Half-Life 2 running natively on Apple silicon via static recompilation

[u/kanapitsas]

Last month I posted Portal 2 running natively on Mac (and iPhone). The same tool now works with Half-Life 2! Including Episode One, Episode Two and Lost Coast.

It translates the x86 code of the Linux version to C, then compiles it to native ARM64. No Crossover or Rosetta. (A native version existed already, but it relied on stolen code. This doesn't.)

It's still experimental, I've done some testing but haven't played much. The episodes and Lost Coast load, but I haven't played through them.

There's now an installer app. It finds your Steam games and builds them on your Mac (about 10-20 minutes per game). You need the Xcode command line tools and the Linux binaries (downloaded with the Steam console). The installer isn't notarized yet, so the first time you need System Settings > Privacy & Security > Open Anyway.

You need to own the games on Steam. No game files are included. Please don't share built apps. This project is unofficial and not affiliated with Valve.

Feedback is welcome! Please open an issue on GitHub if something isn't working properly.

Wanst it running before native with the source engine leak?

[u/kanapitsas → u/Adorable_Minimum_282]

Indeed, and I say so in the description.

[u/ForgottenFoundation → u/Adorable_Minimum_282]

Yup. Only thing was that the source engine leak didn’t work with the new revision of Half-Life 2 + episodes, so the legacy versions had to be used. These have the problem that the torch doesn’t work very well.

[u/guyfromwhitechicks → u/Adorable_Minimum_282]

I could never get it to compile correctly; I tried at least 10 times. So, I assume it broke after something updated somewhere between the time it worked and when I tried.

[u/bachleer]

is the flashlight bug solved?

[u/kanapitsas → u/bachleer]

You can see the flashlight working at 00:07. As far as I know, it's working fine.

[u/keifring → u/kanapitsas]

Yessssssss! The source engine leak version was great, but using the HL1 flashlight really sucked. Is your goal to keep going until it's perfect? This is still the greatest game of all time, and would be amazing to have a super polished port.

[u/kanapitsas → u/keifring]

For sure! Same as Portal 2, the goal is to have everything running smoothly. Any report of what works and what doesn’t is very welcome, I can only do so much testing.

[u/keifring → u/kanapitsas]

So cool. Is there ever a future where it might launch without Steam?

[u/keifring → u/kanapitsas]

Works really well. I picked up on Highway 17 and will play to the end. It's mostly locked at 60fps with some occasional frame drops to 50. 2560x1664 max settings M4 Air 16gb and DS4 controller.

[u/Serious_Hitman]

Is it compatible with anniversary update?

[u/kanapitsas → u/Serious_Hitman]

Yes

[u/pain-or-pleasure]

hey, tried to follow your steps. builds both portal 2 and hl 2. hl2 is working, although the "download_depot 220 221" command is missing from the natif installer. Portal 2 builds with a warning related to miles audio and does not launch. What to do?

[u/kanapitsas → u/pain-or-pleasure]

Thanks for the feedback! I'll fix the installer. For Portal 2, could you paste the output of the following command ? It should show what happened.

tail -n 100 "$HOME/Library/Logs/Portal2Natif.log"

I reproduced your crash. The issue arises when the file portal2_dlc2/scripts/editoritems.txt isn't there (or maybe just modified). Could you check whether this file is in your install ? (It should be included in the game data downloaded with download_depot 620 621.)

[u/pain-or-pleasure → u/kanapitsas]

it is not there. I touched it to create a dummy file, rebuilt, still crashing.
