How do I make a custom ending?

[D12]

Since i'm making a boss map in my wad, after I defeat the boss I can see my custom textscreen but when I click further it shows the doom 2 cast. What I want is a custom picture pretty much not the Doom 2 cast screen. Can it be edited via mapinfo?

 

Edit: I managed to find it out! but I can still use some advice for scrolling haha.

Did you figure this out? You can use MAPINFO to make it so that, instead of going to the next map, it goes to a variety of different possible endings. Some info here:
