Emu48 for Android

Regis Cosnier

About this app

This project ports the Windows application Emu48 written in C to Android.
It uses the Android NDK. The former Emu48 source code (written by 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:

QUICK START

1. Click on the 3 dots button at the top left (or from the left side, slide your finger to open the menu).
2. Touch the "New..." menu item.
3. Select a default calculator (or "[Select a Custom KML script folder...]" where you have copied the KML scripts and ROM files (Android 11 cannot use the folder Download)).
4. And the calculator should now be opened.

Ratings and reviews

App will not work. It gives me a "permission denied" error every time I try to tell it where the files it asks for are.

After the last update from 15.11.2025 full screen mode is not possible. The navigation bar is always visible in light color on the bottom of the screen even when the toggle switch " Hide the navigation bar" is on. Tested on different devices with different Android version.

(If you're not familiar with HP calculators or RPN, this app is probably not for you). My favourite calc of all time! Im running the 48GX, and it's way better than the original. It's always in my pocket, it hardly ever crashes. If it ever crashes, or if I deleted something, I just load a backup state file. Every time I get myself a new phone, I just copy the the emu48-folder from the old one. Up and running in no time. Setting up from new could be more intuitive, though.

What’s new

- Fix the settings "Hide the status/navigations bar".
