Identify in memory format of script engine data -- 2

I need to access data stored in a custom script engine used in point and click adventure games. I seek access to the current status of in script variables and items. I need reliable access, valid across multiple play sessions, to in memory copies of the variables. I plan on accessing the data using the windows API function ReadProcessMemmory in a program of mine. I also need to find the file format used for the custom file format used by the engine. I need access to the script used in the game. Since it is a single player game, there is no networking involved, no server and no peer to peer communication, so no such skills are needed here.
