Cathartes is obviously very busy with a new release but most of the points you mentioned will take you less than half an hour to change with LSA workbook. I bet Mark can help you as AFAIK he has an experience in CC data tweaking.
Back to playing this great version in Win 7. Along the "upgrade" path to Win 7 MS has changed the registry structure for the C:/Programs/Microsoft/Microsoft Games location to........which I found.
Hence, while you can create a folder for the installing in that Games folder, there seems no way to _install the game_ to that folder so it appears in the registry to enable editing the screen res. to higher then 1024 x 768 as per this older thread:
In August of 2004, Zappi, Homba, Bambam887, RedScorpion and MOOXE all pitched
in to create this Close Combat site. I would to thank all the people who have visited
and found this site to thier liking. I hope you had time to check out some
of the great Close Combat mods and our forums. I'd also like to thank
all the members of our volunteer staff that have helped over
the years, and all our users that contributed to this site!
