There is another Karnov rom set - a bootleg version of the Japanese roms with
|

the Data East copyright removed - not supported because the original Japanese

roms work fine.
|

^^ This should be added (DH, 30/03/11)

One of the two color PROMs for chelnov and chelnoj is different; one is most

likely a bad read, but I don't know which one.
