I had a sudden thought which hit me. The 12:43 is s secret and i think ( ihope) how to unlock it. And you might think i am crazy or you might have tried it allready. Here goes.......On the Character Select screen each character has a Difficulty level on their Status, and all there levels are 1 -> 5. How about using the character who has 1, and the next character who has 2, the character who has 4 and next 3, but you must complete the game 4 times without reseting the machine, or either you can switch characters during a match in the 12:43 order. Just note this, add these numbers which makes 10 matches. The Character with the Level 1 ( play one match ) and switch to another character who has level 2( play 2 matches) and switch to another character who has level 4 ( play 4 matches ) and switch finally to the character who has Level 3 and finish the game with that guy. All this is worth a try and very simple and overlooked.......i just hope this works. Oh yea and keep the timer to 20 secs and make sure you finish the game within 15 minutes, no more than 20. So try and dont blast me, we all want to know the secrets to this game.
