Full description
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: https://github.com/dgis/emu28android 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. LICENSES Android version by Régis COSNIER. This program is based on Emu28 for Windows version, copyrighted by Christoph Gießelink & Sébastien Carlier.
