I spent quite some time studying the Pascal and Assembler source code, but could not resolve all symbols, and there are also several ambiguities, which led me to the conclusion that I would also have to build an interpreter for all the build related files and try to reconstruct a complete build with the correct options in order to be able to make any statement about the completeness and integrity of the code. That would take a lot of time at the expense of my other interests. That's why I've put the project on hold for the time being.
