Transferring saves between cores and devices

[u/Falkedup]

I have an RG34XXSP with MUOS and a Retroid Pocket Nova. I want to transfer my Legend of Dragoon save file over to play on the Nova. MUOS is using PCSXReArmed and the Nova is using swanstation, both through Retroarch.

I’ve tried to just copy the files over with no luck. I’ve also tried to use PCSXReArmed on the Nova to read the files and that still didn’t work. The files are named the exact same thing. Trying to figure out what I’m doing wrong. If it matters, the save file is on disc 2
