For this mission you are going to need two programs.They are: OLLYDBG: and P32Dasm and you can get them from these two links www.ollydbg.de/download.htm and progress-tools.110mb.com/p32dasm.zip - Now the more informed of you who know what P32Asm is used for will already know how the program was made.
