Ok, being an expert on this I have the complete answer, and like all other times I've tried to answer questions like this I find 4 that have NOTHING to do with it.
Here's exactly what to do.
Unrar, zip, whatever the file so you just have the UDATA directory. Inside the UDATA directory cut one of the two folders and place it elsewhere (This should mean there's only one file in UDATA.)
Zip the UDATA directory, put it in Action Replay, should work.
Now for the other file - make a folder named UDATA, put it in there, then zip said folder. Put that in Action Replay also. This will register as two games, why? Because it is! The hack was split like this for some reason.
Simply copy over both of the saves that appeared in Action Replay, the hack should run. <
