FullDisasm 3.0.1.172

A small plugin for Immunity Debugger which allow you to replace the old disassemble routine used in OllyDbg by a more recent one (beaengine). With this plugin, you can now debug FPU, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2 and VMX without problems.

Example :

00401000 PSLLQ MM0,QWORD PTR DS:[402020]
00401007 MOVQ MM0,QWORD PTR DS:[402020]
0040100E MOV EAX,1235
