I don't support piracy of currently sold games. I support piracy once a developer stops selling their game and obtaining a ROM (and bypassing any implemented DRM) becomes the only feasible way to preserve a game.

Yes emulators are unfortunately often used for pirating games. But they will also be the only way you get to enjoy your purchased games in 10-20 years when the vendor stops producing the hardware, cuts off online services and your device becomes a fancy paperweight either as a consequence of that or naturally.
