Yeah, whenever I use one of the [ON] key combinations, it destroys DCS's homerun hook. Also, this version's [ON] + [VARS] seems to be a bit unstable (cause a ram clear sometimes).

Yeah, I couldn't get that glitch to work. It's kind of similar to the weird fraction glitch nobody could replicate. :\
IIRC, Wabbit does not emulate BSOD.

* ralphdspam waves to Waave Good luck with the BASIC and Axe coding.  Have some peanuts:

Zeda, I moved your routine to its own dedicated TypeWith.me page.  http://typewith.me/V0lEvy11lcI also updated my first post with your link and the updated code.

Thanks! I will try this later.  EDIT: I found out that AND can take imm 8 values! Saved myself a couple of bytes.

Can you add a key combination to run an app/pgrm of choice? (like DCS's ON + App)

Welcome back! I'm glad to see that this has been all sorted out.

It can be cumbersome to store all of your 16 bit pointers to ram, though. On the other hand, the 6502 takes less T-States per instruction. (Then again, you have to make more ram stores/reads.) I also should learn x86. I don't really know what to do with the extra 24 bits, though.

Wow! Looks great! Stop making epic programs. Give someone else a chance

Hmm... It's been 6 hours, right? (This can also probably count as an update too.) Here is the current routine: EDIT: See above.

Ah, I like the hi-lighting and searching. Can you, by any chance add T-states?

That looks really nice!

Nice! Fore some reason, I like to mess around with old computers.

Hi, I just made this 4*4 sprite routine aligned to a 16*24 (half pixel) grid. Can anyone help with optimizations or suggestions? http://typewith.me/BSgvbUFXDh;==========
;XOR 4*4
;==========
;Inputs:
;ix = sprite address
;c = X Position
;b = Y Position
;Outputs:
;a = last line of sprite displayed
;b = 0
;c = X position (undestroyed ^^)
;de = 12
;hl = buffer location of sprite + 12 (next line)
;ix = sprite address + 2 (next sprite?)
;==========
;This was made to be a standalone program.
#ifdef bcall(xxxx)
;THE GAME
#else
#include "ti83plus.inc"
.org $9d93
.db t2ByteTok, tAsmCmp
#endif
;==========
;Just for testing purposes:
bcall(_clrlcdfull)
bcall(_runindicoff)
bcall(_grbufclr)
ld ix, x4sprite ;ix holds sprite address
ld c, 1 ;c holds X location
ld b, 1 ;b holds Y location
;==========
FourXOR:
ld a, b
add a, a ;\A * 3
add a, b ;/
add a, a ;\A * 4
add a, a ;/
ld h, 0 ;A*2 is too large to fit into 8 bits, so we must use a 16 bit register.
ld l, a
add hl, hl ;\A * 4
add hl, hl ;/Align Y pos to the X4 grid.
ld d, 0
ld e, c
srl e ;Now, we are only concerned on the X8 alignment. We will fine tune it to X4 later.
add hl, de ;add X pos to Y pos
ld de, plotsscreen ;Finally, we add the Buffer location.
add hl, de
ld b, 2 ;B*2 Pixels tall sprite
ld e, 12 ;Width of Screen
_FourDispByte:
ld a, (ix) ;loads sprite at ix
and %11110000 ;use left side of byte
bit 0, c ;If X pos is an odd number, we have to shift to the right.
jr z, _FourDispN1 ;if D is aligned to the byte, branch. Else, shift sprite by 4.
srl a ;shift sprite to the right 4 pixels.
srl a
srl a
srl a
_FourDispN1:
ld d, (hl)
xor d ;xor sprite onto current buffer contents
ld (hl), a
ld d, 0 ;DE = 12
add hl, de ;shift pen down one row
ld a, (ix)
and %00001111 ;It is on the right side of the byte.
bit 0, c
jr nz, _FourDispN2 ;if d is not aligned to the byte, branch.
add a, a ;shift sprite to the left 4 pixels
add a, a
add a, a
add a, a
_FourDispN2:
ld d, (hl)
xor d ;xor sprite onto current buffer contents
ld (hl), a
inc ix
ld d, 0
add hl, de
djnz _FourDispByte
;==========
;More pseudo random stuff just for testing
bcall(_grbufcpy)
bcall(_getkey)
;==========
ret
X4Sprite:
.db %10010110
.db %01101001Also, Zeda's routines can be found here: http://typewith.me/V0lEvy11lcRuner112's routine: http://typewith.me/Zv15SUf9VeThanks.
