Watch out for the PSP and Sega CD saves, they were moved from System/BIOS dir to Savefile Dir (if you have them in different places than ROM folder).
Sega CD (Genesis Plus GX):
Just move these files:
– cart.brm – scd_E.brm – scd_J.brm – scd_U.brm
to your Savefile Dir
PSP (PPSSPP and PSP1 cores):
Move the PSP folder, inside System/BIOS / PPSSPP folder to your Savefile Dir
System/BIOS
|---> PPSSPP
|----> PSP ---> this folder!!!
