so i've looked at this rootR.cpk from demo, and there should be 2109 files in there, at least from demo. i have made the proper folders for the files to extract, if someone is interested (you can view the proper toc with cpk_view.exe on offset 2064)...
the only way to extract these new cpks seems some generic extractor based on offsets or manual extraction, but with these lot files no fun. maybe someone who is able to update this quickbms script?
i've noticed quickbms can extract about 696 files and other cpk tools only 669, whereas all these seem to be broken and not correct, but i am not sure.
but i have repacked the map cpk and it worked fine on demo, so repacking with the free tool should work.
best and easiest would be some leak...and then there is still the jap eboot. in the end it will be a tb only
