ah okay, any good hacker can get those keys, or with the right connections, not saying they arent good hacker or anything.

it failed
there is no message of install completed.

and gameboy emu cant be started,

again fail

What do you mean with "fail"?

Failure it isn't able to run the gbc emulation.
It crashes with vertical stripes after a little time.

Atm I am not home but keeps suggestions for fixing coming

Which games are you using?

Also, "good hackers" has nothing to do with it.  The greatest hackers of all time could combine their knowledge locked together in a rkoom for two weeks and still not get those keys.  It would take years to accomplish with the best resources available and an unlimited budget.

I am not using any games the  hacking didn't work.

Btw did I say theright connections.it isn't that hard to get the key if you have somebody that can leak them.


Butanybody got suggestions to fix this. 
I get vertical stripes and then it automatically reboots

Btw did I say theright connections.it isn't that hard to get the key if you have somebody that can leak them.

TI most certainly guards them very closely, its not like we can go up to them and ask them for the keys, even if one of us has connections there, which I know a few of us have.

so where can i download super mario/tetris?
preferably ti nspire optimized, which as small as possible file size

We don't discuss downloading copyrighted ROMs here.

After installing ndless, you just open gbc4nspire.tns.
You can only use roms for the original Gameboy, or Gameboy Color, GBA's are a whole different system and not supported. On your computer, you have to rename the rom so the file extension is .gb.tns or .gbc.tns, then you can use the computer link software to send it to the calculator.

There's nothing we can do about that, because the LCD TI put in has a horrible response time, causing the blur. It reminds me of those screens in laptops from the 90's, where you had cursor trails even if they were disabled .
