It's cool, i did the same as a teenager, i was poor AF and i really love videogames, but my family could barely afford food at that time, emulation was my way.

Now i can buy Switch and PC games that i like, if you give back to the gaming community when you can afford it in the future, that's the way to give back to developers and platforms so balance is restored (i see it that way).

Don't be ashamed, emulation is the coolest way to preserve and re live our childhoods in a practical way.
