How do you get a Monster Hunter saved file from the internet to your memory card

First, you create a new, empty save. Then, you either connect your psp to your PC using your usb port, or if you have a cardreader you simply put the memory stick in. You then navigate to your saves folder, and find your new emtpy save. Then you rename the downloaded save file to the same name as your new save, replace it, and it should work.
