Make "Slave of the VU" work.

Implemented VU instructions MADDAi, MSUBi, MULA, MADDA and MADD.
Fixed a little bug with LOI. This scene uses antialiased lines to render itself. On the PS2, the anti-alisaing process seems to be tightly coupled with the alpha blending process. If I also check the picture on this site, the lines seem to blended using an additive formula. An additive formula is set prior to rendering the lines when executing the demo. So, I decided to enable alpha blending when antialiasing is enabled in the renderer. This is the result: 
Again, I don't really know if it gives the right thing, but it seems similar to the only screenshot I've seen of this demo. Speed wise, it seems to do better than the first scene at the beginning, but as the number of lines grow, the thing becomes slower and slower... Tomorrow, I'll check if I can execute the last scene of this demo. |
