Swap magic still requires the use of slider tool/no solder modchip/modchip/flip top cover. See, the problem is that if you press the eject button, it will reinitialize and see you'e not playing an original game.

The slider tool is the least troublesome way, since all you need is to remove the dvd-tray door cover (it clips/unclips, and just two screws to undo/redo).
