I don't have GLunia, but I tried it with KTest.
The launcher will run, which is really nice since I can put it through Applocale and get Korean characters!! But if I push the gamestart button then it gives me an error:
패스포트 스트링 오류 입니다. 다른 컴퓨테에 이미 로그인 되어 있지 않은지 확인해 주십시오.
I guess that means "There is a Passport string error. Please check if you are not already logged in on another computer." I am sure this is not the case, because the game runs fine when I click the gamestart button on the website.
Of course I tried this with Firefox open and logged in to nexon. (I tried with IE as well but it didn't work.)
I'm thinking that the KLunia and GLunia systems work differently. For KLunia you log into the website and then click gamestart. Then you run the client and when you push gamestart you just select the server and then character etc. I'm guessing in GLunia you have to login again?
I'm sure it is possible to get it working with KLunia, but I guess you need to add your username/password into the executable string as arguements somehow. I kinda hoped that if you had firefox running it would just pick it up for you but that doesn't seem to be the case.
If anyone can get KLunia working without the website I'd be really grateful. Not only is that more convenient, but then I can run it through Applocale. For some reason even if I set my computer's locale to Korean it doesn't work perfectly. The buttons on the client are still gibberish. (I had the same problem with TLunia.) So Applocale is the way to go, but I can't do so with the weblogin.
I also thought of running explorer in the background and making a shortcut to the actual gamestart button. While it may be possible, this probbably won't solve the applocale problem.
EDIT: Oops. If I put "LuniaClient.exe" instead of "Lunia.exe" it works!
EDIT2: Omg, if someone can hack Lunia.exe to make the gamestart button direct to "C:\Nexon\LuniaTest\LuniaClient.exe RUNGAME" that would be really awesome. Then we could patch it and everything. I tried putting the TLunia Lunia.exe in KTest's folder but that doesn't work. XD (Though the funny thing is TLunia's exe is more recent that KTest's O_o. Which might explain it.) Anyone have an old KLunia Lunia.exe? (If KLunia ever didn't have the weblogin system. I kinda get the feeling that they put the ingame login there for internet cafe use.)
