Reinstall on different OS - how do I use my save files?

I've been playing FFT on ePSXe for a while and when windows died I threw on a fresh copy of Ubuntu. I installed ePSXe through an automated script and it configured my plugins so idk what's different, but my old save files are arranged as:

/Save/Slot1/Save01
/Save/Slot1/Save02
...
/Save/Slot2/Save01
...

-- how do I use these save files? What plugin do I need?
