[pokecrystal] Drawing Data to the Screen

[PinkAmpharos]

I've been working on a GBC hack with the Polished Crystal engine (Currently titled something like Pokemon Legends Celebi).

Without further ado, here's my question:

So I've been making a custom title screen and I'm a little confused as to how sprites are drawn to the screen. Is there any documentation for drawing data to the GBC screen? After looking at the title screen code, it looks like I'll need to write my own sprite drawing call, and I was wondering if there were any code snippets or resources worth looking at before I get started.

I was already able to modify the stuff for the Title drawing to get a larger logo, like this (Now including the "Legends" text):


I also got the Crystal to disappear by removing the Crystal initialize code (though that seems kind of sketchy and probably not good).

My goal now is to display this underneath:


Thanks in advance :)
