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.

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

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

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?

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.

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.
