Custom1=1 ???
 

I guess this question implies that I'm still pretty new to WHDLoad. But I'm eager to learn. ;)

When loading games via WHDLoad the loading screen sometimes tells me stuff like "SET CUSTOM1=1 for infinite lives". Well, where can I do that?

Thank you in advance!

Click on the icon of the game, hold down the right mouse button, select 'Icons -> Information...' from the menu at the top.

Vielen herzlichen Dank!

You're welcome :) (English only here please ;))
