You can't mix the Allegro keyboard handler with any other functions, 
because it totally takes over the int9 keyboard interrupt and so the 
BIOS/libc functions will never see any keypresses. So yes, you will have 
to shut down the Allegro handler before using getch(). 

Alternatively, I don't think it would be very hard to #define your old 
code into using the Allegro routines. Whether you need to bother is 
another question: there is no point using the Allegro handler unless you 
need to detect multiple simultaneous keypresses...
