I know about the stuff on TI Calc. That's where I get all my calculator stuff. 9 out of 10 of them usually work. Sometimes they need a patch, like Mirage does.

Do you know if I can use the key signing to work on my NSpire so I can make it have a real 84 OS instead of the emulation?

Nope, because the Nspire is not even a z80 processor. It's an ARM processor, which is why the TI-84+ has to be emulated. Even when people will write third party OSes for the 84+, first, people would need to crack the TI-Nspire to allow custom OSes to be installed instead of the TI-Nspire one, which would completly remove the TI-84+ emulation, which isn't even a real 84+ OS.

for all these various reasons, I won't get Nspire until either it's signing key is cracked or unlocks its asm, or TI makes them more programmable...

UNfortunately the signing key is 1024bit, so most likely it will never be cracked. Look how long it took flopusmaximus to factor a 512bit number

, and doubling the bits it not doubleing the time. Anyway, hopefully they figure out how to do asm support, because i don't see TI unlocking their new baby just for us

Yeah, I am really curious why ASM wouldn't be possible to add to both the TI-Nspire series and older Casio calcs. In 1994, Dan Eble/Magnus Hangander figured out to implement ASM support on the TI-85 by just sending a modified .85b file to their calc. However, then comes the whole thing about having to learn how to program on that new processor, since it's not z80.

I hear the ARM processor works very well with C, unlike the z80 processor.

I wish they would listen to their customers like Casio did with the ClassPad 300 (their touchscreen calc) and make a C compiler

So, if the signing key WAS cracked, it would be possible to load a real 84 OS on my NSpire? It would be really awesome because the NSpire has more resources. It's really slow when you use the 84 emulation, but that's probably /because/ it is an emulation. If there were a real OS that would work, then it would be way better than an 84. ...Or would it throttle all the programs to make them super fast? ^^

DJ Omnimaga · « **Reply #533 on:** October 14, 2009, 07:46:28 pm »

Nope, for such thing to happen, the TI Nspire OS, after cracking, would need to be modified in order to delete the current OS, if it's even in z80, to replace it with another. I still think this would be impossible because the emulated 84 OS of the Nspire is not even written in the same language as the real 84 one.

calc84maniac · « **Reply #534 on:** October 14, 2009, 09:21:37 pm »

We should probably make a more accurate (and faster!) 84+ emulator after we crack the TI-Nspire. The current one adds special opcodes to interact with USB and the Flash memory and doesn't include some of the instructions from the real z80 (but TI never used those in their OS in the first place).

DJ Omnimaga · « **Reply #535 on:** October 14, 2009, 09:26:15 pm »

If a faster emu is done, I would like if a original speed mode was included, though, so people can still play 84+ games at their normal speed

calc84maniac · « **Reply #536 on:** October 14, 2009, 09:49:15 pm »

Well I don't know if it would be much faster than a real TI-84+, but I know that the current one is slower.

DJ Omnimaga · « **Reply #537 on:** October 14, 2009, 10:05:44 pm »

I didn't notice much of a difference in BASIC games, though (I only tried Reuben Quest 2 and Illusiat 13, though).

Builderboy · « **Reply #538 on:** October 15, 2009, 12:29:55 am »

Basic games don't seem to have much of a difference, but assembly games do. I tried Bubble Bobble (it worked!!) and on the highest speed setting, it was more than twice as slow

brianbdm · « **Reply #539 on:** October 15, 2009, 11:17:51 am »

Haha. I tried that game, too. I thought that it would be to my advantage that it was so slow, but, man, I still only could beat 20 levels or so. I think that there were 60.
--------
So, at this point, our best option is to crack the signing key, and instead of making a new OS, we'd fill in for TI to make a better emulation. That way it'll still work with the new processor.
