Linux Userspace x86 Emulator with a twist

Box86 will let run x86 Linux program (games) on non-x86 Linux, like ARM (needs to be 32bits little-endian).

Also, Box86 use native version for some "system" libraries, like libc, libm, or SDL and OpenGL, leading to more performance and easier integration with host system.

Most x86 Games needs OpenGL, so on ARM platform, a solution like gl4es is probably needed.

Note that current version of Box86 doesn't feature any form of JIT/Dynarec: expect everything to be slow.

Current version is still experimental, so some stuff still wont run. But many do works, like for example, WorldOfGoo (at least on the Pandora), Airline Tycoon Deluxe or new FTL. Many of the GameMaker linux game also runs 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 the TRACE enabled (i.e. dumping to stdout all individual x86 instruction execute, with dump of registers), you'll also need Zydis library accessible on your system.

Some x86 internal opcode use parts of "Realmode X86 Emulator Library", see x86primop.c for copyright details

Here are 3 videos, one of "Airline Tycoon Deluxe" running on an gigahertz OpenPandora, and the other 2 of "Bit.Trip.Runner" and "Neverwinter Night" running on an ODroid XU4.
