Vram I Sub Spr Ext Pal

[Flow]

Code: Select all

/** \brief  Allowed VRAM bank I modes */
typedef enum {
	VRAM_I_LCD                    = 0,
	VRAM_I_SUB_BG_0x06208000       = 1,
	VRAM_I_SUB_SPRITE             = 2,
	VRAM_I_SUB_SPRITE_EXT_PALETTE = 3,
}VRAM_I_TYPE;


/** \brief  an array of 256 15-bit RGB values*/
typedef u16 _palette[256];

/** \brief  An array of 16 256-color palettes */
typedef _palette _ext_palette[16];

/** \brief  Used for accessing vram E as an external palette */
#define VRAM_E_EXT_PALETTE ((_palette *)VRAM_E)

/** \brief  Used for accessing vram F as an external palette */
#define VRAM_F_EXT_PALETTE ((_palette *)VRAM_F)

/** \brief  Used for accessing _palette G as an external palette */
#define VRAM_G_EXT_PALETTE ((_palette *)VRAM_G)

/** \brief  Used for accessing vram H as an external palette */
#define VRAM_H_EXT_PALETTE ((_palette *)VRAM_H)

So I was going to set Vram bank I as 'VRAM_I_SUB_SPRITE_EXT_PALETTE' but noticed that there was no reference to a VRAM_I_EXT_PALETTE and was wondering if this was just an omission or if Vram I can't really be used that way?

The hope was to be able to do something like this:

Code: Select all

vramSetBankI(VRAM_I_LCD);
dmaCopy(spritePal, &VRAM_I_EXT_PALETTE[i], 512);
vramSetBankI(VRAM_I_SUB_SPRITE_EXT_PALETTE);

or is that a terrible way to do Ext palettes cause I couldn't find any other way to do it?

Thanks for all the hard work and help!

I'm fairly certain you have this correct. Besides this, you'd just have to enable extended palettes for sprites in the Display Control.
