symbios24

try to update the firmware with sudo rpi-update maybe it will fix the error

install the xorg manual to see if its that

or xorg or xserver-xorg-legacy

fofix should be in the ports section in retropie and not in a menu entry it self. plus fofix is not working anymore,try it in an older retropie with jessie...

Try it in Strech but its not going to work there also,There is a list of non working games since jessie im waiting for zerojay to fix them some time...

no worries we will figure it out one day :)

There is a solution for Openxcom i just did not figure out how to add it to the script etc. #288 (comment) when you have time you can add it.

Mouse plays fine on all games that use it.

When i want joystick all i do is play with my snes console. the real thing always perform better than an emulator. no setup no nothing just plug and play

There are packs that include almost everything that you mention-translation/hacks etc,all you need is an everdrive cart to load them, for example the snes games on retropie look really bad...
