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.
No, you couldn’t because the PS3 has a very different architecture compared to most PCs. That’s what projects like RPCS3 have struggled since the beginning.
I remember reading back then an interview with a developer complaining about how difficult it was to make the port to ps3 for that reason.
Gabe Newell famously participated in an interview about the same subject when porting The Orange Box, and as a result handed the port off to EA (which ended up running like dogshit compared to all other platforms).
