different sized sound / shared region (or the mem map needs more alterations?)
fix comms so it boots, it's a bit of a hack for hyperduel at the moment ;-)

                                    Blitter

    [ Registers ]

        Offset:     Value:

        0.l         Destination Tilemap      (1,2,3)
        4.l         Blitter Data Address     (byte offset into the gfx ROMs)
        8.l         Destination Address << 7 (byte offset into the tilemap)

        The Blitter reads a byte and looks at the most significative
        bits for the opcode, while the remaining bits define a value
        (usually how many bytes to write). The opcode byte may be
        followed by a number of other bytes:

            76------            Opcode
            --543210            N
            (at most N+1 bytes follow)


        The blitter is designed to write every other byte (e.g. it
        writes a byte and skips the next). Hence 2 blits are needed
        to fill a tilemap (first even, then odd addresses)

    [ Opcodes ]

            0       Copy the following N+1 bytes. If the whole byte
                    is $00: stop and generate an IRQ

            1       Fill N+1 bytes with a sequence, starting with
                    the  value in the following byte

            2       Fill N+1 bytes with the value in the following
                    byte

            3       Skip N+1 bytes. If the whole byte is $C0:
                    skip to the next row of the tilemap (+0x200 bytes)
                    but preserve the column passed at the start of the
                    blit (destination address % 0x200)
