Getting downloaded save files to work?

My Phoenix Wright save was wiped and I downloaded another save file to go back to where I was but it won't work. I re-name it to the same as the file but without the .nds and it just doesn't register. Any help?

What flash cart are you using and what firmware is it running?
miros

You may need to convert it. http://shunyweb.info/convert.php

The card is R4i Gold or even R4SDHC. I am downloading the file and its called 'phoenix_wright_2_eu.dst'

What is the end of the save files that your flashcart usually use ?
Try Anandjones method.

Nothing, it is just the file name minus the .nds

Copy it to a PC, I think you can see it on a PC.
