Unfortunatley if the master you want to see playback has recorded in "dos" mame in those versions you may have to find a computer that plays "dos" mame, i.e. win95 or win98 computer to get it to work.(posted 9171 days ago)It is always best to playback in the same format as was recorded, a recorded with m37b7 (dos) recorded with no sound, maybe ONLY be playbackable with m37b7.exe -playback inp.inp -soundcard 0
Luckily you can download the mame version for nearly every recording made here, but NT doesn't run dos mame (at least i don't know anyone that has gotten it to work.)
Which recording are you trying to get playback? If the score is old and colored "green" and not confirmed "orange", it may not be playbackable for anyone...
