BinEdit is a binary editor that I
developed. This took a lot of hours, but it has plenty of uses. Code or data,
it doesn't matter--it can pick apart a file using a real-mode indexing system.
What can BinEdit do?
Use BinEdit to read any file
of any file format. The program has two main functions: hex editor and
The Hex Editor feature
will open any file in a binary format so that you can view bytes according to
their physical addresses in the file. This supports decimal/hexadecimal
numbering systems, a real-mode segment/offset viewing algorithm, and perfect
1-to-1 write-back capabilities that allow you to change only specific bytes in
a file, without changing the total length of the file. The hex editor supports
both a numeric viewing system and a text viewing system.
The Code Dissembler feature
will analyze any COM or EXE file and conduct a thorough code trace. The code
dissembler uses a nonlinear searching algorithm to locate all branches of code
from existing jumps and calls. It also pastes text labels of each branch it
finds. Currently, the dissembler's focus is real-mode MS-DOS applications and
is therefore limited in accuracy to only the 8086 instruction set.
BinEdit Version 0.9 contains only
the hex editor. Requires only a speck of memory compared to version 1.1. It is
also more robust and less crash-prone than version 1.1.

BinEdit Version 1.1 is a
prototype that contains the code dissembler. It can do everything that version
0.9 can do. It can also dissemble EXE's and COM's. Several bugs from 1.0 have

Many real-mode applications of
the past have been "broken" today for only a single reason: CPU speed
increases. Often, a slowdown utility or emulator can do the trick, but this
doesn't always work. I have always been interested in getting programs to work
that are too fast on modern processors, yet also seem to thwart slowdown
utilities. BinEdit helped me immensely in performing the hack job for BipBop 2.
I am proud to present a patch for
the shareware version of BipBop 2. The reason why slowdown utilities didn't
work, I found out, was this: the delay counter used an internal polling loop, a
HORRIBLE speed control device. The problem with BipBop 2 was that its
real-time delay counter was only 16 bits wide, which made it reach an upper
limit at the number 65535, and consequently run too fast on faster computers.
This patch tweaks it so that the precision is 32 bits. It runs fine on a 350
