if u r talking for "Street Fighter ||| 3rd strike - Fight for the future", I can ensure u that indeed, this game is NOT playable in MAME yet, although its in mame's list. This happens in many other games, too, like the best ones, DECATHLETE, RAIDEN 2...
PS. Who told u that this game is 1 GB?..Actually the "sfiii3.zip" file is just 139000 kbs
