Lets rewrite this to:

InitLinkMovementBuffer::
	ld a, [rSVBK]
	push af
	ld a, BANK(wLinkMovementSendRingBuffer)
	ld [rSVBK], a

	ld hl, wLinkMovementSendTailPointer
	ld de, wLinkMovementSendRingBuffer
	ld a, d
	ld [hli], a
	ld a, e
	ld [hli], a
	
	; wLinkMovementSendHeadPointer
	inc de ; wLinkMovementReceiveRingBuffer + 1
	ld a, d
	ld [hli], a
	ld a, e
	ld [hl], a

	ld hl, wLinkMovementReceiveTailPointer
	ld de, wLinkMovementReceiveRingBuffer
	ld a, d
	ld [hli], a
	ld a, e
	ld [hli], a

	; wLinkMovementSendReceivePointer
	inc de ; wLinkMovementReceiveRingBuffer + 1
	ld a, d
	ld [hli], a
	ld a, e
	ld [hl], a

	pop af
	ld [rSVBK], a
	ret
