o!m2bms

Original Repo

Program that converts osu!mania maps to BMS maps. (currently only supports 2k to 8k)

Supports fully keysounded maps and bpm changes.

If you come across any Errors, please report them in the issues!

Installation

Written on Python 3.6+. You can download the required libraries by running:

pip install -r requirements.txt

Requires an instance of ffmpeg in your system PATH. Here's an ffmpeg installtion tutorial if you don't have it already. (To check it if works, type ffmpeg in your terminal, and it should not return an error)

Set the default output directory by running,

python om2bms_osz.py -sdo [OUTPUT DIRECTORY]

or go to default_outdir.ini and paste the path to a subdirectory in a BMS songfolder directory.

Running

Run

python om2bms_osz.py -i sample_osz_file.osz

to convert all 2k-8k files in sample_osz_file.osz and output them to [OUTPUT DIRECTORY]/sample_osz_file

To convert individual .osu files run

python om2bms_osu.py -i sample_osu_file.osu

Batch Converting

Run

python commandUI.py

To access the Command Line User Interface that allows some settings customisation and batch conversion of .osz files that are in the input folder (not compatible with single .osu files for now)

(I personally think always converting .osz files is best anyway)

To view help, run

python om2bms_osz.py -h

python om2bms_osu.py -h

Key Mapping

(note: I will make images for this section in the future | will also make the layouts customizable)

Lets define the columns like this = |1|2|3|4|5|6|7|8|.

If a column is used for the key count in question, it will have it's corresponding number inside it.

2k

|1| | | |5| | | | (so 1k + scratch with controller)

3k

| | | |4|5|6| | |

4k

| | |3|4| |6|7| |

5k

| |2|3|4|5|6| | |

6k

|1|2|3|4|5|6| | | (so 5k + scratch if controller)

To-do List

• Slider Velocity
• Difficulty calculation when converting
• Background Videos (Needs to find fix for offset)
• Persistent settings file for UI
• Support other keycounts then just 7k and 8k (Supports 2k - 8k)
• Improved background image resize/processing when converting
• Adapt to be used without command line, aka a general run function for the arguments (necessary for GUI and improving command line UI)
• Make GUI
• Drag-and-drop for GUI
• Change output file format from .bms to .bmson (will allow easier feature implementation). Not to be done for a while. Will require big rewrite.

Notes

• Tested with LR2
• Does not currently support SV changes
• Uses first timing point to estimate the first measure
• Assumes timing points are always the start of a new measure
• If there are >1 hitsounds played in one note, only plays the hitsound with the highest bit
