There's a lot of stuff linked together between Dark Link and Link, I hacked the value of what Item Dark Link has in his hands and manipulated him to put away his Sword, but because I hacked the value of what Item he was holding, he pulled out the Item that I assigned him to have instead and whenever he broke the Giant's Knife and used a Bottled Item, it assigned it to the B Button.
Been working on a compilation video for weeks of everything Dark Link and Link share mechanically together.
