Linux and console games

So since the ps4 for an example is running OrbisOS which is linux based, how is that mw2 can run on it while a linux desktop based OS cannot run it becuase of the anticheat?

PS' OS is based on FreeBSD. And just because they have a similar kernel, doesn't mean that the rest of the stuff on top if it is any similar.

because the PS4 is still a very locked down platform, to the point this common knowledge that playstation has been BSD based ever since they had an OS at all is not all that common. they chose BSD because it's a solid base and the licensing allows them to create that locked down platform with it.

 

essentially, it's not because the OS itself is linux or BSD based, that it has any implications for anticheat. the problem about anticheat on linux is more a 'potential marketshare' and 'the willingness of that potential market to install very closed source software on their box of freedom' kind of problem.

 

there's nothing about windows that makes anticheat "possible" on it. it's that linux can be a very powerful platform for working around the things anticheat does, and it's sort of implied that if anticheat were to limit that freedom, it would quickly be as unpopular as windows in those circles.

so.. we're talking about a small portion of 4% of the pc users market that might buy a game if it had anticheat on linux.

So then technically speaking running freebsd on a desktop which is running mw2 should be possible or is it a PS exclusive thing only?

PS4 is not running a desktop operating system. there is no reason to assume any software running on PS4 will run on a BSD desktop.

It is based on FreeBSD, it's not BSD per se, and I guarantee you that the userland has nothing in common with a regular FreeBSD desktop. So no, you couldn't run those games easily in other system.

Just like running steamOS on desltop has something similar ever been done for OrbisOs?

SteamOS is pretty much a regular linux distro running on top of a regular x86 machine, with UEFI and whatnot. The PS' system is entirely different. You can get the gist of how different it is by watching this great video:

Going the other way around would be way too much trouble and hard given that we don't have the source for the system.

Thanks! I will be sure to watch the video.

if this was as trivial as you think it is, we would have a 100% support PS4 emulator already with great performance.

Haha but in theory it should be possible though right?

just like in theory it's possible to drive your bicycle on a railroad.

Practically asking/speaking is it possible?

about as possible as making a space rocket in your back yard.

 

you're talking a purpose-made operating system running on a less than conventional computer (running GDDR5 as system memory) that probably only has the specific drivers for a given piece of hardware. the software for that platform then only needs to take into account the specifics of that given platform. there's no window manager, there's only standardized peripherals, etc.

 

under the hood xbox one is running the exact same kernel as windows 10, but everything on top of that is so different that it's rare to see a pc port from a console game to originate from the xbox version. if this were feasible at all to do for a single person, the game companies would be doing it too.

Ah that makes more sense now but how was the ps3 been able to be emulated on PCs? Sorry if I am asking all these shitty questions, I just want to know more about emulation in general

the same way every other console has been emulated, by making a software layer that acts exactly like the hardware+OS, but with calls back to regular things like a window manager. it's inefficient as heck, but it works.

So it’s essentially a virtual machine with an abstraction layer?
