Ok, first let me point out that I've never made a rom hack. I don't have a clue what I'm doing. I googled for some programs, I found them, I'm trying to use them. I managed to edit levels just fine.
Now. I'm trying to change the title screen on Super Mario Bros for NES. Should be simple enough. I downloaded this SMB Title Screen Editor
. I've edited the title screen, but when I go to save, it gives me THIS
popup, and doesn't actually save. It has an English readme, and I did exactly what it says to save, and it still doesn't work.
Any solutions, or other programs I could try? Keeping in mind, I know nothing about Hex, or coding, or anything more complicated than click a sprite, add a sprite. So, an easy to use program with a GUI would be best if you suggest something..
