| pSrc | Pointer to transfer origin |
| offset | Offset |
| szByte | Transfer size (in bytes) |
None.
This function uses DMA to transfer standard OBJ data to the sub 2D Engine palette OBJ-VRAM. An offset can be specified for the transfer destination address. The DMA channel that is used is GX_DMAID (defined in gxcommon.h). The transfer destination address is HW_DB_OBJ_VRAM in the ARM9 memory space + offset. Both offset and szByte must be multiples of 4.
Notes: Because the DMA transfer is carried out internally, the transfer source data must be flushed to the main memory using a function such as DC_FlushRange prior to the process. If the regions for transfer source and transfer destination overlap, the operation result is not guaranteed.
