Open the folder the games exe and all the other stuff is in. Then open the folder named "www", from there you will see a folder named "save" you can copy that folder or if you want specific saves go in and copy those and move to the same location in the new version of the game. You will need a "save" folder either way so its best to just copy the whole save folder. After that you can run the game and it should have your saves in it. You can repeat this process for any RPG maker game.
