TI-83+/84+ OS glitches compilation thread (all OSes)

[ralphdspam]

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.

[DrDnar]

The Mathprint OSes have a lot of glitches that are not reproducible on anything other than your own unit.

[Freyaday]

Yeah. It doesn't happen in Wabbit over here, either. That said, could someone else try it on a real calc please? I don't have another one to try it on.

[ralphdspam]

Have you tried resending the OS?  That might help.

[Freyaday]

It's not really a problem. I've also sometimes seen the text char 228 have the bottom row filled, which is abnormal.

okay, I just remembered that I ran into a bug the otherday and I am not sure if it has been posted yet. I would go back and check, but I have limited internet time on a slugish connection (public library+middle of elsewhere). Anyway, I have a screenshot of it on my computer, but not here, so I will try to remember how I managed it. I think I did something like this in the screenshot:

Code: [Select]

:{1,2,3,4,5,6,7
:Disp Ans/3
:Pause sum(Ans
I think that is what I did. Anyway, what happens is that the when it is paused, you can start to scroll the number left/right as if it is a list or string that is too big to fit on one line. The key, I think, is that the value after Disp needs to be too long to fit on one line.

Confirmed for 2.53MP.

Normally, I'd come in here and say, "Well obviously the OS isn't setting ... flag." But this time, we are dealing with some really nasty stuff. I'm sure the problem is that a flag is incorrectly set, but the question is, which one? Stuff like this starts to fall into the category of editBuffers, and those are full of so many undocumented things that working with them is almost impossible.

This problem probably isn't worth fixing, but I'll probably still try to figure it out for educational reasons.

We finally figure out the fraction glitch. What happens is a side effect in the universal flash unlock ends up modifying the OS. So what I've done is make a mod to the OS so that even when the flash unlock tries to change it, it will end up having no effect.

In short, run this on OS 2.55 and you won't have to worry about the fraction glitch any more.


Edit:
   Also, by the way this works, it can't happen in 2.53. However, it does occur in 2.43, though I have no idea what the side effect is.

Weregoose found another one here.

On 2.55MP, if you take a fraction and multiply by another fraction, the home screen glitches and starts writing from the middle instead of the top of the screen. Only way I know how to fix is ram reset

Found this today.
TI-84+SE
2.55MP
Had it in Classic, but I don't think it matters.

Put calc in Frac
Goto the Window menu and change at least one of the options so that it has a thick / in it
Change mode to something other than Frac
Open up the Window menu again
Either scroll down to the option with the thick / in it and then press Y=, or scroll one past.
The z address is now 31 instead of 0 (I counted)
The z address can be reset by turning the calc off then on, but so long as the thick / is present in a Window menu option, it can be retriggered by the above scrolling process.
If the calc APDs while the z address is 31, it wipes the graphscreen without marking it dirty, leaving a blank graphscreen that can be restored with a ClearDraw.
The way to fix this is to remove the thick / from the Window options, or put the calc in Frac mode, and turn it off then back on.

Lol, the answer to the problem is two posts above yours. But, you're on your way to finding more glitches

As a side note, we're trying to get people to use our new universal flash unlock that does not corrupt the OS. This will make this problem less prevalent, but with the large number of deceased programs, my OS patch might be the only cure.

I don't see the glitch on WabbitEmu.

You need that patched bro.

You can turn your calc off then on again. that fixes it

Does anyone have an animated GIF of this glitch?
