Emu48 for Android3.0



Publisher Description

Emu48 for Android -

Emu48 can emulate a HP38G, HP39G, HP40G, HP48SX, HP48GX, HP49G and more.

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:
https://github.com/dgis/emu48android

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.
