Jazznazz, are you able to send me an extracted copy of the demo? If possible, I would have no need for extracting the demo. I read the post you have up before, I didn't understand one bit.
Copywrite issues.
Lots of demo trainers that work just fine in the download section here and or on the old site.
Now as far as the FULL game goes.....
Besides the "how to" text I THINK there is an extractor in the download section also.
I forget which patch it was but the game devs made it so certain things in memory would have NEW LOCTIONS each time the map changed or the game was restarted in an attempt to stop "trainers" from operating.
On new maps/games even with an extracted game you need to use the memory tools to find and then enter the new values.
The thing is this only seems to happen with XP....and almost nobody uses 98 or win2k so they did not waste any time to address those OS's.
Nobody who had ME kept it as it needed a patch for EVERY program.
#1: You can learn how to use the TOOLS which may take time away from the game for awhile......or
#2: Used diskcommandor/partitionmagic or some sort of utility to make a partion on your C drive and install Win2K on it!
