| There's just a little bit missing: you don't modify the memory. After xor (hl) you need to put ld (hl),a. |

YEAH!!!!  
You were right, i put that in, so now the code looks like this
Code:
.nolist
#define end .end
#define END .end
#define equ .equ
#define EQU .equ
#include "include/ti83plus.inc"
.list
.org userMem-2;Define where to start in memory
.db $BB,$6D;AsmPrgm instruction
bcall(_clrLCDfull)
ld a,2
ld l,2
ld ix,mouse1
ld e,l
ld h,0
ld d,h
add hl,de
add hl,de
add hl,hl
add hl,hl
ld e,a
add hl,de
ld de,plotsscreen
add hl,de
ld b,8
put8by8loop:
ld a,(ix)
xor (hl)
ld (hl),a
inc ix
ld de,12
add hl,de
djnz put8by8loop
bcall(_grbufcpy)
bcall(_getKey)
ret;Exit program
mouse1:
.db %10000000
.db %11100000
.db %11111000
.db %11111100
.db %11111110
.db %00010000
.db %00011000
.db %00001000
.end
.end
And it worked great. |

I said it befor, and I'll say it again:
change
Code:
put8by8loop:
ld a,(ix)
xor (hl)
ld (hl),a
inc ix
ld de,12
add hl,de
djnz put8by8loop
to
Code:
ld de,12
put8by8loop:
ld a,(ix)
xor (hl)
ld (hl),a
inc ix
add hl,de
djnz put8by8loop
...because you're loading 12 into DE 7 unnecessary times after the first one. This eats up 70 clockcycles. I know it's not much considering an 83+ will compute about 6000 cycles a second, but it's still redundant effort. |

| Hey Thanks CoBB. I typed the source from my head and missed that one line. Also I was tired when I wrote it up so I wasn't thinking about that extra clock cycle usage on the ld de,12 . I've been gone for the last two days so I didn't get a chance to fix it. |

| is it possible to make a sprite move by itself? Like when you run the program, you see a short animation appear and then the program ends, the sprite would move on a designated path. |

| how would I display a sprite on the graph buffer, because the routine displays the sprite on the hoemscreen not the graph and I want it on the graphscreen. |
