Two ways
Online (Easy but got money involved)
*subscribe to PSN Plus , which gives you permission to upload/download any of your save file , so once you finish playing the game at SG , (it should sync the safe file automatically to cloud ) , if not just sync manually , then go to your MY PS4 , and sync back (usually after turning on PS , it will sync automatically ) or you can do manually.It gives you 10GB cloud storage , which is big enough for save files...and if you set things up correctly , you wont even notice this whole save file data thing as PS4 sync upload and download seamlessly.
USB Storage.(Manual , abit hard )
*Once finish playing the game , save it and plug in your USB , once detected , you can transfer your save file.Go to your MY PS , plug in the same USB , upload/copy it , then load the game with the save file , not really hard , but USB gets missing easily , so yeah...
Either way , it's possible to copy/transfer your save file , but make sure both system logged in same acc , cause those safe file are tied with the acc , means that you can't use the save file with diff acc even its the same game....
Ps4 console is region free , but the game aren't , idk much about that , but if you use the same disk to play on both console , the save file will be good to use i guess
I tried before , but my game was digitally downloaded , it worked for me , it should work the same for disk i guess...anyways good luck and inform me the result , i wanna know too
Great! Thank you so much!! that's what i have been waiting for.
You mentioned about same acc. Meaning i have to set my PS4 SG as the primary account, after that i could use the same account on my PS4 MY?
I will definitely try this weekend and update you.
