Does anyone know a fast routine for dividing two unsigned 16-bit registers?
Hehe, I offered on the previous page  div_hl_de:
; BC = HL/DE, HL = remainder
ld a,h
ld b,l
ld hl,0
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
ld c,a
ld a,b
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
scf \ rla \ adc hl,hl \ sbc hl,de \ jr nc,$+4 \ add hl,de \ dec a
ld b,a
retNote: Code is untested, so tell me if there are problems

With string parsing you should include an "escape character" like in most programming languages, so you can put quotes and sto (or even raw characters inputted as hex) into strings without hassle.

Nice job man! I've never been able to get past the planning stage for anything like this  Edit: I'll be glad to write multiplication and division routines if you need me to Edit3: Removed Edit2 for stupidity

My computer asks me when I plug something into the microphone port whether it's used as a mic or a line in. Could just be my computer though.

here is a little package I made to make assembly easier
it includes Spasm2, ti83Plus.inc, and a bat file to make assembling easier.
tell me what you think
Cool!  Just a note, looking at the batch file, it appears to only take *.asm files. Maybe it would be good to include *.z80 too.

(about calc84's post yesterday):
shouldn't that be:
ld b,6
call irandom
inc a
(I didn't know irandom could take an upper bound, which explains my 'strange' way of working)
I'm pretty sure irandom generates a random number from 0 to B-1.

ld hl,plotsscreen ;copy from here
ld (hl),0 ;write first byte
ld de,plotsscreen+1 ;copy to here
ld bc,768-1 ;copy all but the first byte
ldir
Note, LDIR basically does this:
Loads value at (HL) to (DE)
Increases HL and DE
Decreases BC
If BC is not zero, rinse and repeat
Since in this case DE is the address directly in front of HL, the 0 gets copied to all the bytes in the buffer.

Have you ever heard of Netham45?
I have.
Where did you hear about Netham45?
On facebook.
Really? What's his name?
Frank. Edit: What is the current year?
I already told you, it's 2005.

Okay, after further use, I think it is fully a bot.

Like I said, short conversations. Fairly often, it will switch you to chat with a different user (thus the sudden topic changes).
No offense meant, but did you consider that maybe it just has no idea what it's talking about? Something to consider is that website has few ads up, I doubt that the website makes enough money to keep people making conversations like that all day
By "user" I meant people like you and me (which there seem to be plenty of)

I'm convinced that this "learning from conversations" means that it puts you into short conversations with other users. No joke.

I finished all the levels and unlocked everything.
IMO, the game is perfect as it is now (even on the NSpire).
The only thing that I recommend to change is the Pause button. "Enter" is much too far away from the playing fingers, so one has a risk of losing while moving his hand to press Enter. "Mode" is more recommended for pausing games; it's quick to press.
EDIT: I made some tests on the PC NSpire emulator, and I noticed that the speed there is normal, unlike on real hardware. I wonder why...
It's because Goplat hasn't made the ARM instructions take their correct amount of time. He's treating them all as one clock cycle.
