box86 - v0.3.6 Latest Release

Published by ptitSeb 5 months ago

What's Changed

=> Speedup dynarec, and allow the use of BIGBLOCK 2 or 3 combined with CALLRET on more software

  • Wrapping: More libs and function wrapping (gtk3, vulkan...)
  • Reworked X11 Callback handling, for better stability
  • Reworked exit and the load/unload of libs
  • Some more profiles in box86rc
  • More SSE3+ opcodes in dynarec
  • Better way to rename executable (including wine ones) so driver like mesa can apply the correct profile
  • Better handling of the Hardware Counter and TSC emulation
  • Reworked memory managment in the Dynarec, limiting amount of dynamic allocation
  • PageSize detection and handling dynamic. Larger than 4K pagesize will be handled automaticaly.
  • Lots of improvments in x87 handling (virtual stack, rounding, ffree, etc.)

  • Added specific suppport for RK3588 board (needed some hack in signal handling, probably due to the use of a non mainlined kernel)

box86 - v0.0.2

Published by ptitSeb almost 3 years ago

  • A full commercial games runs fine on the Pandora platform: Airline Tycoon Deluxe.
  • Implemented all planned subparts of Box86 except JIT support.
  • CPU Emulation is at roughly 75%. This includes x87 and SSE/SSE2. MMX is barely implemented (but barely used anyway).
  • x87 emulation is simplified, no real x87 State handling (but should not be mandatory, as the native libm library is used)
  • No Signal handling yet
  • ELF Loader is crude and probably full of bugs. Also, the initialisation of libraries are defered after all symbols are resolved for now.
  • Wrapped libraries include libc, libm, rt, pthread, libdl, dllinux, libasound, GL, GLU, SDL1/mixer/image, SDL2/mixer/image/smpeg, OpenAL/ALUT, libz, libpng16, vorbisfile, x11/xrandr/xxf86vm.
  • Most wrapped libraries are still partially implemented ( the SDL1 & GL libraries should be complete).
  • Implemented specific mecanism for SDL(1/2) RWops, to be able to used them both in Native and x86 world.
  • WorldOfGoo works, but is painfully slow on the Pandora platform (there is too much double math, and lack of JIT).
  • FTL works, but sound is broken (issue with thread? asound? or CPU core?)
  • Limbo launches but crashes before main menu.

Full Changelog: https://github.com/ptitSeb/box86/commits/v0.0.2

box86 - v0.0.4

Published by ptitSeb almost 3 years ago

  • Improved the initialisation of dependent libraries. More things work now.
  • Added a lot of wrapped functions.
  • Added a few wrapped libraries (like libz or some other x11 related library).
  • For trace enabled build, Trace can be enabled only after a certain amount of opcodes (still, a debugger would be better).
  • Some fixes in a few opcodes, and implemented x87 rounding (SuperMeatBoy behaves better now).
  • FTL 1.6.9 still has corrupted music, but older 1.5.13 seems fine (different set of libraries).
box86 - v0.1.0

Published by ptitSeb almost 3 years ago

What's Changed

  • Dynarec!!! Only for ARM (note that Dynarec doesn't support JITed code for now).
  • Added real support for getcontext/set/context/makecontext/swapcontext.
  • Preliminary signal handling.
  • Fixes to SDL(1/2) Image and SDL1 Mixer, and to SDL1.2 RWops usage.
  • Fixed numerous issues in opcodes (both interpretor and dynarec). FTL works fine now, among many others.
  • Added wrapped GTK support (still ongoing, many libraries involved).
  • Make loading of libraries more configurable.
  • If a wrapped native library is not found, try to use an emulated one.
  • Added an env. var. to force the use of emulated libraries for certain libraries.
  • Added an env. var. to precise which libGL to use.
  • Added Install / Uninstall target (using systemd binfmt).
  • Added more hardware targets (RPis, GameShell...).
  • Wrapped more libraries (including FreeType, smpeg, ncurses, sndfile...).

box86 - v0.1.2

Published by ptitSeb almost 3 years ago

What's Changed

  • The Dynarec now handle JIT code
  • Added support for Unity games (not perfect yet).
  • Added support for Wine (not perfect yet). You need an x86 build of Wine to use it.
  • Added support for Steam (not perfect yet). Note that Steam have limited functionalities on 32bits (only mini-mode is available).
  • More wrapped libs
  • Added support for the "PltResolver". This makes the order of libraries less important and many symbols are now resolved at runtime.
  • Added an option to build Box86 as a library (to wrap dynamic library).
  • Better Signal handling (not perfect yet).
  • More opcodes added, more opcode fixes.
  • More Dynarec opcodes.
  • Added support for FS:, and creating custom selector (needed by Wine).
  • There is now 1 x86emu_t structure per thread (simplifying/optimising many callback handling).
  • Box86 now has a logo!
  • Added options handling (only version and help for now). Now it's much usefull exept for version printing.
