Adult Reset

Information

Going through time without a Master Sword in your inventory will activate Adult Reset — which is to say the game will assume that this is your first time becoming Adult Link. Since Adult Link cannot use items like Boomerang, Adult Link's equipment and C buttons defaults to to a specific set of items.

This includes:

• Deku Nuts on C-Left (only if you have them, else blank)
• Bombs on C-Down
• Ocarina of Time on C-Right (only if you have it, else blank)
• Master Sword in inventory, equipped and on B
• Hylian Shield equipped (only if you have it)
• Kokiri Tunic equipped
• Kokiri Boots equipped

As Bombs are always equipped regardless, it's possible to skip obtaining a bombs properly. By using Cojiro RBA you can obtain a bomb bag, allowing you to collect bombs and use them as long as they are equipped to a C button.

As the light arrow cutscene acts as a BA trigger, this counts as going through time and has all the properties of normal BA, including the ability to Adult Reset. This is used to get the MS back on a 1.0 save file during an any% run.

Notes & other info

Being swordless and going back in time also seems to trigger Adult Reset, despite having the MS in the inventory. This was found by unreal, and should be looked into more carefully.

It should be noted that due to Adult Reset, Zora Mask BA can never avoid having the second least significant bit flagged while putting an item on B.
