Fuse core for WII U crashes after selecting joystick, and no on-screen keyboard.
As I write in title, after selecting joystick from Controls menu for Port 1 (Kempston, Cursor or so) and returning to game, Retroarch completely freezes, and WII U must be hard shut down to restart.
Also, on-screen keyboard over the defined key (- in menu, but also any other defined) does not work. It shows nothing.
It's the same for both stable and latest night-builds.

Just trying to consolidate the issues these are all the same issue https://github.com/libretro/fuse-libretro/issues/121 https://github.com/libretro/fuse-libretro/issues/124
Hi. Just to add a clue to the cause of this issue which may assist.
I am aware that this was a problem which started after a certain update; since I used to be able to use WiiU/RetroArch/Fuse core with no issues.
I've just gone back to discover exactly when this was; by restoring old Fuse cores. I've found that the break occurred after v1.9.14, e.g. that works fine and then if you use >= v1.10.0 then this crash will occur when trying to make any config change around input.
Hopefully this will be of use in going back to compare the differences in WiiU/Fuse after v1.9.14.
Regards,
Simon.
