    Hello all, welcome to my first unpackme. It won't make your code smaller though, it's more of a protector. The attached file is a simple window. The goal is to restore the .exe to it's original transparent state, and if it were a real app it could then be reversed. Compiler: mingw Name: simple Difficulty: 1 or 1.5 / 10, no anti reversing/debug Feedback is welcome, do enjoy and thank you for reversing! SimpleUnpackMe.rar
