O2Mania Tutorial

1. Download these first in order to smoothen the tutorial
2. First, install WinRAR
Install O2Client by first extracting it first by using WinRAR

After succesfully install o2Client, extract o2Mania.rar, and copy the folder to the folder where you install o2JamClient
Run o2Mania

Before you begin to play, you have to configure your graphic and sound card. To do this, click the red circle tab, and click the red arrow menu or simply press “F11”. After this it depends on your graphic card and audio card setting. This is my example. After you done, click the red circle or simply press “ENTER”. In order to test the audio, simply play any song. To learn how to play song, go to the O2Jam/DJMAX/BMS Tutorial. In order to test the video, play an animated song. Some DJMAX song is best to test it or you can try playing animated BMS song. Enjoy

7.1. Go o2Mania website
7.2. Go to o2mania forum
7.3. About program

O2Mania 1.4.2.(US version)
Download here
Basically this version of o2mania is the same as 1.2(above info). But this version has fixed some bugs(though I don’t know what bugs), able to play any VOS song, able to play some of broken sound song, all menu and option in English language.
Basically this version is more advanced and more complete than 1.2. The only downgrade is, sometimes when you try to open this version, sometimes it crashes. But its okay. Just rerun it.
To install it, just unpack it with WinRAR. IT IS RECOMMENDED that you save this version into different folder and not unpack it inside “e=games” folder. With this method you can still run 1.2. version as well as the new 1.4.2.US version.
NOTE : This program isn’t officially released by o2mania. This program is made by some people, so if you think this version is legit and official, its not.
NOTE 2 : The original RAR file doesn’t contain d3dx9.dll. Well, this one is not(cause I already download it and pack it into one). IF somehow after unpacking, and when you try to run the program, and it still lack of some .dll file, do this : Open your browser, go to, type in Search box “download xxx.dll”, and you should find the file easily
NOTE 3 : Since it can play previously broken sound song, then new icon will appear next to song info as (1.4)

    Where I can download VOS song? Can you give me the link? I even didn’t know what is VOS Song, and how it can be played on O2Mania 1.4.2.

  2. zackoy says:

    Bot playing very good in O2Mania 1.2.0, but in O2Mania 1.4.2 the bot is not good enough for playing some impossible song like [SHD]Xepher (Lv 1155). I was think that O2Mania 1.4.2 can play that song full combo, but it doesn’t. So in my opinion, O2Mania 1.2.0 is better than O2Mania 1.4.2.

    • Nene says:

      @Zackoy : Is it? I haven’t tested it yet. But still o2mania ver 1.4 can play some song that is when played on 1.2 version, the song doesn’t have sound. You can keep both version anyway. Just copy-paste to different folder. As for VOS song, VOS is an old o2jam like offline game. Try searching it by google

  3. zackoy says:

    There is one more thing the different between O2Mania 1.4.2 and O2Mania 1.2.0, that is the judgement line. Normal in O2Mania 1.4.2 is like Hard in O2Mania 1.2.0.
