D2 Loader?

[Shift]

Open your diablo 2 directory and create a shortcut of d2loader-1.11b. Right click the icon on the desktop and choose properties. On the target line, you should see this

"C:\Program Files\Diablo II\D2Loader-1.11b.exe"

to add what you want to it, leave a space aftre the quote and put -w then another space and then -skiptobnet. It should look like this

"C:\Program Files\Diablo II\D2Loader-1.11b.exe" -w -skiptobnet

Hope that helps.
