This is no way changes the possibly of cheating. That will not change unless the flash unlock exploits themselves are fixed.

The guys over at T3 don't get that. They think everything we do makes students cheat :P

Congratulations to thepenguin77... and congratulations to TI as well :)
When they make a nasty move, the community notices, looks deeper... and finds/does some pretty interested things that wouldn't have been found/done so soon without TI's move. And we all laugh at TI's renewed fail.

Yay!  This is wonderful!  Thank you, thepenguin77!



Does anyone see the irony here?  We are an anti-troll community and we spend all of our time trolling TI.  Go figure.  :P

hmm, what's supposed to be the max upper limit where that program can execute? FFFF? i just ran it on an old, extra pages 84+ BE and it crashed at FFC7.
anyways, is this the last big step to be taken? the 83/4 series has always been moving forward to some larger goal after achieving one that was previously thought impossible (grayscale, sound, custom OS's, internet access, and now this). is there anything else that remains to be done, now?

From the title it seems like this was the last step to us being able to completely control the calc

Sure they can. They can just revise the hardware. A little expensive, perhaps, but doable. Then all future students will be stuck with the changes.
Do you really think they'd mod the hardware to lock us out? That would suck and be pretty expensive for TI
If they did, how long do you think it would last, looking at recent history? :P

Either way, great job ;D

There's still Bluetooth and WiFi left, as well as the ability to put the calc in MSD mode... But as far as control goes, we've achieved everything. (Or have we? Is the 83+ boot code unwritable?)

well for the 84's we've achieved everything. The 83 might be impossible from what I read

It's because the stack corrupted stuff, causing a crash. It's unrelated to the actual execution protection.

I'd like mode 0 interrupts/extra i/o ports on the 1999 83+'s.
Also, we could do more reverse engineering on the ASIC.

One great feat at a time, though.  ;)

Please correct me if I'm wrong, but in order to have mode 0 interrupts, we'd have to redesign the Ti-83+ HARDWARE.  No software in the world could make use of mode 0 on the current Ti-83+s.
