XGP-save-extractor VS hephaistos

There is also a tool to port your save games from the xbox version to the steam version so I didnt loose any progress. https://github.com/Z1ni/XGP-save-extractor

To get your xbox save on steam you'd need to download the game through Game Pass as well as steam, boot game through Game Pass to make sure that cross saves show, then use this Game Pass save extractor to convert it to a steam save and should be good to go

There already seems to be a lot of ways to do the opposite (Game Pass -> Steam), like this python program.

I haven’t played Hades but found for another game the save system was very different between Game Pass and Steam versions. I found a Reddit thread with instructions on converting the save file. A quick search I found a GitHub project mentioning converting Hades here: https://github.com/Z1ni/XGP-save-extractor

Quick tip, you can install this in Desktop mode (it's an easy process) to make Hades fill the entire Steam Deck screen (without black bars on top and bottom). It looks even better that way.

You can run it in 16:10 using this https://github.com/nbusseneau/hephaistos

With this small mod from github

The game is locked in 16/9 aspect ratio though, I recommend you use Hephaistos if you’d like to run it without black bars on the computer’s internal display :)

Hephaistos mod author here. The issue happens because your monitor reports back too many supported resolution to the game, and the list of resolutions available gets trimmed to 9.

The game doesnt properly support the deck's resolution so it's letterboxed, but there is a mod to change that if it bothers you: https://github.com/nbusseneau/hephaistos

The repo has instructions for Linux/Steam Deck: https://github.com/nbusseneau/hephaistos
