How do I scale the entire game?

I'm making a Game Boy demake and it'd be much simpler if I could work in the "native" resolution of the Game Boy, then scale the exported/previewed game up by 300% if possible. Is this doable in Construct 2/3?

Edit- I found this method: https://www.scirra.com/tutorials/1258/c ... resolution

However it doesn't seem to work in Construct 3.

I think you just have to make your game in the resolution you want and in the project parameters, set "sampling" to "point"

Thanks for the response! I'll play around with it.
