void GXS_LoadBG3Bmp (const void *pSrc, u32 offset, u32 szByte);

Description

For 256-color bitmap BGs and direct color bitmap BGs this function DMA transfers bitmap data to the BG3 screen base address in the BG-VRAM of the sub-2D engine. You can specify an offset in the address of the transfer destination. The DMA channel used is GX_DMAID (defined in gxcommon.h). offset and szByte need to be multiples of 2. The transfer destination address is (u32) G2_GetBG3ScrPtr() + offset. GX_LoadBG3Scr is called internally.
