A universal computer-implemented method for submitting source code to an authorized game certification laboratory. Initial source code and subsequent source code patches may be transferred from the manufacturer's software development environment into the laboratory's software development environment in a controlled fashion using packaging installation technology normally used for deploying software applications. The packaging technology contains automation actions for automating the synchronization and/or management of the source code and related files between the two software development environments. The entirety of the source code or any source code patch sequence may be removed by executing the corresponding uninstall function. The package containing the original source code or the source code patch sequences and related files may be code signed such as to provide persistent proof of origin which may be verified at any time. The method may be implemented under any operating system such as Microsoft Windows, Linux, UNIX and Apple Mac OS without the laboratory having to learn a complex source code configuration management software.
