The real reason why i posted this question in this forum is...
I had a copy of "Trackmania Sunrise" from my local videostore.
As the game was great fun for me i decided to buy a copy
on ebay. Of course i have to wait several days for it to arrive.
So i did the following trick. I started Trackmania Sunrise before
i gave back the copy to the videostore. Then i shutted down
the computer using the suspend to disk mode of windows whenever
i had to leave for work etc.
When i came back i just "woke up" my computer and the game was
still running (and working .. without the cd).
As i remembered there was a possibility on the Amiga to freeze the
memory state and load that image to the ram everytime you wanted
to. So i came up with the idea of doing the same on the pc.
But as i thought there seems no possibility to do this as a computer
running windows is far more complex than an old amiga
Nevertheless i thought it would be a good idea to ensure that
this is right, so i came up with that question here.
Sorry if that thread wasted your time

....and thanks in advance for your answers!
btw. the game arrived me today ... so now im gone playing
