- Export your save from your PS3 (under games in the XMB, go to saves, export, export to USB).
- Put them in the proper location on RPCS3 (manage → save data, open a random one, go up one level, put the folder here)
- Download and install apollo save tool on RPCS3 (go on github to get the pkg, drag n drop it into RPCS3 window)
- Open Apollo save tool, open HDD saves, open your save and use “export decrypted save” or smth like that on all files that are available there
- Open the location where those files are (apollo will tell you), overwrite the save files from step 2
- Launch the game :)
