Hi, I did get it running off the hard drive once
First Create a directory on your harddrive called
SC3cd (or something)
Second copy the entire contents of the cd to the directory making sure to keep the structure the same
Third edit the SC3 data files to point to that directory instead of Cd-rom drive, *checks to see which file it is*
Legend.ini file, there's three directories to change.
PICDATA=G:\
VOCDATA=G:\
QDATA=G:\Q\
In this case G is the cdrom so you'd change that to
PICDATA=C:\SC3cd
VOCDATA=C:\SC3cd
QDATA=C:\SC3cd\Q\
If you were using C drive and had created a directory called SC3cd.
That's all there is to it (I think) let me know how it goes.
