As the title says, I'd like to know if I can create a DLL for Petka, and how I would do it? I want to create a .dll like EtLdrOnline.dll and integrate it into the program with my own settings.
New DLL files must be called by the program (PETKA), and PETKA itself must also be extended so that your extensions can be read and stored in variables, which can then be passed to the relevant queries.
You're probably confusing *.ini files with DLL files, but even with *.ini files, the program (PETKA) needs to be modified so that this information can be read and passed.
