Im trying to run killer instinct on an older version of MAME. I used chdman & hdcomp to extract and recompress the chd to older format. The game works, but the problem is mame cries that it’s the wrong md5. The problem with this is that you have to press a key to get passed the error. Is there a way I can update the md5 or maybe just make mame skip the error instead of waiting for input? Really would appreaciate any help on this it’s been driving me crazy.
