[Playing RCT1 on OpenRCT2]

Thanks for responding - should it be the csg1.dat and csg1i.dat from the original RTC1 CDrom, or from Loopy Landscapes that I copy over?

 

[Playing RCT1 on OpenRCT2]

I'm new to OpenRTC2 and have tried to link both my RTC1 and 2 installations.  I have both installed from the CD Roms with all of the add-on packs.  I've been able to play RCT2 without any problems since I first installed, but RTC1 and Loopy Landscapes have been less successful.  I first saw a message saying that I needed to copy a csg1i.dat file from the CD to the local folder, which I have done.  Now when I try to select the path, I see the below error.  I've found discussions of using installations from downloaded versions, but is there any advice on how to link the CD versions?
