I'm trying the different SDK's for Prizm, and found no way to use the 396*224 dots of the screen.
Is anyone know how to get complet screen access?
Also, where can I find some informations on the VRAM ? (difference between 0xA8000000 and 0x88000000, size of buffer, way to copy VRAM to DD manually ...)
EDIT: I saw syscalls 0x02A4 and 0x02AA that allow to choose the frame color.
So, according to my research, I concluded we need to write an other Bdisp_PutDisp_DD to use a 396*224 VRAM. I'll search on this way.
