Patching a calculator???????????
« on: November 13, 2010, 07:06:46 am »
Hi!

I've seen on this forum many people talking about patched TIOS. What's this and how do we do this :D?

Thanks to anyone answering rapidly!

Salut!

J'ai vu sur le forum beaucoup de membres parlant de OS patchés sur les calculettes. Qu'est-ce que c'est et comment on le fait :D?

Merci à quiconque pourra me répondre rapidement!

Patching TI's OS means modifying it to fix bugs (both TI-Z80 and TI-68k series - for example, 84+(SE) OS 2.53MP _needs_ an unofficial bugfix to become much more stable), remove protections (mostly TI-68k series), use the OS on other calculator models (see Brandon Wilson's Chameleon), and things like that :)
TI's OS can be patched either with a program that you need to run yourself (sometimes after compiling it), or pre-made binary patches that you need to apply yourself to pristine versions of the OS.

Je suis français aussi, mais sur ce forum, on parle plutôt anglais, même s'il y a une section francophone qu'assez peu de membres, finalement, fréquentent ;)

Well, I'm mostly a TI-68k guy, so I'm not very knowledgeable about TI-Z80 OS patches :)

I've read about a patch which enables running recent 84+ OS on a 83+ (maybe only a 83+SE ?), but like most TI-Z80 patches, I don't know where to get it.

ok, but what could this patch add? i do not see the point of installing a TI-84+ OS on a 83+, though they are quite similar....

There are no important third-party patches for Z80 calculators, if you have some bug, tell us someone could make a patch, but you don't really need one.

Installing an 84+ OS on an 83+ would be kind of pointless, because the 83+ does not have an RTC and so timing functions wouldn't work.

You'd get OpenLib and ExecLib, but I don't think any libraries actually use them.

That is not totally true. As Lionel said, you need patches to run 2.53 MP and have it be stable.

But yeah, if you're not running 2.53 MP you don't really need any patches.

Actually, it is the opposite, it lets you put a 83+ OS on a 84+

oh so that's not for me: I've got a TI-83+.FR (it's a blue one, so I think the 83+SE because my girlfriend has an ungly old one :-X)

[edit]don't think I like French calculators, I deleted the little app which translated the calculator from English to French, much better to program because I understand a bit better English than French (though I'm French  ;D ;D...)

Wow, never even heard of that one :o

Most of the patches are to fix bugs, such as the ones in this thread.

it's normal because, as the product ID says, it is a FR version. As written in my profile I'm French (you know the little guy with a hat and a piece of bread in his hand?) and I didn't find English calculators in my FRench supermarket :/

BrandonW made a patch to run OS 2.53 MP on the 83+SE calcs. ;)

Here's a patch that I use: http://ourl.ca/6542

Rayquaza, are you still looking for a patch?

I think ticalc has a few in only one page, or maybe I'm wrong

Scout David wonders if what he saw is really what he saw =O

So far, I think there is a patch that fixes xLIB problems on OS 2.53MP, a patch that fixes MirageOS problems on 2.54MP (although you need to reinstall it every RAM clear) and a patch that fixes the For() loop glitch mentionned in the glitch thread mentionned above. BrandonW also wanted to make one that allows you to run archived programs, but I don't know what happened to it.

The TI-83+.fr is nothing interesting.
It's just a basic TI-83+, with a blue case and a keyboard with french labels.

2.53MP OS doesn't work on basic TI-83+ because they only have 32Kb RAM, and the OS needs at least 48Kb RAM.
So, 2.53MP can only work on TI-84+/84+SE and on TI-83+SE with the patch.

You can install the patched OS on your basic TI-83+. It will boot correctly, but the calculator is going to crash if you ask it for "1+1", because of the missing RAM page...


The patch was mentionned and linked in that french news:
