Buy digital games on each account: you can play at the same time
I would recommend not to bother with trying to game share using the method I described below, as it's very error-prone, and in the worst ...
There will be no problem running it but you cannot get any preorder content, DLC, or anything else associated with a code since it will be tied to the store in region 1. You can get around this if you'd like by creating an account in region 1 and making your PS4 the main PS4 of that account which will share all content from that account with other accounts ...
It is possible to perfectly emulate the PS3 on your PC, with superior 4k 60fps graphics. MGS4 recently was made compatible for the PS3 emulator, and you can play your own legally paid for copy on your PC.
