If you simply don't know how to edit the credits, then open the Overworld Editor
, go to File > Credits > Load Credits... From there you can edit SMW's credits similar to how you'd edit the Overworld.
I know how to load the credits, I just don't know how to edit them after I load them.
What I am doing is:
Overworld Editor > File > Credits > Load Credits...
Then from there, I click the iceberg to open the 8x8 Overworld Tile Selector/Tools but then when I try to edit the credits, it doesn't do so. The only thing I've managed to do is fill the whole screen with the letter I've selected, I just want to fill one tile.
