Advice Wanted

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.

Hmm...I think I can't write my thoughts correctly or I don't understand something. I'll try this way, you told that graphics usually start at a round offset (0x20, 0x40, 0x60, etc..), so may it happened that one graphic start at round offset 0x000020, for example, and another at 0x000A7D in certain color depth?

And please could you help me, why relative search don't give result when I try to find dialogue text?
