well yes....and no
since the nv mod has changed all the reserved GVARs to have the same name, the question i have is...does the game save them separately or just overlay them (cos that would be bad...yes?)
MasterHan:
actually i meant country version. anyway we may not need that yet...
1: Clean install FO2 (uninstall, delete fallout dir, install)
2: Extract the megamod & the megamod update to two separate folders.
3: Move all the folders from the megamod update into the data folder of the megamod.
4: Move the fallout2.exe from the update to the megamod folder
5: go into the sound\music folder of the megamod and delete all the music files (*.acm) except 25sewer.acm (all the others are already in FO2)
6: In the megamod proto folder set all the files to read-only.
7: The megamod folder should contain fallout2.exe and a data folder.
8: In the fallout2 folder, delete or rename the patch000.dat file (if it exists).
9: Final part, To install just copy the fallout2.exe and the data folder to where you installed the game. (if you don't get asked about overwriting the exe and the data folder then you've done something wrong)
NB: if you keep the megamod folder as is, it makes for an easy re-install.
try it, you'll like it
