Hey James, the patch you gave me gives a crc of E5EADC1E, not B5ABDA07,although it does sound ok (tested with Galford and Ukyo against Kyoshiro and Yoshi). I used ucon.exe for the patching. Is this a different dump? <{POST_SNAPBACK}> Try Lunar IPS (LIPS) thats what I used its a patch which it clearly says that. its a decrypted m1 patch which is now becomes m1d I still have the encrypted m1 in Mame even though its not needed. If anyone uses the decrypted ssv set the m1 crc ADEEBF40 is not needed or used
