First off, start the game once. Start one of the emulated games for good measure.

Then, copy the following line into a Windows Explorer box:

%USERPROFILE%\Saved Games\Limited Run Games\Jurassic Park Classic Games Collection

And on this game, it's that easy. You're there.

Here are save files made right before getting every achievement in the game.[drive.google.com]

All you need to do is pick the folder with your achievement of choice, open it, copy the numbered folder ("0", "1", "2", "3", "4", "5" or "6", depending on the game) into the folder in the previous section (%USERPROFILE%\Saved Games\Limited Run Games\Jurassic Park Classic Games Collection), and then start that game and load the save file.

You can do this while the game is running, it works fine, unlike some other games. If you do it with the game off, turn off Steam cloud saves, as it may revert to your previous file (right-click on the game in your steam library, go to Properties).

Once in the game, the achievements should unlock. In a few of the games you have to make the last motion before beating the game - collecting the orb, typically, but it should unlock after it counts the final score.

Feel free to use these as you wish, but I recommend trying to play the games and have fun to get the achievements. But if something glitched on you or you don't want to play some of the games twice, well these are here for you! I had them lying around my hard drive anyway.

Hopefully this helps you in either backing up your save files or getting that one last nagging achievement! The files should all unlock an achievement, I tested them on another Steam account in my family and got all achievements in 10 minutes.

Let me know if you need further explanation or have any thoughts in the comments.
