No problem. You can use the same process to transfer your PS3 PSone saves to your PSP too. If you have a Memory Card USB Adapter you can transfer your original game saves this way too. The original saves from an original PS1 Memory Card are compatible with any of the PSOne Classics (at least all the games I have are). Have fun gaming!
Feel free to add me as a friend. Just put "playstation forums" in the friend request.
