Hi all great job everyone has done with posts, very helpful and informative. Please forgive me if someone else has already asked this question but I was unable to locate it. I would like to use my Wiz for mame emulation but am concerned with flashing to the latest bios when I receive my wiz tomorrow for the simple reason of performance issues. I saw a post stating that mame became slower after flashing to the latest bios. Is this true? If so which bios version is best for mame performance? I am new to this community and thank you for your help.
