A bit late posting this one but here it is.
Runik has been working really hard to get this done. It is partially tested right now by muddymusic and the game boots but his board set has a graphics fault so at this point it still needs further testing. If you are able to test then please let us know.
Thanks to Runik and muddymusic.
funkycochise has confirmed the above Wonderboy III set to be working.
Thanks to both Dion for providing these files and to funkycochise for testing them and letting me know.
channelmaniac has tested the Altered Beast (317-0069) set as working.
Thanks to Channelmaniac for this.
A lot of these sets still need testing so please let us know if you have tested any.
Thanks
cmonkey has fixed the checksums for the Golden Axe (317-0110) set so the self test should now pass.
Thanks to cmonkey, greatly appreciated.
Shou has confirmed the operation of this decrypted set.
Thanks again to Shou
