Lunar Jetman: Routine at 34265

34265: Shift Old Sprite Pair

Copy of 34334 for the old sprite. The self-modified jump at XORSpriteLoop_Shift lands in this run of shifts, which push the graphic pair into pixel alignment before it is XORed onto the screen.
ShiftOldSpritePair	34265	ADD HL,HL	Shift the pair left through A.

	34279	EX DE,HL	Switch the shifted pair into DE.
XOR three bytes onto the screen, then move up one pixel.
ShiftOldSpritePair_XOR	34280	EX (SP),HL	XOR A, D and E onto the screen at HL and restore the graphic pointer.
