An unofficial open-source client for osu! beatmaps, with the main focus on making practicing easier and customizing gameplay.

Runs on McEngine. The game code and Desktop version is available here.

Installation

How to install:

• Extract the zip file, then merge the contents with your microSD card (do not change any folder/file structures/names).
• If you are upgrading from an existing version, just overwrite everything except your cfg and Songs folder.
• Launch HBL via takeover or HBL via the NSP version (to get full RAM access, which this game requires), and start McOsu.

Notes:

• The game will give you a warning on the main menu if it doesn't have access to enough memory (< 1 GB).
• If you launch HBL via the Album applet, then only ~400 MB out of 4 GB are available, and some of that is already used up (at least during testing, this might not even be a problem anymore with newer Atmosphere/ReiNX/etc. versions).

User guide

Adding beatmaps/skins

You don't have to create any folder structures, everything is already prepared.

Follow the guide on extracting beatmaps/skins below, and simply put them into /switch/McOsu/Songs/ or /switch/McOsu/Skins/ on your microSD card. Default beatmaps are already included, so just follow their structure.

Troubleshoot/Notes

• If you get audio crackling after minimizing the game or going into sleep mode: To fix it, Go to Options > Audio > "Restart SoundEngine (fix crackling)".
• If you are playing beatmaps with a lot of sliders visible at the same time, and consistently getting less than 60 fps, improve performance by enabling Options > Skin > "Use slidergradient.png".
• If you get stuck at 0% loading forever, then the resource loader thread could not be created. Try restarting the game, HBL, and your system, in that order. This has only happened to me once, so it shouldn't be a problem.
• All speed changing mods are unavailable (DT/HT/DC/NC, Speed/BPM Multiplier, Timewarp) because the audio library does not support varying playback speed (yet).
