Z button binding issue on QWERTZ keyboard layout

[jancborchardt]

All the emulators use Z and X for A and B. On a US layout this is no problem but on a QWERTZ layout (e.g. in Germany) where Y and Z are switched, you need to stretch your hand a lot and the left/right is also reversed.

What would be nice if whichever button is bound to Z for a specific emulator would also be bound to Y, this would take care of the problem very flexibly.
