I only wonder why BEEP isn't working (Sound: Wave, flag -2 clear and flag -25 set).
My emulators cannot emulate the beepers over the OUT opcode because of speed reasons. The only way is patching the ROM, decode the arguments (frequency & duration) and call a PC internal beeper routine.
In the delivered KML files "REAL71BM.KML" and "REAL71BL.KML" the ROM patch for beeping is disabled.
Remove in the Global section the '#' in the line
# Patch "BEEP.71B"
to
Patch "BEEP.71B"
and beeping should work. The flags -2 and -25 are ignored in the current version, the beeper is always on. The next version of Emu71 will watch the flag -2 (BEEP ON/OFF).
