title: Calculate the JMP opcodes
body: <p>I'm trying to calculate the correct op codes for a jump, I've looked at this in other threads and I still don't understand:</p>
  
  <p>I thought the formula was <code>desination - (from+5)</code> but its just not working, it's way off, here's the addresses that I want to jump to/from:</p>
  
  <pre><code>FROM: 6259326B
  TO:   02980000
  
  CORRECT OPCODE: E9 90CD3EA0
  FORMULA OPCODE: E9 5FC13266
  </code></pre>
  
  <p>So I'm having problems with this, any help appreciated.</p>
