Hi, everyone.

I'm pretty confused about programming the Casio Prizm.

I successfully compiled the Hello World test program, but I can't really do more than that. I'm pretty much a noob at pointers in C.

~~How exactly do I plot a pixel to the screen? I know that vram is at 0xA8000000. How do I make a pointer to it and copy a color~~
What is the format of the 16-bit colors?

Thank you so much for helping me.

EDIT: Alright. I managed to plot pixels on the screen. Is there a way of disabling the annoying border?

5 bits red, 6 bits green and 5 bits blue.

I think it's advanced coding or something. You might want to set it to black or the same as background color.

Use directDrawRect.
