How to unlock the Ouranos Island Memories achievement in Sonic Frontiers - Definitive Guide

Ouranos Island's portals are found as you unlock the map and repaired when you've found enough portal gears for each one. They're most commonly found from the island's Guardians.

WARNING! This achievement can glitch. Highly recommend making a separate save right when arriving on the island.

First time around I repaired all the portals and didn't pop this achievement.

Thinking through what could've went wrong, there is one portal in the very southwest — 4-9. It is accessed via an island mystery. You solve this island mystery by dabbling with some tuning forks, and it opens a large circular door that you can go through.

Thing is is that you can access this area beyond just with boosting and jumping and don't have to do the island mystery. That is how I first got to the other side. Repaired the portal, finished the others and it didn't pop! Had a separate save at the beginning of Ouranos because I'm paranoid and went back again and this time did it properly, solving the island mystery first. It popped! Phew! I suspect the order of the two actually matters to the status.

These achievements require you to unlock all hyperspace stages on all four islands in the game. Each stage is unlocked the same way: collect one or two Portal Gears, and use them to unlock the stage from its pedestal in the open world. Once you complete all challenges to fully reveal your map, you can easily filter your map to Portals to see where all level portals are, and then fast travel to each one to unlock it. Note that you don't actually need to play levels for this, just open them.

As far as getting the Portal Gears, like the game teaches you, you get one guaranteed from each Guardian you beat. Unfortunately, they are island specific, so any extras you get don't carry over to the next island. You'll find though, that you get Portal Gears from breakable objects and from treasure spots too. This resulted in me always having more than enough Gears without even fighting all of the Guardians on each island. Guardians respawn all the time though, so you can just fight ones over again if you need more Gears to open levels up.
