How to Change the Loading Screen Background

To change the background tile of the loading screen when starting or changing a map, insert the following code in your CON files:

onevent EVENT_GETLOADTILE
 setvar RETURN <tilenum>
endevent

Replace <tilenum> with any tile number you like to display it as your custom background loading screen. Adding 16384 to your number will stop the "LOADING" text from showing.
