Hello,
Im currently working on ez2on. I have a old game client and a server that can get the client into channel selection (
Recently I was lucky enough to obtain the latest game files before the server closed. As I rather want to develop agains the latest files instead of the outdated ones I require some help.
The problem is that I don't know what parameters to pass to lunch the game.
The old client could be started with simple parameters:
EZ2ON_EMU.exe 127.0.0.1 username password 1
But the current client always gives a message box, where the title reads "Run the game after logging in from the web" and the content is simply "-". Please find a picture of the message box in the attachment. (The title will look gibberish if you don't have Korean set as a language)
The aim is to bypass this message by patching the exe, or investigate the exe and find out how it needs to be launched (maybe it checks the parent process is a browser?, or it requires certain parameters) Any of those two ways that leads to launching the game would be a success.
So if you manage to get this exe to spit out a different message or launch the game, that would be great! If it's a different message please let me know how to reproduce it and I can translate the message to see whats going on.
The executable was protected by VMProtect 2.07 but I managed to unpack it with the help of a script (
There is also an anti cheat mechanic that will probably hinder further starting, but that can be dealt with when we actually figure out how to start this exe properly.
The binaries can be obtained from here:

Note I did not include the game artworks and song data, as this would blow up the download and is not necessary to overcome this message box. If you still want to obtain the full client please drop me a message and I will provide you the link
Any help is greatly appreciated, thank you for reading and hope you check this out, as my skills are limited in this area.
