The digital version is a Game Boy rom so it can be run on pc using something called an emulator. It requires opening the emulator first and then opening the rom file kind of like when you open a text document in a word editing program if that makes sense? It's pretty easy once you try it.
You can try a simple free Gameboy emulator called Sameboy: https://sameboy.github.io/downloads/
One thing to remember is that you need to set up your buttons so you will need to open the menu and go to 'input' or 'controls' or 'key bindings' (I forget what they call it) and assign each game boy button to a button on a keyboard or controller. After that you're good to go!
