pos.ini

Open pos.ini with something like notepad and examine each line.

As you can see some items have 1 comma and some have 3 comma's after the "=" character.
Here you place each button in players to the position you want them to be.
The value of Top & Left and examined from PlayersPanel position.
So when your left eject button should be in your playerspanel image at Left = 12 and Top = 45 then you enter Eject1=12,45
The right player has a "2" in the text so that could be for example: Eject2=12,345
