Now, I've removed the 8bit layer and am trying to put a print Console on a layer above the 16 bit one, 0 in this case. There are a handful of problems, but I think I'm close. EDIT - I have looked at the post a little bit down from here and tried to use it as a reference since it's pretty much the same scenario (I'm using 2 VRAM banks though...) but it didn't help much...
1. If I put up text before loading the background's graphics, that text is not shown.
2. Text displayed afterward shows up, but there are artifact characters elsewhere on the screen.
3. Clearing the console (Pressing and releasing A button) and trying to display more text results in a blue horizontal bar across
the top of the screen and more text is displayed successfully. The other artifacts are gone. I've had varying results as I've tried to get the right
mapbase and tilebase values. If I understand correctly... I need to get those into VRAM_B, so the mapbase must be 64 or higher and the tilebase 8 or higher. Outputting the gfx location (as long as I'm doing even that part right) seems to verify my assumption, but still... the results aren't quite right.
4. Here's the code as it stands. The only compiler warning is the output of bgGetGfxPtr(topScreen.bgId) which it says is a u16 ** when it expects an unsigned int. I couldn't seem to get that to cast down right... but it still shows outputs what I expect to see.
