Well, yes, I am just about out of CPU time in my kernel, but I don't
the game is a good candidate for the paddle at any rate.  If you think
the physics of a gun such as this, paddle movement is very UNrealistic.
With a real gun, it would take time to move the gun from side to side,
paddle movement it would be WAY too easy.  Half of the difficulty of the
game is trying to not get in a position where your gun is on one side
it is absolutely needed on the other.  Imagine Space Invaders using
paddles, it would have ruined the game.  BTW, though you say the game is
too hard - think about how long you've played it!  I can keep playing it
as it is indefinately, it takes practice!  Also, remember that I don't
ANY level design at all in there, just object movement and interaction.

Yes, you are right to a point here.  I'm not done with the graphics
the graphics you see are there just quick mock ups, though I think the
paratrooper and helicopter are close.  If you notice, though, the
and the plane are double width sprites, the only limitation is that the
minimum width a sprite can be is 8 pixels.  I will see about changing

It will be designed to MINIMIZE this, but the whole point of my kernel
to allow freedom of movement.  The maximum flicker possible on this is
and THAT would be very rare, since I allow 6 copies of player 0, but the
copy is always an explosion something would have to get blown up and
a new sprite would have to appear before the explosion disappears, so
realistically it can go to 12hz, and that too is very rare.  Try it on a
real Supercharger, it looks far better than on the emulators.
