Sadly, I don't really understand how the code works, I tried to find where the values are stored and to check for myself (to save you work), but wasn't successful. Of course not everything has to be included (like the over 200 Gold questions), but some changes seems reasonably, and in the forum nothing else was found back then.
I gathered the changes and other inconcistencies of these files in a sheet. It's not a typically bug report, but more a question/discussion if my fix for the BIOG files are already included in DFUnity and if not if these changes should make it into the basic game or should be added as a modification.
