patch for using joysticks in 32 bit applications on 64 bit systems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



unfortunately 32 bit apps don't see the joysticks on a 64 bit system.
this prevents one playing X-Plane (http://www.x-plane.com/) or other
32-bit games with joysticks.

this is a known issue, and already raised several times:

http://www.brettcsmith.org/wiki/wiki.cgi?action=browse&diff=1&id=OzyComputer/Joystick

unfortunately this is still not fixed in the mainline kernel.

it would be nice to have this fixed, so that people can play these games
without having to patch their kernel.

the following patch solves the problem on 2.6.22:
