• Bug fix in the low battery watchdog
• RTrigger/LTrigger keys can be used in the keyboard settings menu to navigate between Normal, LTrigger and RTrigger compose mapping.
• New “Command” feature in the emulator menu:
  • You have now to choose the command you want to run using arrows.
• Default Hotkeys can now be set in the keyboard mapping menu (useful to add hotkeys on existing/previous keyboard files)
• Remove dead code (such as printer, breakpoint, trace support etc…)
• Bug fix such as: while saving state using hotkey in ultra-mode, thumb image wasn’t properly saved
