Linux

First of all, don't expose yourself to danger. Get your pirated games from reputable sources.

Most games only need a Steam emulator like Goldberg's to run without license, and you can get clean steam files from cs.rin.ru. You don't need VMs for this, it's literally the original game.

If you need an actual crack, you can also look up on cs.rin.ru and try to gauge the reputation of the uploader. You can also check fitgirl or dodirepacks, they are both highly reliable. These are unlikely to have malware, but it's not impossible.

If you want to use a vm because you still don't trust the pirated game in question (reasonable), then there is no shortcut. Use the arch wiki to learn how to setup a VM with GPU passthrough, even if you don't use arch it's always a good place to get started.

tldr: use firejail. I already answered in your other thread: https://feddit.org/comment/13927222

You know you can cross-post so it shows up as cross-posted in other communities? You just need to hit that "copy" button once you posted the first one.

I'd have answered here instead of !piracy if I had seen that it's a crosspost.

You keep talking about "safely" running these programs. What is the threat that you are trying to protect yourself against? Are you concerned that your unofficial copy of the program may contain malware, are you worried that the copyright owners may try to find you (via IP address perhaps?) and prosecute, or what.

you can with GPU passthrough. not a simple process though, and not all hardware supports it.

plus you need a dedicated gpu for the VM.

I'm running everything that is proprietary (Steam for example) on a second user that is a not an admin account. Heroic and the like are installed via Flatpak that is sandboxed. Sometimes games contain malware, even on Steam. If something goes badly wrong, I purge that second user.

I just use a different user with no privileges to run any pirated or suspicious software.

So I'm not condoning or condeming.

I would say you can dual boot linux - that is have TWO entirely separate Linux installs on your PC. Have one be your main Linux desktop, and have a separate partition which you boot into to use for riskier stuff. Just ensure it has no access at all to your other drive and be careful mouting peripherals like USB drives. That way you can get full native experience with your PC, without having to sacrifice performance for a VM set up. I would also set up a VPN to run at all times within that 2nd Linux install, with kill switch for the network if it disconnects.

OP, FYI: GPU passthrough isn't riskless (OpSec-wise), unfortunately. This Hacker News thread contains pointers if you'd wish to read up on that.

im not a linux expert but isnt the whole thing with linux that there isnt really malware for it because no one bothers to make any?

but with regards to games like other posters said check cs.rin.ru for the games and either use the goldberg method or just get the games pre-installed/cracked and run them through Lutris/Heroic

alternatively you can also download linux versions, theres a couple of people who crack linux games, one of them is john_cena and another whose name i forget is on torrrminator. ive downloaded a couple games from torrminator and had no issues with them

but of course ymmv and this may not be entirely up your alley with regards to the privacy etc concerns

QubesOS? :D
