This volcano lotus will fly around with customisable X and Y speed.
If the extra bit is clear, it will fly in the top-left direction. If it's set, it will fly in the bottom-right one. You can also make them oscilate horizontally (extra bit clear) or vertically (extra bit set) based on a define. Finally, you can completely set its X and Y speed with extra bytes, the first one for the Y speed and the second one for the X speed (those will overrite their previous speed).
Usage with NMSTL is recommended. Based on Volcano Lotus dissasembly by Nekoh.
