I know this is an old thread, but just curious, now that Donkey King is added to MAME, the ROM's out there seem to be missing a PROM file called 82s129.5g. What does this PROM actually do? I see my Donkey King board has an 82s129 PROM chip at location 5G, but I don't have a way of reading it (my EPROM burner only does EPROM's as far as I know). I created a fake one using one of the other PROM's and the game seems to play OK that way (although it complains about the checksum). Not asking for the file, of course, just wondering what it's for
