DESCRIPTION

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


NOTES

- When using a custom KML script by selecting a folder, you must take care of the case sensitivity of its dependencies.

- Disassembler
- Debugger
- Macro
