Emulator question

Hello all, I am building a computer for a friend. One request if I can do it is find an old game that he used to play a long time ago. I found the game online. It was an old Commodore 64 game called injured engine. I downloaded the zip file. after unzipping it, the extension ends ".d64". I have downloaded the commodore emulator from the software manager. Now I am lost. Nothing happens when I select "commodore 64" from the menu. What am I missing? Thanks in advance.

Okay, I used the terminal. Am unsure if i got the basic, kernal, chargen. Would I need to use "sudo" before each command? I used sudo upon starting the terminal. This is what is displayed upon x64 startup.

When I try to run the game, I get an error on the emulator screen.

S?

Would that be because the 3 files didn't get copied and changed? Thanks
