despite having never gotten it, and it not being in your inventory.
The Boots bits works in a different manner as they've changed how the boots are used in the 3DS version. You can read more about it on the Boots Oddities page.
Now the swords & shields byte:
| Gerudo Mask on the II Button |
| what item | binary value | decimal value |
|
Kokiri Sword | 0000 0001 | 1 |
|
Master Sword | 0000 0010 | 2 |
|
Biggoron Sword | 0000 0100 | 4 |
|
Giant's Knife † | 0000 0100 | 4 |
|
Giant's Knife (broken) | 0000 1100 | 12 |
|
"Broken" †† | 0000 1000 | 8 |
|
Deku shield | 0001 0000 | 16 |
|
Hylian shield | 0010 0000 | 32 |
|
Mirror shield | 0100 0000 | 64 |
† - Giant's Knife and Biggoron Sword share the same value. There is a different variable in place elsewhere to determine which one it is.
†† - "Broken" is the trigger if the Giant's Knife is broken or not. Using RBA you can actually get the "Broken" trigger to be on without having the third sword. This causes there to be the image of the broken sword in your inventory, but the cursor moves right past it when you try to select it.
Gear Screen: Left-Side
Left-Side Gear Screen is simple. Each bit represents something you either have or do not have.

† This works in conjunction with your Bullet Bag. See the chart further down to see what you can do with this.
†† Just to save you the time, yes this upgrade is impossible -- the only way would be Halfmilk RBA with the Pocket Egg, but that means the value must be set to 26, and there is no way to do that to this value.
††† You can hold up to 255 (if you buy more it wraps around to 0), but if you have over 128 and try to use one, it changes to 0. Also, the icons become screwed up once you get over 99. This upgrade is impossible to get.
Well, those are the RBA charts for the left-side equipment. The left-side equipment is pretty complicated with the way the values can relate. There are a few other things you can do by mixing two values that take up the same slot, in order to get something new. You can mix your child Bullet Bag with Pocket Egg RBA to get other items on that slot. Here's the chart for that.
| Bullet Bag Slot - Mix Chart |
| Pocket Cucco RBA value | Pocket Egg RBA value | item | effect |
|
xxxx xxx0 | 01xx xxxx | Bullet Bag (30) | works normally |
|
xxxx xxx0 | 10xx xxxx | Bullet Bag (40) | works normally |

|

This one isn't very interesting, besides the very low capacity slingshot.
Something more interesting are the special colored gauntlets. This uses Pocket Egg RBA mixed with the strength upgrades.

All colored gauntlets have the strength of Golden Gauntlets (can lift all objects).
This is pretty simple to do, just update the Pocket Egg RBA value with any odd number (something that will end in a 1 in binary).
| Odd Mushroom on the II Button |
| what item | binary value | decimal value |
|
Forest Medallion | 0000 0001 | 1 |
|
Fire Medallion | 0000 0010 | 2 |

|
Minuet of Forest | 0100 0000 | 64 |
|
Bolero of Fire | 1000 0000 | 128 |
It is possible to RBA Odd Mushroom as Child.
It is worth noting using RBA can get you the Shadow and Spirit Medallions, which lead to Light Arrows and the Rainbow Bridge cutscene. In old routes, this was used to skip all adult dungeons in any%.

|
Gold Skultula † | 1000 0000 | 128 |
† Gold Skulltula count is stored somewhere else; having its bit set to 1 simply shows your count as opposed to not showing it (back when you first start your file, it doesn't show up).
| Broken Goron Sword on II |
| what item | binary value | decimal value |
|
0 heart pieces | 0000 xxxx | 0 |
|
1 heart piece | 0001 xxxx | 16 |
|
2 heart pieces | 0010 xxxx | 32 |
|
3 heart pieces | 0011 xxxx | 48 |
Picking up a heart piece adds 16 to the previous value. The last 4 binary digits do nothing.
Dungeon Items
Dungeon items are the dungeon-specific items, such as the Compass or the Map. You can use RBA to delete or create them. All of the dungeons hold the data for these items the same way.
| Dungeon Item Values |
| what item | binary value | decimal value |
|
Big Key | 0000 0001 | 1 |
|
Compass | 0000 0010 | 2 |
|
Dungeon Map | 0000 0100 | 4 |
Each dungeon has its own byte for the dungeon items. Here are the items you need to put on II:
| Dungeon Item RBA (adult-only) |
| item on c-right | what dungeon | memory address |
|
Perscription | Great Deku Tree | 11A678 |
|
Eyeball Frog | Dodongo's Cavern | 11A679 |
|
Eyedrops | Jabu-Jabu's Belly | 11A67A |
|
Claim Check | Forest Temple | 11A67B |
|
Fairy Bow+Fire Arrow | Fire Temple | 11A67C |
|
Fairy Bow+Ice Arrow | Water Temple | 11A67D |

|
Giant's Knife † | Ice Cavern | 11A681 |
|
Deku Shield † | Ganon's Castle | 11A682 |
† Unequippable to II.
At this time, the Claim Check has the highest item value of all items that are known to be equippable to the II button. The following are predicted outcomes based on the findings done in the N64 version.
| Small Key Amount |
| item on c-right | what dungeon |
| BulletBag (40) | Deku Tree |
| BulletBag (50) | Dodongo's Cavern |
| Quiver (30) | Jabu Jabu's Belly |
| Quiver (40) | Forest Temple |
| Quiver (50) | Fire Temple |
| Bomb Bag (20) | Water Temple |
| Bomb Bag (30) | Spirit Temple |
| Bomb Bag (40) | Shadow Temple |
| Goron's Bracelet | Bottom of the Well |
| Silver Gauntlets | Ice Cavern |
| Golden Gauntlets | Ganon's Castle |
| Silver Scale | Gerudo Training Ground |
| Golden Scale | Gerudo Fortress † |
In the 64 version of Ocarina, it's possible to collect Bomb Bag 20 on a C button due to an Upgrade Oddity. It is not known if it's possible to put this item on II at this time.
† Keys only work on the appropriate cells.
