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.
The PS3 runs on an ancient fork of the FreeBSD kernel. We don’t even know which version. No compatibility even on syscall level.
Now, I remember that some random person added Nintendo Switch syscalls to Linux aarch64 then took GPU emulation from Yuzu. They stopped when it ran some Tetris. Now, that was relatively easy given the Switch doesn’t have too much of special hardware. Also, the CPU there only has the base instruction set + md5 extension, basically every aarch64 chip has that.
Now, the PS3 is full of random DSPs (basically coprocessors that are shit at everything except some specific tasks). And even if you get a PowerPC machine powerful enough (like some decommissioned server), it still probably won’t match all of the instructions. Catching SIGILL to emulate them… meh, you are basically writing an emulator. Which I bet would be slower than just emulating the whole thing at once.
