Side Note: If anyone is wondering, the name seems to be from Nokia's Symbian Anna and Symbian Belle version, as it seems these icons are inspired by the default icons from those OS versions (another one is Beluk Icons from sikebo, and theres many others). RIP Symbian.

The app drawer icon triforce is the Ocarina of Time icon from Beluk.
I don't even have this game.
You can use Beluk to fill the gaps although it isn't as good.

BELUK ICON PACK is probably my favorite.
Beluki is very similar and has 3500+ icons. Though if you have none missing, that's academic. I have a few of that author's packs, all very high quality and equally comprehensive. Particularly recommend Immaterialis and Retrorika as distinctive.
It's called Beluk. I quite like it, and it's got over 3500 icons.
