I’ll try the FEditor way.
The black strip on the side is present on most of the backgrounds already in the game.
Fateborn > I gave all the details. There’s nothing more to do if you wanna insert things with GBAGE ^^
Also, I don’t know the palette of the original background. the greenish palette of the Dragon gate.
The problem is that I don’t really understand how the FEditor CG maker works. I don’t know what to do with the files it gives.
First file is a .png of what your image will look like in-game(save as .png)
second is the image data(save as a .dmp)
next should be the TSA data(save as .dmp)
and finally you should get the palette data(save as .dmp)
(I might be wrong on the order for the last two, it’ll tell you which is which)
Insert all of that data in your rom word aligned(as in the offset ends in 0,4,8, or C)
then you want to use blazer’s cg editor module
find the bg that you plan to edit(don’t use any CGs from Lyn Mode, they act strangely), and edit the three offsets(image data, tsa data, palette data).
after that you should be all good!
