 Changelog:
+0.104
+- Fixed graphical problem with xBRZ filter.
+- Fixed mappers 50, 90, 156, 178, UNL-KOF97, UNL-VRC7, MMC3 KT-008 PCB.
+- Fixed possible issue with High DPI monitor.
+- The shortcuts were not applied and saved correctly. Fixed.
+- For the general UxROM mapper use a full 8-bit bank select register.
+- Fixed compilation with QT 5.12 under Windows.
+- Fixed the management of the zapper that now also correctly manages the X coordinates.
+- Updated the Russian translation (thx Alter0ne).
+- Fixed the disappearance of the mouse cursor after two seconds.
+- Fixed the emulator freezing if pressed "Switch Sides" hotkey.
+- Added the rewind function that replaces the timeline.
+  Now it is possible to "rewind" the game. Once the rewind function has
+  been activated (at any time during the game) it is possible to move
+  forward and backward in the gameplay one frame at a time or at different
+  speeds (1x, 2x, 4x, 8x, 16x, 32x or 64x). You will be able to move
+  freely in the recording until you press the "play" button, from that
+  moment all the gameplay memorized after the selected frame will be lost.
+  In the "general settings" you can select the duration in minutes of the
+  recordable gameplay (the different options are: disable, 2mins, 5mins,
+  15mins, 30min, 60mins or unlimited) but keep in mind that the more
+  minutes you can record the more space on the hard disk will be used.
+
 0.103
 - Added support for the UNIF mapper UNIF DREAMTECH01.
