thank yours Miker00lz and Jacob Roman !
very good tips to start with emulators.
if i am if I knew how to do, if i am if I knew another programming language i would translate Emulators in GITHUB from C#, C++ and others to VB6.0.
then I would study the code to create my own emulators.

I wish is to be able to add more features to emulators and games and be able to work on the .ROM files of the games and not have to create emulators
