Cracks and Patches and Fixes, Oh My!
Posted by Nick on 17 August 2000, 18:06 GMT

Julien Muchembled has released some good ole' back-to-school patches for all you fun-loving folks out there. And, now, in the fourth unsorted list in as many news items, here's what you've been missing for the past three hours!:

  • TIB Receiver for the 89 and the 92 Plus. This happy little number allows the user to load a ROM that TI hasn't signed onto your calculator. As a result, files like Wormhole's OpenOS can now be actually loaded onto your calculator. This offers a world of help in the next application we have for you to gape at:
  • Maxmem v2.10, aka "Your Sole God," for the 89 and the 92 Plus. Maxmem's added support for AMS v2.05 also comes with a bit of a snafu: there's now a computer-based patch utility for the user, because of the relative instability in patching a ROM on-calc. As a result, you now patch your ROM before sending the patched product to the calculator with - guess what - TIB Receiver! It all comes full circle, see? Diabolical!
  • HW2Patch v2.20, aka "Also Your Sole God," for the 89 and the 92 Plus. Patching your calculator with HW2Patch is now the same as with Maxmem: you patch it on your computer and you send it to your calculator with TIB Receiver.

Also, I'm gonna let Thomas Nussbaumer take the mic for a second:

Please archive TI-Chess before starting on AMS v2.04 or greater, otherwise your calculator may crash. For unknown reasons this will fix [a major] problem. Worse yet, not just TI-Chess is caught by that new AMS/TI mystery, but all larger games! I think on the weekend I will release a new version of TI-Chess which just prevents the user from starting the program if it is not archived. As you can see this is not really a bugfix, but a workaround. It's not a TI-Chess native problem.

Haha, Who's your daddy! That's the kind of s**t I like to read!

I assume that patching a file on the PC means that:
1) the patcher decodes the complete OS file to ASM format that one can load in a disassembler.
2) If you can load it in a disassembler then you can edit the code responsible for something like... checking the signature of flash apps?

When is someone gonna release a nicely edited TI-OS and call it AMS 666. haha

Or in the about screen have it show up as "J00 H4V3 B33N R3W7'3DX0R00L0R3D3XR0RN0RD3X0R3Z B4H J00L13N M00CH3MBL3DX0R0L#!(#&*!#&"

Or something.

Haha!
the patcher debugs the tios in VTI (he didn't disassemble it)
The code that checks for the signature is not in the file that you send to the calc, but is on the calc, in the first block of the flash rom. it is impossible to write in that block without some hardware manipulations (like desoldering a pin of the rom chip)

No, I think all it means is it does exactly what it did on the calculator, but there's less chance of a freak error than on a calculator. <What I think> The author used VTI to find out what the problem is, and wrote up code to change it. He then assembled the code, and wrote a program to insert this code directly into the .tib/.89u file, without having to do any complicated deassembling/assembling. </What I think>

cool, now we can mess with ti's rom files and be able to use them. a while ago i tried to use a hex editor to mess with a tib file--to write my name in the menus at the top of the screen or in the about screen--but i couldnt send the rom because of the rsa thing. looks like its now possible. if this works itll be better than carving your name in the back of your calculator--you can have your name embedded in the rom.

I did the same thing, and ended up needing to replace my calc.

MY sole god is Nike (no mythological pun intended). I find happiness in programming, not in leaching programs from those far greater at programming than me.

Slightly off-topic question: is there such a thing as Zen programming?

There is one problem with the TIB Receiver, though. As distributed, TIB Receiver does not support AMS 2.05, so those of you with AMS 2.05 will just have to wait for the next version to be released before you can use MaxMem or HW2Patch.

Strange. Now I need 2.04 to have full access on 2.05??? Argh!!!

Check the news boards from earlier this year. There was a thread or several about wormhole's departure from the TI community and about him releasing his work. I don't remember when it was, but I think it was shortly before our most recent (and most commented) fake news item.

I believe that openos is the French ROM that is under development.

The only one that has been released did absolutely nothing, but was just intended to demonstrate how to create .tib files that were in the proper (unsigned) format.

NO!
1) there is no French rom under development: it's an international rom
2) openos is an other rom that wormhole started to develop. He released the sources when he left the community.

No: OpenOS is Wormhole's (unfinished) ROM; the International one (not French) is called LiteOS. For more information, go to the URL. (At the moment, it's just a message board, but it may change as devolopment continues)

I don't think you want the current version of OpenOS. As I understand it, it does nothing at all yet. Stick with TI-OS until a real replacement is released (you'll probably be waiting a long time).

I have just finished the uploading of the "fixed" TI-Chess version 3.01. Additionally the distributions contains now a FAQ (frequently asked questions) with all kinds of answers, links to tutorials and other related resources on the internet. And there are tips within how to thanks the authors ;-).
I don't know how long it will take until the new version is available on ticalc.org (I have uploaded other files on monday and they are still not available), but if you want to get it just now, you can download it from the TI-Chess Team HQ at http://go.to/tict or http://go.to/tichess
