<h1>Hexadecimal Wizard by DNA64</h1>


<p>This simple web-based Hex tool will save you a lot of time when using Cheat Engine.<br> It will increment the user provided byte values by the difference between the current item quantity and desired. <br>If you don't know what this tool is for, it's not for you ;)<br>
