I made a patch that adds rumblepak support to Blight's input plugin!
Last sunday I found/created a driver for the rumble function of my controller, but the only Linux game I know that uses it is bzflag. So I decided to add support for it in mupen64 (many games at once
). As I didn't find any documentation on how the plugins should work I decided to peek in the source code of the N-rage plugin to see how it should work and the fftest utility for an example of force feedback in Linux.
This patch is for version 0.0.10 of blight's input plugin as found in the mupen64 0.5 source code.
I added two extra configureable buttons to switch to either mempak or rumble pak, but it seems it doesn't work directly in game unless I make completely custom mempak handling, which is way too much work. So instead after you press the switch button, make a savestate and restart the rom to activate the changes.
The code is licensed under the GPL v2 of course just like the rest of blights input plugin.
