title: How to interpret the opcode manually?
body: <pre><code>77f4bcbc 8945fc          mov     dword ptr [ebp-4],eax
  </code></pre>
  
  <p>And here's the rule:</p>
  
  <pre><code>88  /r   MOV r/m8,r8       2/2           Move byte register to r/m byte
  89  /r   MOV r/m16,r16     2/2           Move word register to r/m word
  89  /r   MOV r/m32,r32     2/2           Move dword register to r/m dword
  </code></pre>
