| last change | Android WIP: * Rename gui_jni.c to gui_android.c - now quite android specific. * Implement generic EGL driver with very minimal Java wrapper * Run emulation in separate thread, and implement simple queue for inter-thread communication. * Add menu/action-bar items for start + reset |
