Ti85 emulator. You will need a rom file, it is not included.

After starting the application you need to switch the calculator on with the ON button. There is also a auto time off. After some time when there is no input it looks like that the calculator is stuck but it is sleeping wake it up by press the on button.

With the save/load buttons you can save the calculator status and load it. The reset button will reset the calculator and settings.


Rom file location:

In most countries, it is illegal to share or download ROM images for devices you do not own. Dump your rom, rename and copy to:


Load vti save file:

Rename and copy the vti save file to /home/nemo/.ti85emu/ti85emu.sna and then push the load button.

Sending program files to the emu:

You can send *.ti85p files to the calculator, it works only with single program file.

  • Rename *.ti85p to dummy.send and copy to /home/nemo/.ti85emu/
  • In the calculator push 2nd -> LINK -> F2 (RECV) then push the send button above the display.
  • The transmission of the file should be quick. Now you can push the on button to end the transmission.

Error 35 will pop up but the program should be there.

There's something wrong with the layout on Aqua Fish with SFOS The button labels aren't showing and it makes the calculator very hard to use. They do work and response to pressing. Here's how it looks like.

Thanks for reporting. I will have a look into it. But I guess I need to wait for a new sdk.

Latest SDK Release version 1701-1 ( (Iijoki) )

Latest early access SDK version 1707 ( (Jämsänjoki) )

Have you thought about creating a layout with silica components and maybe also create support for landscape mode? Especially the second one would be wanted.

halftux's picture

I am sorry to say but sailfish doesn't offer silica components for qt widgets. Same is with landscape orientation it is not included. There is a trick to rotate the app but would be really much work and don't know how the elements should be placed that you have a nice landscape version.
One thing I could do is to load a custom style sheet file. So for the moment I planned some settings windows and maybe a file browser for loading save files or rom files. We will see what the future brings.

Sorry my bad... Downloaded the Ti rom v10 just renamed it to ti85.rom and placed it under /home/nemo/.ti85emu and without the dummy.send renaming part works great. Thanks for providing this awesome app on Sailfish. I down on my former N9, some more to go

halftux's picture

No problem. The dummy.send is only for basic programs that you could write on your own and send to ti85. However this is a experimental feature. The next release will have support for loading vti save files. So you can save your status and all programs with vti and then load it with ti85emu. This is a more promising way to transfer basic programs to the emulator.

Have a look at ticalc.org many programs already there.

sound interesting enough and my anticipation levels are high. Keep up the good work man

At first sight, I also believed it was not working, until I pressed the «ON» button...

halftux's picture

Ah thanks I forgot to mention, first you need to switch it on yes. There is also an auto power off. When there is no input after some time, the calculator switches off and you need to press on for wake him up again.

I will work on the description a little bit more.

Been waiting a long time for this, but sad to report, have gotten some roms, renamed as you instructed, renamed as the app advised, nothing seems to get it working

halftux's picture

So does the app hang too? I tried the rom from ati85 the application hangs running in emulator.

Then I used TI-85 v10.0 from nitroroms and it is running fine. Do you have a Jolla or another SF device? Which firmware does the phone run?

DameCENO's picture

As I already pointed out above, I was the one doing some renaming errors, working great.

I can't get it to work. I copied the ti85.rom file from ati85 (the N9 TI emulator) and now Ti85emu won't even start.

halftux's picture

The rom file from ati85 seems not to be a real dumb of the rom (only 89kB). Try to google "ti85 rom files" the rom file you should use has a size from 128kB. Please report if this is working for you.

I am not owning a Jolla so I can't try.

Thanks for the feedback.
