In A New Hope, the original Holotrainer was an extremely large block with a door, when Micro-Ice entered, Clamp programmed a scenario and Micro-Ice found himself standing on a pitch, floating in an endless sky. By the hour Aarch Academy had been made in Akillian Stadium, Clamp had managed to perfect the device so that young players had to stand on a square on the ground and large pixels would float down from the ceiling and envelop them in a large cube. The device was made portable as it was used within Genesis Stadium.
