A long lost O2Jam X2 client that you won't find elsewhere.
Typically, you will only find emulator but this one include the actual client as well.

Join the discussion here for more details.

How to run the game
1. Run GameEmu.exe and press the button on top right.

2. Once you enter the game, refer following image to pass thru the lobby.

3. And once you're in the lobby, you will play the game by abusing the mission feature instead creating room, because emulator isn't capable enough to simulating the room creation, refer following image.


Workaround / Fixes
It requires bit of efforts to make it work under Windows 8 or newer, please do following steps to workaround:

1. In case you're running in Windows 7 or lower and encounter performance issue, delete ddraw.dll inside the folder client.

2. And for Windows 8 or newer and still having lag issue, try to use different DirectDraw wrapper, here's few of them, refer to README.txt for more information.
3. MSWINSCK.OCX not found / registered? try to run regsvr32 MSWINSCK.OCX in your O2Jam X2 directory as administrator.

4. If GameEmu.exe somehow won't show up, you have to use compatibility settings, now this one is a bit a mess since it varies for each systems, sometimes you need to change this throughout windows update, even with windows update turned off, you may still encounter inconsistent behavior.

To customize the compatibility settings, right click GameEmu.exe -> Properties -> Compatibility. Try to play around, especially Compatibility Mode which should be Windows XP SP3 or lower. Here's my latest settings



How to add more songs
This one is not tested and not guaranteed succeed. First thing first, let's have a look o2jam music works. O2Jam make a use a list file called OJNList.dat inside Image folder to list available songs in the game, in other words, the game does not scan music files directly. There's slight format difference between client versions throughout the patch and release versions.

X2 uses a newer OJNList format than Chinese client (which is common client) but older than nowcom client (latest one). OJNList of nowcom client contain Game Key Mode metadata like 3K, 5K or 7K, as the result, this will render your Chinese client OJNList useless.

Use my tool here to generate OJNList with nowcom format, but it might fail as it contains Game Key Mode metadata. Help me contribute this open source tool to support this format by making Pull Request / Issue https://github.com/SirusDoma/O2MusicList here in github!

Steps:
1. Place your music files (OJN and OJM) in "Music" folder.
2. Generate OJNList with my tool here, again, join this thread for more information
3. Save it in Image folder as X2OJNList.dat
