I'm thinking of emulating a game I never purchased before
Why would you emulated a game you never purchased before?
I don't think emulation is wrong, I just want to have fun.
You are wrong to think you don't have to buy a game, it's wrong to steal someone's intellectual property. If nobody purchased games they would run out of resources to make games.
WTF, I can't believe you're supporting a corporation. Whose side are you on?
I am on the side of doing things that are legal. Stealing a game without paying for it is illegal and you could end up in big trouble if you are found out. Don't you think you will feel better playing your game when you know that you obtained it legally?
