8086 Disassembler PATCHED Download Programs
Please note that this code was written when i was trying to learn C++, so it is not a very well commented code, but dont hesitate to download and have a look - i have added quite a few comments at very important places and that should help you. If you already have a good knowledge of decompilation and the 8086 assembly language, then it would be a breeze for you!
8086 disassembler download programs
This gets to the other sense of your query: "I want to make a disassembler". The source for ndisasm is available, and it handles many of the descendants of 8086, not just 8086, itself (which seriously clutters it, if all you want is an 8086 or even 80386 disassembler), but it is not self-contained and has a heavy dependency on the rest of the distribution.
And then you've just disassembled a disassembler that also happens to do CPU emulation, like Fake86 does - but only for the 8086. You'll have to make the absolute addresses relative (using the original relocation table as a guide), to make is re-assemblable. Once you do that, you can work on the source. The opcode table is in clear view (if you display it as text) - both when seen in the packed and unpacked versions of debug.exe.
I might port the DAS disassembler to the x86, since items (a)-(f) are already incorporated into DAS's design. I've only ever ported it to the 8051, 6800, 6809 and 8080/8085 (and Z80) up to now; but the transition from 8085 to 8086 is relatively small. To that end, I might hack something out of Fake86. That's mostly abandonware, now, since the author replaced it by XTulator, as Fake86 was written when the programmer was relatively new to C. You might also be able to hack something directly out of DosDebug's opcode tables (their "instr.*" files).
Emu8086 is an 8086 microprocessor emulator and disassembler.It permit to assemble, emulate and debug 8086 programs (16bit/DOS).Although this program was made for Windows, it works fine on GNU/Linux (with the help of Wine).

It's operationis controlled by a command file, which tells it what binary code imagefile(s) to load, the addresses for code entry points such as RST, NMI,etc. (optional), and the addresses for any code or subroutines whichmay not be explicitly called within the MC6800/6802 code. The programthen processes the code, tracing execution paths and identifying jumplocations, subroutines and data tables. The program output is normallyin "list" format, with an address column at the start of each line,however, this address column is omitted if the specified output filename ends in ".ASM".

Based on Intel's iammx.inc file, I managed to create a new set of macros using Ideal programming mode. I have also included an example on how to use them and how they are transparent. The example is MSDOS based and I did not include a pre-compiled version, instead, I included a makefile for easy creation. The example uses case-sensitivity compilation but the macros will work well without it. This is still a beta release. I expect to have some bugs even if I tested every instructions.

This is a minor modification of Cyborg's PMODE for NASM. The onlydifference is that you can now separatly compile PMODE.ASM and othermodules and then link them together using TLINK or some other linker.Note that the CODEEND macro at the end of the main module of a user'sprogram isn't needed any longer. Also included with this release arelibs from the original PMODE 2.4 by Tran.
