Hope, there are some people who need a tool like this. I hope that this product will be a help for you. Today’s programmer even doesn’t know assembler language – and doesn’t need to know it. People work with GUIs, write in C++ (IDA is written in C++ too, about 40000 lines) they adore VisualBasic and they debug in source codes. I really think that disassemblers and all the staff like this are becoming obsolete. Today I would implement something based on client-server architecture with network support (I have a crazy idea about X-windows implementation) working under various operating systems – but I won’t. It was time to learn more about other computers, networks and other nice things. In July 1991 I stopped working at IDA almost completely, working at IDA only for fun. I wanted to create a built-in C-style language to control analysis of the program, to add more processors, to disassemble object files, to handle UNIX COFF files, to add more intelligence to IDA e t c…Īlas, all of this was not implemented. In April 1991 the first program was fully disassembled with IDA.
IDA STARTER VS IDA PRO CODE
In the beginning of 1991, in January, first code line was written.

It took half an year to screw up enough courage and to start implementing it. Ilfak Guilfanov (from IDA 2.05 history file, circa 1994?):įirst idea about IDA was born in the fall of 1990. However, it took time for this approach to be appreciated by the users. The database saved all changes so the work could be performed incrementally over time. Renaming and commenting was done “just in time” instead of redoing the whole disassembly on every change. It could disassemble a file piece by piece, loading only the fragment which the user was looking at, and did not need to load the whole file into memory. There were some debuggers which could be used for disassembly but they did not really offer RE features such as custom names or comments so deep RE was often done in a text editor or by marking up printouts. Most of the runtime data was kept in memory (at most 640KB in DOS) so it could fail on big files. After each change to the definition file the disassembly of the whole file had to be redone from scratch which could take a long time on the machines available at the time. It had limited interactivity in that it accepted a “definition file” with a list of starting disassembly points, possible function names and segmentation info. The most popular (and expensive) one was Sourcer by V Communications.

Aside from debuggers, disassemblers were mostly batch based (non-interactive).
IDA STARTER VS IDA PRO SOFTWARE
However, software development industry was growing quickly and there was a need for debugging and diagnostic tools.
IDA STARTER VS IDA PRO PC
Typical PC had at most 1MB of RAM leaving little space for intensive tasks. In the early 1990’s, DOS was the most popular OS for PCs which were majorly 8086 with occasional 80286 (80386 was still very expensive). In commemoration of the anniversary we’ll describe the beginnings and major milestones of the epic journey.
