Advice Wanted

I meant if I already have a some tiles, which looking normal (for example, when I open ROM file with Tile Editor character sprites are looking normal), can I be sure that I don't need to push these buttons for the purpose of finding other tiles that look disrupted.

Data or code would never look like disrupted graphics so if you see a disrupted region it's graphics so you just have to change the offsets by a few bytes to see them clearly.
