• I guess it's what would get if you connected together a mandelbrot generator running on a 486dx50, a demo effect generator randomly picking up every effect made in the 20 last years, the whole seen through a lavalamp accelerated 3d screen with an Amiga overlaying 2d pictures.
  
  For some strange reasons the whole make sense after you watched it twice, which is fine because if you don't quite you are going to watch it twice.

• Me like it.
  Nice work on 2d vector overlays, the bullet scroller is cool as well, and the star-stars is fancy :)

• Great code, but really the visuals and the music is just painful.

• What I call 3V mode is when you double buffer the DMA queues, and when the PVR side is also double buffering the TA data. By doing that you almost never have to stall the render for graphic primitives to arrive, and you don't have to wait either for the DMA to be done before you send data for the next frame.
  
  Concerning the optimization, I found out that in my case I was slowed down by the DMA transfert, not by the CPU or by the PVR itself.
  
  One of the big improvement I got was when I stopped using the hardware culling and instead do the visibility testing myself. By doing that I managed to write/send about 1/3rd less primitives to the DMA. I also had to do the near clipping of my stripes (in a game you can't really control what the user's doing), so I needed all the CPU I could, so yeah saving cycles when transforming was kind of important :)
  
  (For the landscape I even did 2d "cone of vision" clipping to limit even more the amount of stuff to send to the dma)
  
  About GCC I don't know, never used it. It's not that trivial to optimize for the SH4, things like immediate values being stored as pc relative data chunks you have to jump over is not that a common architecture :D
