Understanding DPRAM

[VectorWorlds]

Hello Bob,

I was wondering if you could help me understand a little more about what could be consuming the DPRAM.  I assumed the DPRAM only contained the drawlist and if I ran a ClearScreen command this would clear the drawlist and free up all the DPRAM.  However this doesn't seem to be the case so I was wondering what else fills up the DPRAM?

Finally is there a way to completely clear the DPRAM.  This could be really useful.  For example I have a hi score screen which I show, then I flip to another screen.  It seems even after removing the sprites and performing a ClearScreen the memory isnt cleared when I flip between these two screens.


Thanks,


Andrew
