osu3DS

osu!3ds is a homebrew rhythm game, an attempt to port osu! to the Nintendo 3DS.

Currently this is not for the average user and its still very, WIP as theres no beatmap parsing basically and no audio output.

Building

Take your beatmap.osu file and remove everything except for the stuff below [HitObjects] (and also remove [HitObjects] its self).
Save this file and call it BeatmapData.csv and move it to where you compiled that C# at.
Open a Command Prompt (or equivalent) and CD to where you compiled the C# code at.
Run the following command <CompiledFileName> > BeatmapCode.txt (replace <CompiledFileName> with the file name of the EXE name).

Assuming you have devkitPro already installed:

Clone this repo somewhere https://github.com/Cyuubi/osu-3DS
Edit main.c in the source folder and replace line // Beatmap C data with the contents of BeatmapCode.txt.
Create 2 folders inside the cloned osu-3DS folder called romfs, and inside the romfs folder make a folder inside it called default, this is where the skin will be at.
Copy an entire skin that contains at least these 4 files approachcircle.png, cursor.png, hitcircle.png and hitcircleoverlay.png to the default folder inside the romfs folder.
Open Command Prompt (or equivalent) and CD to the cloned repo and run make there should be no errors at all.
Copy osu-3DS.3dsx to your 3DS (which has homebrew) SD card or run this with Citra.
