Oh yes I've messed up calcs...There was this one idiot at school who refused to stop bugging me for games, and kept forgetting how to run them. A quick connect of my calc to his and then a session of my LINKFUN program fixed that (see URL). Nothing feels better than wiping someone's archive.

I did something similar, without knowing it. This kid at school had an 86 and the first thing he would ask me was if I had games for his calc. He wouldn't leave me alone so I took it home and loaded it up with games. I put on this Final Fantasy game from the ASM section that turned out to freeze the calc making it necessary to take out all the batteries wiping the mem. He hasn't talked to me since. I voted the first one, by the way.

Heh ... Will and I made that game. (Actually, he did the programming and put me as an author)

Well then, thank you and/or Will for making such a program to get the kid off my tail.

fortunately for me (or is it unfortunate) nobody at my school has an 86 but me, and none of the 83+ users trust me enough to let me take theirs home.

It didn't work (the URL, not the program...)

It appears ticalc.org limited the URL length...

That doesn't appear to be the problem, as I've seen longer URL's than yours. Just post it again, if you don't mind.

Trying again...

Works

didn't work this time either (for me)

please!
I do NOT want to know about your *cough* URL *cough* experiences...

I know how you feel when people always ask for games. What you do is give them something cheap, like a program that says "This is a game." then quits. Or, make a bunch of empty programs and name them things like "MARIO" or "TETRIS". That's fun.

or, just:

:AsmPrgm
:3E70
:D388
:C9

w00t!
(It crashes!)

That is

ld a,$70
out ($88),a
ret

So I guess writing 70h to port 88h causes the calc to crash?

I tried with calcsys and it didn't crash (or am I just stupid?)

Maybe I got the 70h and the 88h the wrong way round- look in the 'Cool' text file. (If you look at my website ('web page' link) there is a program called 'Advanced Controls' that allows you to do funky things with your TI-83 Plus (output values to port, turn on fast circles, lowercase etc). One of the features is 'Reset RAM'. That uses the thing I said above.

Oh, I do not usually program in HEX- I normally use ASM and TASM with Devpac83. All I know in HEX are 3Exx (ld a,xx), D3xx (out xx,a) and C9 (ret). Try this:

:AsmPrgm
:3E60
:D310
:C9

(Or:
ld a,60h
out 10,a
ret
)

That shifts the screen up half-way. (Not permanent- turn off calc to reset).

ld a,77h
out (04h),a
That's what you put, I think...

Sorry, not
out (10),a
but
out (10h),a

oh geez this is scary

You can put just about anything, just leave C9 out and it crashes...

That's why I made that link disabling program a long time ago... I wish I still had it... :(

While *your* doing that, make the fake MARIO or whatever compatible with MirageOS and lock it from the edit menu. That way it looks like it is ASM!

Afterwards, go give it to someone at school and sit in a chair with your feet on the desk until the person who got it gets mad. It's highly entertaining. After he gets mad, just say w00t! and he will shut up. It worked with one of my friends.

or, make it on your computer and click the little box in the corner!

oh wait, then you could still tell if it was an asm prog or not from the regular prgmNAME menu.

For TI-83+ users:
You could make a blank ION game and put in after the ION header some 83 stype ROM calls:

call _clrlcdfull

or similar. (If you do not use the bcall(_) system, the calc will crash).
Compile them with names like 'Mario' or similar and send to their calc...

Or send the 83+ version of ION to a friend with an 83 calc- it won't work at all. (They tend to get annoyed. Shrug and say, 'well, your calc is too old and won't support ION. Too bad.')

Ofcourse, cause it thinks you're tryin' to call that location. what's always fun is:

neverleaveloop:
bcall(_clrLCDFull)
bcall(_homeup)
ld hl,almostthere
bcall(_puts)
wait:
bcall(_getcsc)
cp 0
jr z,wait
jr neverleaveloop
almostthere:
.db "You're almost "
.db "there, a little"
.db "farther...",0

The link doesn't work
