Linux Userspace x86 Emulator with a twist
Box86 will let you run x86 Linux programs (games) on non-x86 Linux, like ARM (needs to be 32bit little-endian).
Also, Box86 uses the native version for some “system” libraries, like libc, libm, or SDL and OpenGL, leading to more performance and easier integration with the host system.
Most x86 Games need OpenGL, so on ARM platforms, a solution like gl4es is probably needed.
Note that the current version of Box86 doesn’t feature any form of JIT/Dynarec: expect everything to be slow.
The current version is still experimental, so some stuff still wont run. But many do work, like for example, WorldOfGoo (at least on the Pandora), Airline Tycoon Deluxe or new FTL. Many of the GameMaker linux games also run fine.
If you are serious about developping Box86, you should install ccache and activate it’s support in the cmake project (use ccmake for example)
To have TRACE enabled (i.e. dumping to stdout all individual x86 instructions executed, with dump of registers), you’ll also need Zydis library accessible on your system.
Some x86 internal opcodes use parts of “Realmode X86 Emulator Library”, see x86primop.c for copyright details
Here are 3 videos, one of “Airline Tycoon Deluxe” running on a gigahertz OpenPandora, and the other 2 of “Bit.Trip.Runner” and “Neverwinter Night” running on an ODroid XU4.
How to compile can be found here
There are a few environment variables to control Box86 behaviour.
See here for all variables and what they do.

A note about Unity game emulation
Running Unity games is not possible for now. Mono itself uses signals that are not well emulated enough. So the solution is to use a native version of the libmono used by unity. It can be found here: https://github.com/Unity-Technologies/mono and it needs to be built from source. When built copy
libmonounity.so and put it somewhere it can be dlopen’d (so in
usr/lib or friend or somewhere in your
Note that libmonounity is not completely wrapped yet, and the mechanism to call x86 library from libmonounity is not done yet
