alright thanks for the help!!

There is a really nice one called Tetrica. I can't remember where I found it though. It has multiple game modes (classic, sadistic, touchdown, etc.)

Oh, and don't forget to create a group on your calculator with all your games on it there so if the ram is cleared you can still have your stuff. It makes recovery a lot easier than having to re-download everything.

So my friend figured out you can download games on to a calculator and I was just wondering if anyone knew of a good Tetris that I could download for TI84+ and TI84+ CE. I would really appreciate it if you could find me one that works well.

It probably is not even a big deal if you take it out, TI certainly has made it quite simple to do (as opposed to disassembling the rest of the calc), but you shouldn't do this unless literally no solution will fix your calc and your last resort is to replace the battery.

What they said ^

I just didn't see that it was a CE

This is just something I saw that seems weird to me, but this:

Input "",Z
DelVar Z

can be much simplified into this:

Also, I don't know if it would help with your issue, but does it work if you store the variables one at a time in the list? Maybe for some reason storing two breaks it? (I'm don't have my calculator right now so I can't test it.)

Don't take it out, it's connected to the calculator a certain way. Possibly yes, so don't do it

That's why TI added the reset button
It works the exact same way as if you were to take out a battery on the 84+


The only way to raise the error you claim to be seeing is by writing


where [A] - [D] are the matrix names (not just the letters surrounded by brackets) given under [2ND][Xֿ¹][NAMES]. The real variables A - D always stored just regular values, so


works just fine.

The solution to a complex problem is often a simple answer.

Input "(",A
Input "("+toString(A)+", ",B
Disp "("+toString(A)+", "+toString(B)+")"
Input "(",C
Disp "("+toString(A)+", "+toString(B)+")"
Input "("+toString(C)+", ",D
Disp "("+toString(A)+", "+toString(B)+")"
Disp "("+toString(C)+", "+toString(D)+")"
If A=C
Input "",Z
DelVar Z
Disp "Y="+Y₁

So basically, I have assigned an input into A, B, C, and D. I put 1 into A and B, and 2 into C and D, and on the lines


It gives me a data type error (storing matrix to list) on the variables. After trying different ideas for 30 minutes with the people on my discord server, including:

  • Close curly bracket (no change)
  • Using expr() incase they were strings (data type there, so it is a value)
  • A[1] instead of A (syntax error on the brackets)
  • [A](1,1) (same thing)
  • A(1,1→A (again, syntax)

We're out of ideas so I'm turning here for help. Any ideas?

alright, thanks it worked

I only see a huge battery, will it break if I try to take it out?

Re: Frozen Ti-84 plus CE by jackjackatackjackjackatack, 16 Sep 2019 20:57

Mechanical pencils are very useful for reset buttons… just click it out a bit and hit the button.

Possibly. Sometimes bots can bypass reCAPTCHAs, so I guess they changed it for security reasons


Try pressing the small "reset" button on the back of the CE (take the case off) with a paperclip or something


Try taking out all the batteries, pressing the on button for about 10 seconds, and then putting the battery back in.

Re: Frozen Ti-84 plus CE by TrenlyTrenly, 16 Sep 2019 13:05

So, I just bought this today and didn't do much besides download a couple games onto the calculator when I deleted a game file it froze my calculator. Anyone know a way to reset it because it wont detect on the program and I can't press anything.

Frozen Ti-84 plus CE by jackjackatackjackjackatack, 15 Sep 2019 23:17

That is quite strange. Maybe they had some kind of problem with spam requests to their site for downloading?

Re: What's TI doing? by UBERhelp1UBERhelp1, 13 Sep 2019 20:14

I'm trying to restore my friends SE to it's original state, so I can install the default flash apps and such to his calculator, and TI added a form when downloading any OS. Before, it used to be where you just check the reCAPTCHA box and download it, and now you need to provide certain information….
