box86 VS box64

The open-source and performant ones are https://fex-emu.com/ and https://box86.org/, but they are not written in Rust. Their documentation is probably the best bet if you want to build something along these lines.

Maybe Box86/64? https://box86.org/

On the official repo if you scroll down there is steam compatibility and it says that in the root of the repo there is the steam install script. https://github.com/ptitSeb/box86

That means it'll need a 32-bit emulator to run on, but as it says on box86.org, box86 only runs on 32-bit ARM chips. Hence it runs on a Pi2 but not a Pi3 or higher.

Recently, I got a server from Oracle Cloud, having 4 cores and 24GB of RAM. Then, using a software called Box86 and its 64 bit version called Box64, I succeeded in running Factorio! Unfortunately, 1.1.80 ran at 3 UPS! I went through each major version, testing each individual one down to 0.12. Here are my results!

Unfortunately box86 requires a little-endian processor, and the G4 is a big-endian processor so it won’t work

In the video, they mentioned they can't run steam on RISC-V because box64 doesn't support 32bit apps. In the README of box64, it is mentioned:

I see it can do more now, already tried some stuff. But see it is now more mature than months ago. Will try factorio again https://github.com/ptitSeb/box64/issues/665

Also, in the discussions of box64 is this thread: https://github.com/ptitSeb/box64/discussions/524 My guess is that you have to install both box64 and box86, the latest mesa drivers with vulkan support. And then try to launch the game with proton. There is also this issue that shows factorio running on a Rock 5B: https://github.com/ptitSeb/box86-compatibility-list/issues/284

In Box64, which is an emulator+JIT recompiler, and thus likely pretty slow?

macOS runs x64 executables just fine through Rosetta so I don't see why Wine couldn't make use of that hardware acceleration.

It's also possible to only simulate the entrypoints through Rosetta and then execute native aarch64 code from there. On Linux https://github.com/ptitSeb/box64 does exactly that, for example. However, with the performance Apple has been able to squeeze out of Rosetta, I'm not sure of that workaround is even necessary.

You could try https://github.com/ptitSeb/box86 and https://github.com/ptitSeb/box64/ , I believe they allow you to emulate x86_64 on aarch64, though I have no experience with them, so cannot say for sure.

git clone https://github.com/ptitSeb/box64.git

If you have time and patience take a look at box86 and box64. These are basically like translation layers that allow x86/x86_64 applications to run on ARM. I personally haven't use them yet, so I can't provide a guide or vouch for game compatibilities. But by the look of the progress made by them so far it looks promising.

You can follow progress of this on https://github.com/ptitSeb/box64/issues/635
