Emu48 for Android
Fork me on GitHub

This project ports the Windows application Emu48 written in C to Android.
It uses the Android NDK. The former Emu48 source code (written by Sébastien Carlier and Christoph Giesselink) remains untouched because of a thin win32 emulation layer above Linux/NDK!
This win32 layer will allow to easily update from the original Emu48 source code.
It can open or save the exact same state files (state.e48/e49) than the original Windows application!

Some KML files with theirs faceplates are embedded in the application but it is still possible to open a KML file and its dependencies by selecting a folder.

The application does not request any permission (because it opens the files or the KML folders using the content:// scheme).

The application is distributed with the same license under GPL and you can find the source code here:


1. From the left side, slide your finger to open the menu.
2. Touch the "New..." menu item.
3. Select a predefined faceplate (or select a custom KML script folder).
4. And the calculator should now be opened.


Android version 4.4 or later.

It would be nice if there was the "Hide the status bar" option on settings to increase the calculator. Many thanks for this free app.

Great application!!! It's better than Droid48 and we can simulate other models. I'm missing "Hide the status bar" too. But...it's perfect, like PC.

Great!, thank you for the app. Can you tell me how to load objects (i.e. programs downloaded from hpcalc.org) once I have choose a Kml. Many thanks.

I really like it! I use it daily. Many thanks. Can I make a small request? When starting it shows the KML compilation result. I have to click on ok (and click on new). Is it possible to start a default one calculator without clicking on the ok button?

Really great. The only thing that would make it even better is a true full screen mode which hides both the status bar and soft keys.

Excellent, Really happy with this! I can key in a program and it takes it. I just need to figure out how to transfer my programs to my other Android device and my chromebook and of course to Windows. I will probably have to get a Windows tablet now as well. Thanks Regis!

Thank you so much. I have used an HP48gx for many years to do so many things. To have a true emulation on android is a dream I have had for a while. I use my 48 as the control panel for my homebreq CNC machine using the RS232 interface. Is there any chance of making the I/O work! (Still dreamibg)
