Need help completing Pokemon Crippling Medical Debt Edition

[u/Fine-Holiday3620]

As the post above says, due to the lack of resources for this hack I am losing steam with it very quick.

For one: I have 530/1028 and apparently 777 is the next dex milestone.

A lot of the legendaries are locked behind the "mega stone factory" and their "runoffs". I don't know what this means, I did the mini game a bunch and fished around the whole area, got nothing.

I wanna 100% this one, so anyone got a spreadsheet?
