Executing a 125-input combo in Street Fighter IV seems like a challenge that should pay more than $US50. Nonetheless, it's out there, and if you can do it, a legal tender picture of Ulysses S. Grant is yours.
This combo spans 125 button inputs, 126 hits and 661 damage. Reproduce it by hand - without tool assistance, infinite meter or button-binding - and you win. Your video clip must show the screen and your hands in the same single-shot throughout. The bounty closes on October 27, and a winner will be declared sometime in the following week.
