If you can afford an iPhone and Mac, I would suggest that you can probably stretch to buying a Nintendo Switch. And honestly, it's worth it. Pick up "Breath of the Wild" and start there.
Download a SNES or GBA emulator and play Link to the Past
The emulator? If you really have no other way around to buy/play it, then it is somewhat ethical.
If they weren't going to buy it anyways, it hurts nothing to emulate it.
