Hello,
I'm Delphi developer with more than 15 years experience with it.
And as you know Delphi compile code to native machine language, so it's impossible to reverse it's code to original Delphi code, you can only get resources, such as forms, strings, and functions names, forms name, but functions code will only return as assembly.
If you can provide me with the executable file, I will try to give you some info about what could be done with it.
Regards,
Mohammed
