Emu42 for Android is a powerful calculator emulator that brings the functionality of the Windows application Emu42 to the Android platform. Developed by Regis Cosnier, this app allows users to open or save state files, just like the original Windows version. It is important to note that this application does not come with the ROM files, so users will need to download KML scripts and ROM files separately.

With a simple and intuitive interface, Emu42 for Android makes it easy to navigate and use. To get started, users can slide their finger from the left side of the screen to open the menu. From there, they can select the "New..." option and choose a custom KML script folder where they have copied the KML scripts and ROM files. Once a calculator is selected, it will be opened within the app.

It is worth mentioning that Emu42 for Android requires Android 5.0 or higher to run. Additionally, the Help menu displays the original help HTML page from Emu48 and may not accurately reflect the behavior of this Android version. The app also does not include the ROM files or the KML files, so users will need to source them separately.

Please note that the disassembler and debugger features are currently not working in this version of Emu42 for Android.
