I can back that up - several System 22/23 games we bought for dumping the boards came with the composite encoder to use with the Mitsu TVs (which means that NTSC emulation is actually arcade-accurate, frighteningly enough). That little encoder board's not a bad thing to base a homebrew supergun on though
