This run starts from a savefile just after obtaining the Master Sword. For exact specifications, check the speedrun.com rules.
The Rupee route in this run hinges on a single factor: Once you get to Castle Town for the sidequests, you want to be at or below 200R so you can collect a 100R Chest. If you have more than 200R you will be unable to collect this and will need a backup instead (written in route)
