Guidelines for inspecting old (circa 1998 - 2007) receiver control and updater software

Image
Old control/updater programs are usually written in VB6, Delphi/C++ Builder or .NET VB, C#. DetectItEasy can show PE32 info which usually and almost allways shows which development tool/framework is used. DetectItEasy strings function shows ASCII strings inside .EXE file. Sometimes there is code embedded inside exe, usually as Motorola S-Record format. E.g. with Python script is easy to extract it and remove unnecessary characters. import re re.sub(r'[^S0-9A-F\r\n]+', '', text) ...  or use Linux stings command.  Installers are usually msi or innoextract. Can be extracted e.g with unzip, msiexec, msiextract (Linux) or innoextract (Linux). Sometimes embedded code is inside in a one of the extracted files. SRecord is a set of tools for inspecting/converting etc. S-Record data. VB6 programs can be further examined e.g. with VB6 decompiler lite. .NET programs, dotPeek can export to VS solution. Even in deobfuscated .NET programs it is possible to find some quite clean code (...

Inspecting a discontinued portable amateur radio memory control program

Image
Detect It Easy   De4dot   dotPeek export to VS project. VS 2026 converted successfully to .NET 4.8 level. Weird and obfuscated source files but also a dir in project that contains clean code files. Changed configuration to x86.   Build failed with many C# 7.3 nullable disable errors. added to .csproj     <Nullable>Enable</Nullable>     <LangVersion>preview</LangVersion> still one CSC nullable disable error c# 7.3 changed to wrong configuration x86 -> x64 and back to x86 then clean and successful build.

Inspecting firmware updater of a old discontinued handheld mobile HAM transceiver

Image
Firmware updater exe : DetectItEasy  De4dot: VS Code ILSpy decompiled cleaned code  dotPeek created VS solution   Firmware ROM binary file inside VS solution, DetectItEasy: CPU is probably R8C. Some Ghidra R8 processor modules exists: https://github.com/silverchris/m16c

Inspecting firmwares of some receivers and transceivers

Image
Some radio scanner firmwares contains lots of debugging strings and code, e.g. debug19 debug20 debug21 . C . sjis MOT TST test_control_ch  and some are based on NORTi RTOS. Some receiver model firmwares are probably encrypted but e.g. binwalk can show something        Some devs have multiple firmwares, e.g. one for the DSP and one for the display.
