The CGRAM DMA Transfer Style Table stores miscellaneous parameters for DMA transfers to CGRAM.

Format

Unknown

Length: 2 bytes (0x2)
Offset within entry: 0x00
Range of values: ??

Number of Bytes to Transfer

Length: 2 bytes (0x2)
Offset within entry: 0x02
Range of values: 0x0001-0x0200

Number of bytes to DMA transfer to CGRAM. At most 512 (0x0200), the maximum size of SNES CGRAM.

Source Address

Length: 2 bytes (0x2)
Offset within entry: 0x04
Range of values: 0x0000-0x1fff or 0x8000-0xffff

Source address (in the CPU address space) for the DMA transfer. EarthBound always sets the source bank to $00, therefore the source address can only be $000000-$001fff for WRAM or $008000-$00ffff for ROM.

Destination Address

Length: 2 bytes (0x2)
Offset within entry: 0x06
Range of values: 0x0000-0x00ff

Destination address (in CGRAM). CGRAM is addressed by word (color), not byte.
