DS development > 2 Questions about the VRAM

#122166 - Robthar - Sat Mar 17, 2007 3:09 pm

1. Is the Video RAM unused when not set as used RAM?
2. Could I use the 128K Ram from E-H combined?

1) Yes.
2) Depends what you want to use it for.

Wherefor are the other Rams used?
I would like to add 2 Backbuffers a 24bit, there exactly 384k fron VRAMC to the last Vram, but when they're used I will have to do it another way ._.

Code:

   while(true){
      for(int i=0;i<0x60000;++i){
         printf("%d",VRAM_C[i]);
      }
   }
