Come in handy when i browse through ram editors in games in search for values. It still has 1 minor flaw - A,B,C,D,E,F symbols are almost the same color as buttons. When i put screen brightness to minimum they are barely readable. Make them white please, so they can be clearly visible. ### 5/5 — Thank you!
