SEGA Superstars Tennis

My friend, DangerSlave, and I, were going for this achievement. Using the previous solutions, the achievement never popped. By observing other players who were on the superstar channel at the time and had the achievement, we came to the conclusion that by prolonging a match the achievement will pop. As soon as we played the match and forced a 5th game, the achievement popped for the both of us.

Achievement pops when your game is good enough to be put on the Superstar Channel.

Alternate wins forcing a game 5 and the achievement is yours.

For this achievement start a ranked match and try get a friend with you, now once the match starts whoever is serving wins the match by hitting 4 aces then the other hits 4 aces and so fort. Do this until you go to a part that will be like a sudden death match which you'll have the chance to score 1 point at a time, whoever has the ball will get 2 shots then it will switch players and the other player will have 2 shots, now once there just keep scoring points until your at 9-8 and it will unlock and never be more than 1 point ahead.

This will unlock in the match as well and this was my time that it took me by doing this method: 2 minutes 58 seconds. So very quick method.

Also by doing this you don't need to use the Super Star's Channel to look at the match to unlock this.

This achievement unlocks randomly pretty easily, however if you want to boost this, here's what you need to do.

You need 3 players (including yourself) to start. You set up a ranked match and play the game. You can either Ace the game or actually play a good back and forth (might as well go for Sega Rally if you don't have it) with the 2nd player, and win the match against them.

After the match, have the 3rd player browse and continually refresh the HIGHLIGHTS CHANNEL as you create a 2nd match to play against the 2nd player. During the 2nd match, your previous match's highlight should have appeared on the highlights channel, and as long as player 3 watches that highlight, the achievement should unlock for you.

NOTE: The highlight MUST BE UNDER YOUR NAME. If it's under player 2's name, the achievement will go to him. So this must be done at most 3 times if boosting, to help all parties involved (if they need it).

*EDIT* - According to Spartan's solution, if you prolong a game to 5 matches (by alternating wins), you automatically unlock this achievement. Since I haven't confirmed it myself, I trust him and the people that voted his solution up to vouche for that strategy. Try it if you do not want to try my method listed above.

Hope this helps.
