Homebrew Backgrounds with extended palette ?

[Ben_j]

I'm using extended palettes for my sprites, and I'd like to use different backgrounds with different palettes as well. The problem is I didn't find anything to tell the background what palette to use.

Here's what I did so far :
CODEvramSetBankH(VRAM_H_LCD);
dmaCopy(alphabgPal, VRAM_H_EXT_PALETTE[0], 512);
dmaCopy(kaossbgPal, VRAM_H_EXT_PALETTE[1], 512);
vramSetBankH(VRAM_H_SUB_BG_EXT_PALETTE);

Then what ? Do I have to use registries or something ?

I think you use oamSet() on each sprite individually to tell what palette it should use

I'm not talking about sprites here. I want extended palettes on backgrounds

Ah, sorry.
Maybe vramSetBankH() should be used before copying. And try to use less ambiguous defines to check the compliance between engines and layers (slots)

VRAM_G_BG_EXT_PALETTE_SLOT23 - maps vram g to main engine background extended palette slot 2 and 3

Looks like the easy way to map entire banks for palettes are macros like VRAM_G_BG_EXT_PALETTE_SLOT01
