x86 instructions interpreter

Dear Coders, We need an application that allows us to obfuscate some code in our application by converting the original x86 binary opcodes into virtual opcodes which will be emulated in runtime. Basically, we need an instruction obfuscator similar to VMProtect ([url removed, login to view]). We don't require a user interface, we just insert a specific assembly code pattern (start - end) that will be recognised by the obfuscator and will convert the x86 code into a virtual pseudocode. Requeriments ------------ 1) The solution will be coded in C or C++ using Visual Studio 2003/2005 2) The original assembly code will be converted into a interpreted one. This interpreted code will be placed into a new section in the PE header along with the code that will be able to interpret that virtual code in runtime. 3) The handler of the virtual code will be different eveytime (mutable) so, we avoid that a cracker genereally recognised how the instruction are executed 4) The virtual opcodes are different everytime that we protect, so we avoid a general attack. 5) The more similar to VMProtect, the better and good bonuses for this ;) If you have any questions, let me know please. Thank you!
