Setting up your TI-84 Plus CE
For CalcLite & SuperCalc+ · takes about 15 minutes
This guide walks you through everything you need to get CalcLite or SuperCalc+ running on your TI-84 Plus CE — even if you've never put a program on your calculator before.
The short version: if your calculator runs OS 5.5 or newer (almost all of them do these days), TI blocks the kind of programs CalcLite and SuperCalc+ are. A free, safe, community-made tool called arTIfiCE unblocks it. You install arTIfiCE once, add a few free libraries, copy our files over, and you're done.
What you'll need
- Your TI-84 Plus CE (or TI-84 Plus CE-T / Python edition)
- The charging cable that came with it (it's also a data cable!)
- A computer with TI Connect CE installed (free, Windows & Mac)
- About 15 minutes
Step 1: Check your OS version
- Turn on your calculator.
- Press 2nd then + — this opens the MEMORY menu.
- Choose 1: About.
You'll see a line like OS: 5.8.1.0012. That number decides your path:
| Your OS version | What it means |
|---|---|
| 5.5 or newer (5.5, 5.6, 5.7, 5.8, …) | TI removed support for C/ASM programs. You need arTIfiCE (Step 2) — CalcLite and SuperCalc+ will not launch without it. |
| 5.4 or older | You're lucky! C/ASM programs run natively. Skip to Step 3. |
Don't update your OS. If TI Connect CE offers you an OS update, decline it. Newer OS versions don't add anything you need, and updating can wipe your installed programs.
Step 2: Install arTIfiCE (the jailbreak)
arTIfiCE is a free tool by the calculator community that restores the ability to run C/ASM programs on OS 5.5+. It doesn't harm your calculator, doesn't void anything TI can detect, and is fully removable (any RAM reset removes it).
2a. Download it
Go to yvantt.github.io/arTIfiCE and download arTIfiCE.8xv.
2b. Send it to your calculator
- Plug your calculator into your computer with the USB cable.
- Open TI Connect CE and pick the Calculator Explorer view (the icon that looks like a list of files).
- Drag arTIfiCE.8xv into the window and click Send.
2c. Run the jailbreak
- On the calculator, press apps and open CabriJr (it comes pre-installed on nearly every TI-84 Plus CE; if yours is missing it, you can get it free from TI's website).
- Press any key to get past the title screen.
- Press Y= (that's F1) to open the menu, choose Open…, and select arTIfiCE.
- Wait a few seconds. When the screen returns to normal, the jailbreak is active.
That's it — your calculator can now run C/ASM programs from the normal prgm menu.
⚠️ Important: arTIfiCE un-installs itself on every reset. A RAM clear, a battery pull, a crash, or leaving the battery dead for a while will deactivate arTIfiCE. Your programs are still there — you just need to repeat Step 2c (open CabriJr → Open → arTIfiCE) to re-activate it. The arTIfiCE file stays on your calculator, so you never need the computer again for this.
Step 3: Install the C libraries (clibs)
CalcLite and SuperCalc+ are built with the community CE toolchain and rely on a standard set of shared libraries — think of them as free add-ons that many calculator programs share. You install them once and every program can use them.
Our programs need at least: LibLoad, GRAPHX, FONTLIBC, KEYPADC, and FILEIOC. The easiest thing to do is install the whole set — it's small.
- Download the latest clibs package from tiny.cc/clibs (you'll get a file called
clibs.8xg). - Open TI Connect CE → Calculator Explorer, drag the file in, and Send it. TI Connect CE handles the
.8xggroup file directly.
Using individual files instead: a .8xg is just a bundle ("group") of individual .8xv library files. Some transfer tools — including the Deep Fried Labs desktop app — only accept the individual .8xv files, so the group must be split first. If you need them separated, grab the individual .8xv files where available, or send clibs.8xg once with TI Connect CE and you're covered.
Step 4: Install CalcLite or SuperCalc+
Now the fun part. Send the files for your product with TI Connect CE (same drag-and-drop as before). Every file listed is required — the .8xv files contain most of the program's brains.
CalcLite (free)
| File | What it is |
|---|---|
CALCLITE.8xp | The program you'll run |
CASDATA.8xv | Math engine data |
SuperCalc+ (paid)
| File | What it is |
|---|---|
SUPRCALC.8xp | The program you'll run |
CASDATA.8xv | Math engine data |
CASOVL1.8xv | Advanced integration & series |
CASOVL1B.8xv | Advanced integration & series (part 2) |
CASOVL2.8xv | Solve & matrices |
CASOVL3.8xv | Limits |
CASOVL4.8xv | Taylor series, ODEs & applications |
When TI Connect CE asks where to put files, choose Archive — that keeps them safe from RAM clears.
Run it!
- Press prgm.
- Select CALCLITE (or SUPRCALC) and press enter twice.
If it launches — congratulations, you're done! 🎉 If not, jump to Troubleshooting.
Freeing up memory (if you're low on space)
SuperCalc+ and its data files take roughly 225 KB of archive space (CalcLite only needs about 65 KB). The TI-84 Plus CE has about 3 MB of archive, so most people have plenty — but if yours is full:
- Press 2nd then + → 2: Mem Management/Delete…
- Look through these categories and delete what you don't use:
- Apps — language packs (Français, Español, Deutsch…), Cabri Jr — keep this one, arTIfiCE needs it! — and apps you never open (e.g. Periodic, SciTools, Polynomial Root Finder)
- AppVars — leftovers from old programs or games
- Pic/Image — saved graph pictures
- If you have a Python edition and never use Python, its app is one of the biggest single things you can remove.
Deleting built-in apps is safe — you can re-download any of them free from TI's website later.
If the calculator ever shows "Garbage Collect?", choose Yes. It's normal maintenance, not an error.
Troubleshooting
"ERR:INVALID" the moment I try to run the program
arTIfiCE isn't active. This is by far the most common issue — it happens after any RAM reset or battery pull. Re-run it: apps → CabriJr → any key → Y= → Open… → arTIfiCE. Then try again.
A screen pops up saying a library is missing (or mentions "LibLoad")
The C libraries from Step 3 aren't installed (or an old version is). Re-send clibs.8xg with TI Connect CE — sending it again is always safe and updates everything in place.
"RAM cleared" appeared on my calculator
Don't panic — anything stored in Archive survived. You just need to re-run arTIfiCE (see the first item above). If you sent our files to Archive as recommended in Step 4, they're all still there.
"ERR:MEMORY" or the send fails in TI Connect CE
Your calculator is out of space. See Freeing up memory above.
The program starts but a feature says it's unavailable (SuperCalc+)
One of the CASOVL*.8xv files is missing or didn't transfer. Re-send all seven SuperCalc+ files from Step 4 — they're a matched set from the same release, so don't mix files from different downloads.
TI Connect CE doesn't see my calculator
Try a different USB port or cable (it must be a data cable — some charge-only cables look identical), make sure the calculator is turned on, and on Windows give it ~30 seconds to install drivers the first time.
It worked yesterday but not today
99% of the time: arTIfiCE deactivated overnight (auto power-down after a crash, or a low battery). Re-run it — takes 10 seconds.
FAQ
Is arTIfiCE safe / legal?
Yes. It's a well-known community tool that's been used on hundreds of thousands of calculators. It only changes things in RAM, so a simple reset returns the calculator to 100% stock condition.
Will this get me in trouble on the SAT/ACT?
Exam policies are about what programs do, not how they're installed. As with any program, check your exam's calculator policy — and know that memory resets (or the proctor's "clear memory" procedure) remove arTIfiCE and block these programs from running.
Do I lose anything by not updating my OS?
No. CalcLite and SuperCalc+ are tested on the OS versions already out there, and staying put means your setup keeps working.
