This may be a bit misleading. You do initially need the internet, but after that, you can be offline. This will help those that don't have internet at home or those that will be left without internet for a while. Note: This works for Windows XP, I do not know about Vista.
1) Download and install a personal web server. I highly suggest 'Abyss Web Server X1'. But, if your computer can't handle background processes and PSU, then I suggest 'Apache'.
2) In the "C:\Program Files\Abyss Web Server\htdocs" directory (or where ever else you installed it to) the following folders need to be created in this order:
"GameGuard\SEGA\SEGAPSU", so that your directory looks like "C:\Program Files\Abyss Web Server\htdocs\GameGuard\SEGA\SEGAPSU".
3) Now for the gameguard server files. Click on: http://update.nprotect.net/GameGuard/SEGA/SEGAPSU/....
It will take you to a Index Of page. Download them from the list there. If you don't see the list, or are blocked from it for some reason, copy the above URL, and paste the file names at the end.
gamemon.npz
ggscan.npz
npgg9x.npz
npggNT.npz
npgmup.npz
nppt9x.npz
npptNT2.npz
npsc.npz
NPSCAN.npz
SEGAPSU.npz
splash.npz
update.cfg
4) Put the downloaded files into the htdocs directory.
5) Open C:\WINDOWS\system32\drivers\etc\hosts (open in notepad)
6) Add the lines:
127.0.0.1:80 update.nprotect.net
127.0.0.1:80 124.78.4.91:DNS
127.0.0.1 124.78.4.91:DNS
127.0.0.1 update.nprotect.net
below '127.0.0.1 localhost'.
Notes: If there are grins in the lines, replace the grins with a colon then a capital 'D'. Also, if your OCD kicks in, you can press tab to align the addresses, but it isn't necessary.
7) This is important! Save the hosts file, then right click > Properties. Click on the read-only box, then OK. GameGuard is aware of this workaround and will nullify the entries if this is skipped.
8) If you already have gameguard-updated files, go into the C:\SEGA\(PSU Folder). Delete the GameGuard folder.
9) Start up PSU.
If you see 'authenticating' even when you aren't connected, then it worked. If not, let me know if something didn't work that was said in this guide. But, double check first, please.
This completes the process of using offline mode, offline. If you can't download at home, but still have access to downloading, then I suggest a flash drive. Or something else to that effect.
