You can't change the position of the real mouse cursor, but you can control a sprite, emulating mouse movement. There are two methods:
System: Every tick
-> CursorSprite: Set position to
..... X: Self.X + Gamepad.Axis(0,2)×dt×4
..... Y: Self.Y + Gamepad.Axis(0,3)×dt×4
System: Every tick
-> CursorSprite: Set position to
..... X: lerp(Self.X, ((Gamepad.Axis(0,2)+100)÷200)×LayoutWidth, dt×10)
..... Y: lerp(Self.Y, ((Gamepad.Axis(0,3)+100)÷200)×LayoutHeight, dt×10)
