Emu28 for Android

Regis Cosnier

About this app

This project ports the Windows application Emu28 written in C to Android.
It uses the Android NDK. The former Emu28 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 Emu28 source code.
It can open or save the exact same state files (state.e28) 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 on your Android file system.
If you want to modify them, you can download the already embedded KML scripts here: http://regis.cosnier.free.fr/soft/androidEmu28/Emu28-KML-original-134.zip
Or you can download the KML scripts from the original Emu28 Windows application archive (https://hp.giesselink.com/emu28.htm) and add your ROM files.
Be careful about the case sensitivity of the filename in the KML script (Linux/Android is case sensitive, not Windows).

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

Man you never disappoint. I use this on my Z Fold 3 and it's incredibly convenient. I also use your 2 other apps on a daily basis and keep recommending them to others. I tried to make a donation but can't find your PayPal link. If you ever decided to make a paid emulator for the Nspire series, non color and/or color models, I'll be the first one to purchase it no matter how much it'll cost. Your apps have saved my calculators from bricking in more than on occasion, so I owe you!

I used an HP28S in college for my EE classes. I'm amazed at how faithful this 28C emulator is to what I remember. I'd happily pay for this app so that the author continues to maintain it as new Android versions are released, etc. It looks like a lot of work went into it. I don't understand why it's "free."

Like it very much. My old hp-28s has now problems with the keyboard and I am really happy to have one on my mobile.
