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... /* * Shawn Hargreaves.
