weird that so many vista users are having problems running the game and i am using vista 64bit (runs flawlessly)
not sure this is the correct way but here is what i did
0. rename chaos to *.rar.part1 ..part2 part3 and unrar it
1. mount iso with daemon tool, run chsetup.exe with applocale (i hate gibberish fonts)
2. copy paste nodvd crack to game dir
3. extract jp_1-10_beta.rar, copy installation.bat and nss.rar to game dir (ran it there but not sure why there is no nss folder created)
4. so i click installation.bat again(inside jp_1-10_beta folder)
5. copy paste nss folder to game dir
6. run chaoshead.exe with applocale set to '日本è¯'
here is what it looks like after patching (ignore the backup file)
