 DESCRIPTION
 
+WARNING: WITH VERSION 1.3, THE STATUS FILE HAS BEEN MODIFIED AND IS NOW FULLY COMPATIBLE WITH THE WINDOWS VERSION AS IT SHOULD HAVE BEEN.
+HOWEVER, BEFORE THE UPDATE, BACK UP YOUR DATA BECAUSE YOU COULD LOSE THEM.
+
 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.

+  * in the menu:
+   - touch "New..." to create a new device
+   - or touch "Change KML Script..." to change the current KML script and ROM location
+  * select "[Custom KML script...]"
+  * select the FOLDER
+  * pick the calculator (which should be "Eric's Real 50g (Large Cropped)")!
+  And because, the file "FOLDER/rom.49g" is not readonly anymore, you can save your port 2.
