Description: Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Currently, Bochs can be compiled to emulate a 386, 486, Pentium/PentiumII/PentiumIII/Pentium4 or x86-64 CPU including optional MMX, SSEx and 3DNow! instructions.
Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS, Windows® 95/98 and Windows® NT/2000/XP or Windows Vista. Bochs was written by Kevin Lawton and is currently maintained by this project.
Bochs can be compiled and used in a variety of modes, some which are still in development. The 'typical' use of bochs is to provide complete x86 PC emulation, including the x86 processor, hardware devices, and memory. This allows you to run OS's and software within the emulator on your workstation, much like you have a machine inside of a machine. For instance, let's say your workstation is a Unix/X11 workstation, but you want to run Win'95 applications. Bochs will allow you to run Win 95 and associated software on your Unix/X11 workstation, displaying a window on your workstation, simulating a monitor on a PC.

Description: Pokas x86 Emulator is an Application-Only emulator created for generic unpacking and testing the antivirus detection algorithms.
This Emulator has many features some of them are:
1. Has an assembler and a disassembler from and to mnemonics.
2. Support adding new APIs and adding the emulation function to them.
3. Support a very powerful debugger that has a parser that parses the condition you give and create a very fast native code that perform the check on this condition.
4. Support seh and support tib, teb, peb and peb_ldr_data.
5. It monitors all the memory writes and log up to 10 previous Eips and saves the last accessed and the last modified place in memory.
6. it support 6 APIs:GetModuleHandleA, LoadLibrayA, GetProcAddress, VirtualAlloc, VirtualFree and VirtualProtect.
7. With all of these it's FREE and open source.

It successfully emulates:
1. UPX
2. FSG
3. MEW
4. Aspack
5. PECompact
6. Morphine

But it does contain bugs and it still in the beta version. It surely will be fixed soon ith the help of your feedback.

It still doesn't support multithreading and doesn't support Linux ELF executables.
It's still working only on windows but the Linux version will be available soon.

you can download it from https://sourceforge.net/projects/x86emu/
