- Floppy LED (visible only with virtual keyboard) - Virtual keyboard: - adjustable: position, size, transparency - persistent: saves position, size, transparency automatically (separately for portrait and landscape on Android and iOS) - visual und acoustic (switchable) feedback - Virtual joystick in two different sizes - Virtual mouse (selectable instead of joystick): AMX, Reisware/Gerdes or Symbiface II (PS/2) - Original sounds of disk drive, cassette relay and keyboard (can be switched on and off) - Zoom function (display without border), alternating with and without full screen; persistent (separately for portrait and landscape on Android and iOS) - Audio emulation deeply revised; output quality significantly improved (you can select from 4 output frequencies) - Vortex memory extension SP64...SP512 - Jarek memory extension 576KB...4096KB - Bank-switching speed dramatically improved; correct emulation of C3 mode - IPv6-enabled web server similar to M4 board (upload and download into/from the emulator via web interface) - Autostart behaviour improved (automatic file selection and deactivation) - Minimal audio latency on Android (Oboe) - User interface improved on Android/iOS - Setup settings are saved immediately - First preparations for new user interface - Adjusted to SDL version 2.0.22 (which needs to be installed manually on Linux) - Fixed bugs: background-foreground-changing behaviour on Android, real-time speed, video output speed (in particular on Android, iOS and MacOS, I think also on the Raspberry Pi), memory leaks, M4 sockets, file access on Android and iOS
