Since the PS3 ran on modified OpenBSD, would it be possible to run physical disc games trough a disc drive on a Linux laptop by downloading the needed libraries? In what way would I need to modify the games/system?
Would the architecture play a big role? My thinkpad barely runs RPCS3 but can handle AAA steam titles.
It's a different and completely unique architecture than what runs on most PCs out there, even what runs on most older PowerPC platforms. It wouldn't be possible to run PS3 games on PC hardware without hardware emulation. PS4 and PS5 might be possible since they use x86_64 CPUs and AMD APUs and their OS is BSD based but it would still be challenging to coax them into running on PC hardware outside of the PlayStation Operating System.
