^ AAA streamed script is apparently a test script, meaningful for debug builds, which contains no intermediate code and is supposed to store the 8 bytes coming with the sixth header chunk of the script multifile relevant to match the Cd image where all streamed scripts have been compiled and archived into (notoriously in script.img). It is advisable to compare data on the basis of the script size rather than of a fixed length (the way it might have been designed to);
^ The header chunk is fetched as normal code and may be mandatory only in script multifile if streamed scripts are present or, even more strict, if AAA test script is compiled;
^ A hint or what matters to get the test script filename (AAA might be purely conventional). If the file offset does not match the one of the very last streamed script, a binary search of the entire array with an element less could be performed.
