wow thanks for the fast reply, but I fear I haven't made clear, what I actually wanted.
What you just posted looks like a guide to add icons for items in rpgmaker xp.
I wanted to change the icon of the .exe-file that starts up your finished game.
For the rpgmaker vx the default icon is a little chess figure, while the default icon vor rpgmaker xp is an orange sun.
I want to change this icon for my project in a way, that it stays when the game is compressed and hosted.
