Transferring Saves to another computer

[sparkybruh]

Just a little background;
I had just gotten to the final boss of Persona 3 Portable before building a new PC. My old save- about 2-3 hours before the end of the game- is still on that laptop.
I do not want to go back to using that 4 core processor, integrated graphics computer.
How can I transfer my save to this PC to finish the game?
