Hi,
it is very easy but may take some hours...
Download this instruction set...
now what the hex code you are having... break it into number of hexadecimal numbers of two digits like ... C7 , E5 etc...
Now corresponding to each hexadecimal number - find a corresponding instruction ...
See page number 7 of this pdf file. Also see the column on same pages naming 'number of bytes'.
PS: I hope there may be some softwares available online ...
But try above method...
