Mouse
DOSBox was originally designed to work with a standard mouse and therefore defaults to relative mouse mode. But using DOSBox on a touch-screen based devices requires additional modes to make input a little easier.
The following mouse modes are supported
•disabled
•relative
•absolute
Relative
Relative mode emulates a classic mouse with relative coordinates. This means that your finger (aka the mouse) lies on one section of the screen, and the cursor is shown elsewhere. Just as on a desktop, your mouse may be several inches from the actual cursor, but will move in concert with it.
Dragging your finger across the screen moves the mouse. It is handy to use the relative mouse mode with gestures like "Long-press", "Double Tap" or
"Two Point Gesture". The Relative mouse mode lacks mouse dragging (mouse down and move). Its necessary use the "Mouse Touch" widget or gestures in order to drag objects while using relative mouse mode.
Every game supports relative mouse.
Absolute
Absolute mouse mode was designed for touch-based screens. Many games support absolute mouse mode and many do not. This is per-game based.
Some games can be fixed with special settings in "Advanced settings->Manual correction". Check the list of supported games on our website.
