OpenBOR 4

From humble beginnings in 2004, it has since grown into the most versatile,
easy to use, and powerful engine of its type you will find anywhere. OpenBOR
is optimized for side scrolling beat em’up style games (Double Dragon, Streets
of Rage, Final Fight), but easily accommodates any sort of gameplay style and
feature set you can imagine.

Notes:
* This snap runs better when launched from terminal in ~ (cd ~ && openbor4) however it creates empty folders (Logs, Paks, Saves, Screenshots).
* The games must be copied into: ~/Paks (or ~/snap/openbor4/common/Paks )

Gamepad/joystick: to connect its Snap interface, you might need to type in a terminal:

snap connect little-spy:joystick
