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.

Since 0.0.9-10 the emulator has a settings file so you could have your rom file where you like, the file must have a ".rom" extension. Start ti85emu click the menu button, click on settings and then select file, select your rom file and click open. Finally you need to click on ok and close afterwards the application and restart.

Also the load function (*.sna;*.sav) and send function (*.85p) has now a file dialog.

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 (not needed anymore) you can select your rom from any location:


Load vti save file:

Rename and copy the vti save file to /home/nemo/.ti85emu/ti85emu.sna and then push the load button. You can load the file from different locations through the menu.

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.

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.
