It removes the crash, but it does not make it work unfortunately. I 
tried these examples on Wine, and they worked unmodified which sort of 
raises the question on the usefulness of these Wine tests... I think we 
should post these examples on allegro.cc so that others can test them 
(this adapter is very sketchy).

Now, examining the failure again... the MSDN documentation of 
SendForceFeedbackCommand says that the device must be acquired in an 
exclusive cooperative level. We appear to set the joysticks' cooperative 
level in wjoydxnu.cpp:409 to DISCL_FOREGROUND | DISCL_NONEXCLUSIVE. You 
will note in the log I sent that command fails... perhaps this is 
related? I tried changing it to request the exclusive cooperative mode 
but it still failed. Something to explore further, I suppose.

The adapter acts as two joysticks (you can connect two PSX controllers) 
so that's fine.
