Arrow vortex

ArrowVortex can be used to create or edit stepfiles for various rhythm games, such as DDR, ITG, PIU, Stepmania, and Osu. It started out as a hobby project for me, aiming to create a modern stepfile editor inspired by the designs of both DDReamStudio and the Stepmania editor. Through my own experiences as a stepfile artist and the feedback of many other players and stepfile artists in the rhythm game community, ArrowVortex has grown into a powerful editor that offers many nifty features to make stepfile editing more convenient, simple, and fun.

Some of the features that ArrowVortex has to offer include:

– Automatic BPM/offset detection
– Automatic stream generation
– Automatic difficulty estimation
– Full editing history with undo/redo
– Dancing Bot: plays your charts using two virtual feet
– Powerful editing tools: copy/paste/mirror/expand/compress/etc.
– Scrollable minimap with chart preview, for easy navigation
– Built-in Ogg Vorbis conversion for MP3/WAV files
– Fully customizable shortcuts
– Customizable game styles and noteskins

SM/lua + ITG/xml script templates

So I’ve been going at it for a while now, and with (lots of) help from Fietsemaker and Thumbsy I’ve been getting the hang of making scripted files in lua for StepMania and xml for In The Groove now.

I’ve uploaded some templates for typical thing one might want to do to add some spark to their simfiles. These templates by NO means dummy-proof, and will require at least sóme feeling for coding to make the most of it.

In the Template folder there are some topics with example scripts inside them. The .lua files are commented and explained. The .xml files are there to show how to do the same thing in xml. Translating from one to the other will take time, patience and practice but at least there are some examples.

Make sure to read the README files and name all files correctly, as well as paying attention to the song folder layout.

I’ll try to update the templates periodically and add new examples from time to time.

Muchos creditos to Fietsemaker and his seemingly infinite patience!
Disclaimer: I am by no means a great programmer, and though the provided templates all work, I’m sure there would have been a MUCH cleaner or better way to accomplish the same results.

Download manager

I made a download manager for Stepmania. It allows you to easily manage packs from different sources.
Current implemented sources are:
– R21 Dropbox
– NL Community host

The software allows you to make lists with packs. It will download and delete according to the selection.
If you find any bugs, leave a message!

One of the cool features is making lists, say if you are playing online you can prepare a list, have a friend install it. That way you can be sure you have the same songs available. You can even configure your system to use “Open With” for the application.

Notice: This does work on java, so make sure you have it installed:


– Added NL community host
– Removed SMO host (for now)
– Auto updater
– Moved ini to appdata

– Switched from Swing to JavaFX
– Integrated new design (thx Behy)
– Added ITG dropbox
– Cache loaded packs (reload by clicking: check for new packs)

– Cleaned code
– Fixed list not updating bugs
– Added new provider, all the ddrnl packs should be on there now :D
