Place DMA mio0 compressed character textures in a buffer. Later, this data becomes decompressed.

The player struct tracks the texture indices to load.

Parameters

player
playerId	Player ID.
screenId	Rom buffer index appears to always be 0-3. Sometimes subtracted by 2.
screenId2	Second buffer index appears to always be 0-3.
index	First buffer index always zero.

load_wheel_palette_non_blocking()

void load_wheel_palette_non_blocking	(	UNUSED Player *	player,
		const char *	texture,
		void *	vAddr,
		u16	size )

read data from ROM and write it to the given virtual address

Parameters
