Using the Demo

START exits the test.

The Control Stick rotates the textured box. The C Stick changes the scale of the box.

The B Button toggles the TEV mode (for checking the alpha map).

The A Button resets the scale and angle of the box.

The L and R Buttons change the TPL file shown. (The following is the list of TPL files that can be previewed.)
