Hey all, I recently stumbled upon my Links 2003 CD version game stuffed away in a box. I say what the hell, might as well install it again and play some golf. Well everything installed correctly with no errors. Installed the v1.05 patch. Untill it was time to play. I too got the insert CD error. But the CD was in the drive. After many days of searching I havn't found the reason why this was happening but I have found a fix that will remove the copyright protection. Thus, being able to play without the CD.
The program is called SafeDisc2 Cleaner. I don't want to post the download link here because it might be illegal for the forum rules.
Links 2003 uses safedisc 2.60.052 as its copyright protection and this program will get rid of it.
1. Download and install SafeDisc2 Cleaner
2. Point the program to the RuKsHuK.exe file locted in links 2003 directory
3. This program will create a file called SD2cleaned.exe
4. Rename your your original RuKsHuK.exe to RuKsHuK.exe.bak
5. Rename SD2cleaned.exe to RuKsHuK.exe
6. Enjoy!
