Just went through the search for FH ROM 9.05H. Finally found it and here is a link to download: https://www.dropbox.com/sh/jd85os8e9qmtsrc/AAAliLyJmTdDpMOdGLJmPfkba?dl=0
fh_u14.sl2 Sound U14 L2
fh_u15.sl2 Sound U15 L2
fh_u18.sl3 Sound U18 L4
funh_l9.rom Game ROM L9
funh_m9.rom Game ROM L9 with nonghosting patch for LEDs
fh_905h.rom Game ROM L9.05 (has nonghosting patch)
I tested all of these and they work. You'll have to match EPROM to the various ROMS 27C020/27C2001 for game roms and 27C010 /27C1001 for sound.
