Eighty-Six Sprites [was "Sixty-Nine" Sprites]

[RevEng]

My pleasure! I didn't know that about the Jaguar... the Maria design started out as a co-processor for gcc's aborted "spring" ibm pc compatible. I always wondered what that would have looked like, so it's cool to hear that some of the ideas did make it to a more powerful platform.

Jaguar branches and objects are almost this same as Maria DLL an DL

The 7800 is such a weird system.

Great demo rev! Keep.pushing!

 

Reminds me of some remark made in one of the Rikki and Vikki threads where someone said the backgrounds were black by necessity. Absolute statements really bother me.

You need remember that Maria is similar to Jaguar Object Processor 

Screen is made by objects and branches (zones for Maria)

Improving Maria's bandwidth isn't really feasible without replacing her. What Rikki & Vikki does instead is to only use 4-Byte (normal) Display Lists and attempts to combine multiple tiles into larger draws when their pertinent textures are sequential in memory and they all share a palette. If you've ever wondered why the game can stutter for two frames when you're tossing boxes around, this is why. The background manager has to unroll the new tile strips into Display Lists on any changes to the stage geometry.
