It's because it's waiting for you to do something. Anyway, move your cursor up to the top left point, then press enter. Move it down to the bottom-right point and press enter. That should work.The first bug?We luv you, TI. :love: :love: :w00t:

I just sent it to WabbitEmu. The first thing I noticed is that they expanded the OS onto page $73 (I knew they were out of space). Which means that the $70-$73 sector is now out of bounds to be screwed with. Which in turn, I believe, means that Ti-Boy would corrupt your OS.that sucks x.x
According to JosJuice, inverted matrix bug was fixed, though.

On a side note, the PDF I linked to on the first post mentions that the OS on the Nspire is OS 2.56MP. Would this mean a release of OS 2.2 is imminent?
According to JosJuice, inverted matrix bug was fixed, though.I didn't say anything about that.

Wait nvm that was Qwerty.55. My bad.According to JosJuice, inverted matrix bug was fixed, though.I didn't say anything about that.
[13:23:09] <Fishbot> They fixed the Matrix inverse bug/
Good news is that there is no downgrade protection. I went from a 2.43 OS to a 2.55 and back. It worked fine.What about WFRNGOS, PongOS and available versions of KOS?
I actually can't afford to waste too much time but I'll try and check this out :DKeep in mind the new PTT adds some more features, though. You might want to check for that too.
See what I can come up with, and maybe it's time to update my PTT patch again, sometime. But not now.
But, a ti8x version of nleash would probably be made a few days later :P
what happens if you press mode and try to look at the clock? does it crash, or just output garbage?
TI should get a new programming teamIt's probably not a team anymore.

In fact, it's very unstable on a basic TI-83+, as the 2.55MP OS is using 48Kb RAM (and the basic TI-83+ only has 32Kb RAM).Nice!
But it works on a TI-83+SE (128Kb RAM).
So you can upgrade your TI-83+SE to a TI-84+SE with the patch (without the clock and the USB obviously).

I don't remember the boot code having a downgrade protection feature. Even if it did, it would have to be certificate-based. A certificate-based restriction could easily be undone by restoring your certificate from an older backup. What? You don't keep backups (http://www.ticalc.org/archives/files/fileinfo/420/42048.html) of your certificate? Shame.Do you mean $3C/$7C-$3D/$7D or $2A/$6A-$2B/$6B? IIRC the former already contains OS code, and with respect to the latter the .8xu format can't have the OS anywhere except the first and last sixteen pages.
Also, the TI-Boy issue can be solved by first copying the extra OS page to the 32 K sector, and then proceeding as normal. For that matter, you could patch the new OS to use that dang 32 K sector instead.
Huh. I thought the sector at 7Ch was unused.Of course not -- 7Ch and 7Dh are privileged pages after all, how else would TI unlock flash in their OS?

Unfortunately, I'm pretty sure they understand ASM. If you look at the SDK documentation, they give a lot of documentation and optimizations that hint at no use of Java.
The problem with TI is, they don't have anyone who FULLY understands ASM. If they hired Calc84maniac, Iambian, Runer112, SirCmpwn, etc., we would get a perfect operating system. And I'm quite sure that these 4--and many more--would love to get paid to create a decent OS for Ti calculators.
Oh well, at least we know it will be a while before Ti-84+ calculators are discontinued
Keep in mind that TI > Us in many areas even still. Take, for example, the USB protocols (or the keyboard for the Nspire), which we don't fully understand.

Take, for example, the USB protocols (or the keyboard for the Nspire), which we don't fully understand.That's just because TI made the USB protocols and the Nspire keyboard. If we would've made those instead, TI wouldn't be able to understand them. They might know a bit more about their calcs than what we do, but we might be better at programming them.

Brandon will probably be glad to know! :PSeems that was a joke. It didn't help that he edited his post putting endless spoiler tags around the part saying it was a joke >_>
Why didn't they tell him directly before?...
except not really :PYeah, so did I. I think I know a way to figure out if it's MP or not in basic. I'll have to experiment a little more, though.
I probably won't bother upgrading to 2.55...I recently went back to 2.43 and I like it... a lot

Just do "1/0" and wait. If your calc corrupts your OS certificate, then you know you're on MP. :PBut if we're on 2.43, the program will quit D:
Still no developer response. But here's that patch I talked about earlier. It does everything from before, and now it puts your ram cleared screen back to normal. (I don't like that big box at the bottom.)
I fixed this in a really cool way. First, I nop'd a jr so that execution falls through to the place where it sets the "ROM cleared"'s coordinates. Then, I changed the page 0 call address so that it just flat out skips the box drawing.
Also, I forgot to mention this earlier, but the OS considers all of the $70 sector to be OS code. I noticed this when I was trying to re-checksum the OS. What this really means is that if you make any permanent changes to $70-72, the OS will be invalid and will "ROM fail" in the self test.
Edit:
The zStart patch is on the way, but I'll be gone for about a week so it might be a while. (Why zStart? You never have to worry about MATHPRINT ever again)
Still no developer response.For the record, if you get some awesome developer response, I'm not gonna hand my thrown over. ;-)
Long term usage of 2.55mp on a real calc:
Don't install it!
I am currently unable to plot any formula's!
When I do so, it splits the screen into 2 parts and turns 'm around :O
(The top of the page is on the middle, and goes down, and when it reaches the bottom of the screen, continues on the top of the screen)If that makes any sense
Anyway, long term usage, don't use it ;)
Did TI's last z80 programmer accidentally microwave their brains or something?Too much crack methinks...
At least Output( actually works, though. *cough*Casio Prizm OS 1.01*cough*

I'm afraid of all the bugs that have been found already!
Man, what a dumb OS...wont even accept apps from a computer...
Goto format graph is supposed to just jump into the 2ND+[FORMAT] menu (it's been there since 2.53MP).how stupid is that? why cant you just press that yourself...
Is it me or does 2.55MP seems to cause plenty of TI-Connect issues to people? You're not the first one to start having problems after upgrading...My biggest problem with it was that it took about a minute for the calc to turn on after transferring the OS... The rest was solved with WFRNG OS :P
how do you make an OS? i want to make a computer on a calculator that does only gaming no calculator lol!Well you have to be very good at asm programming and you have to be able to work well with the hardware. Also you have to write your own system calls. Other than that good luck ;)

After patching and resigning the 2.55MP OS, you can get this on your TI-83+ ! :P

Anyone care to share directions on how to patch this for the 83+SE?I believe this will work (it's 2.53 though): http://brandonw.net/calcstuff/83PlusSE_OS2.53MP.8xu
MathPrint doesn't seem that useful, a new update that removes the functionality of some of your programs just to be able to view fractions isn't worth it!!
Wow, didn't know that...looks coolAfter patching and resigning the 2.55MP OS, you can get this on your TI-83+ ! :P
[big picture goes here]
Critor seems to have it figured out.

Now that Texas will release NSpire CX I hope they have time to make a new NSpire OS with OS 2.55MP for the 84+ Keypad.
Well, 2.55MP isn't a significant feature-wise or bugfix-wise improvement wrt. 2.53MP, which is itself a step backwards for bugs wrt. 2.43.
Now that Texas will release NSpire CX I hope they have time to make a new NSpire OS with OS 2.55MP for the 84+ Keypad.
I'd actually hope not. After 2.1, who knows what they'll put in this time? And as Lionel said, not much of an improvement there :P
