Title Doublewide masked/unmasked sprite routine
Description Includes bitshift.inc, my include file for 16-bit bitshifting for all three 16-bit registers, boolean.inc, which contains routines for running a bitwise boolean on hl with de or bc, and doublesprite.inc, which contains my routine for displaying a 16-bit sprite (the usual size is 8-bit) on the screen. The routine is in XOR logic, but can be changed to AND, or OR logic. Refer to readme.txt for info on input registers for the sprite routine. Now also includes doublemaskedsprite.inc, which is my sprite routine for a 16-bit masked sprite. I've also updated to old sprite routine to be much faster, and doesn't use IY, and i made some of the bitshifting routines faster.
