[Help] Creating Custom Mu.exe

Hi!

As the title says, I wanted to create a custom Mu.exe for 1.04D client. I wanted main.exe to load it automatically and Mu.exe will check for updates and launch the game if all is set. What I have done so far is:

1. Custom Mu.exe launcher - Done
2. Double clicking main.exe will run Mu.exe - Done
3. Clicking Start Game on Mu.exe will execute Main.exe - Done
4. .. this is where I'm puzzled. When main.exe runs it will launch Mu.exe again which is not right. I might be missing something here which is beyond my knowledge.

Is there anyone who can help me figure out what I missed? Or did I do something wrong here?

Someone might ask me why not use the default Mu.exe? Well, maybe because I wanted to customize how Mu.exe works.

Thank a lot guys.
