Guide: Installing McOsu on Linux with Steam Proton

This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.

1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."

Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.

Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.

2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.

3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.

4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.

What is McOsu? Features and Description

A free open-source circle-clicking rhythm game practice client for osu! beatmaps with Virtual Reality support. McOsu is developed separately from and has no direct affiliation with osu! or ppy Pty Ltd.

McOsu is developed separately from and has no direct affiliation with osu! or ppy Pty Ltd.
McOsu is NOT osu!

A free open-source circle-clicking rhythm game client for osu! beatmaps, with the main focus on making practicing easier and customizing gameplay.

It is primarily a practice client for getting better at the official game by having tools at your disposal that osu! does not provide for some reason, it's not supposed to be a perfect copy of osu!, or to otherwise profit with a free game from a free game (what).

If you have never played osu! before, then I do not recommend using this client (except for VR players of course), as there are no gameplay tutorials in here (just google "osu!" and play the official game which is a lot more polished).

Features:

Unlimited Customizability (Options, Console Commands via SHIFT + F1)
If something is not customizable, ask and it will usually be made so
Beatmap Overrides (Approach Rate, Circle Size, Overall Difficulty)
Speed/BPM Slider
Scrubbing and Quicksave/load (SHIFT and F6/F7, rebindable, jump to any point in time of a beatmap)
Experimental Mods (Wobble, Jigsaw, First Person, Playfield Flipping, Reverse Sliders, etc.)
Change mods and options while playing (F1 and CTRL + O)
Built-in pp counter (live stats overlay + ranking screen)
Compatible with 99% of all osu! skins
VR gamemode

Beatmaps

Play any osu!standard beatmap by installing osu!, creating an account there and downloading beatmaps from the "Beatmaps" tab on the same page + importing them into osu!. After they are imported, you can close osu! (to force save the database) and start McOsu
McOsu will load your beatmaps directly from the default osu! installation path, although custom paths are also possible
You can use McOsu without installing osu!, a guide on manual beatmap management is available in the Steam Community Guides section for McOsu

Holodance VS McOsu

While Holodance is focused on providing a full VR rhythm game experience with osu! beatmap compatibility as a sideproject, McOsu tries to bring pure osu! gameplay into Virtual Reality while staying as close to the original as possible.

osu! VS McOsu

The intention of this game is neither to replace peppy's client, nor to split the community.

As a wise man once said, "plz enjoy game".

Please note that while McOsu is always a work-in-progress, gameplay is very solid in both VR and Desktop mode.
If you want, you can help out with McOsu development on Github, or just take a look at the code, as this is an open-source project.
