I already have the disassembly, think. I don't understand it all that much. I was given a .7z and it gave me an .rtf file. It's got hex on the left and a bunch of characters on the right.

Oh, then can you check if it's got any other configurations? or anything? A full readout of the descriptors and such. If it's only the mass storage class, and nothing else, then that's fine.

I love being quoted. ;-)
I don't know, ever since getting an Android phone and seeing how it's run on many different physical phones, I've been interested in seeing OSes be very portable.

Yeah, this has been a good year for programming both the NSpire and the TI-83/84. I do hope this continues next year. ;-)

Yeah, I'm not writing that for you at all. That's kinda a pain to do in some ways. But, nemo gave you good links (to javadoc, I would still search for some tutorials).

Now correct me if i'm wrong but if we swap two bytes, the checksum should be the same and the program should run right? However it would fail if one of the bytes was the checksum right? Maybe this could be used to find out where the checksum is if we don't know it already?
Yes if we swap two bytes programs still run. Also at address 0x0020 there is a checksum of the program, but it excludes a few bytes which I have not found yet. There is also a checksum of just the first 32 bytes of the header, but i hav not found that either. So far though most of the header is cracked. Currently I'm writing documentation file for the entire app header which is $7000 bytes long. If we're lucky we could get a test NOP app running before the year ends.
That's awesome, really. I wish I had a prizm, because I would write the program to test the checksum for you, and have it automatically try and resent it. It shouldn't be too hard. I'm eager to try and break the usb protocol. If anyone wants to give me a data logging for usb, and the file that they sent/received, I would be very happy, and would try and analyze it. (Simple USB Logger file is a free logger, or of you can log the bytes to a text file, that would be fine, too.)

I know. I just can't figure out how to make it so that EVERYTHING generates a KeyEvent, disabled or not. I just had an idea though...
EDIT: By the way Graph, I was at Mall of America today, and I saw your avatar on a sign
My avatar? You mean the qr code (which might change soon)?

Wb. I don't know how hard it is to be admin of omnimaga, but i'm sure it's not easy.
Fixed. It is difficult typing on an ipod sometimes.

Oh, okay, I see it now. Well, let's attempt to get all the files, then. ;-) Does casio have a main site like education.ti.com?

And do we have those bytes for all the files? Excluding .bmp, .txt, and .csv of course. And why is hello world listed at the top?

It's probably that you can't see the cracks, but I'm pretty sure there are cracks in the lCD.

38. Steal their computer.
Especially don't do this to a hacker. ;-)
(If you've seen a hackaday article about this recently, you know what I'm talking about)

That is actually an amazing increase in speed. Very nice!
