This is one of the few games that are almost impossible to receive a full 1000. Only a few people on this site have actually achieved this. All but one of the achievements are fairly easy to obtain. The one that most people do not have and never will is “To be this good takes AGES”. As the name states: it takes ages to get this achievement. Also note that AGES spelled backwards is SEGA.
Introduction:
This game requires only one playthrough but it also requires that you play several tennis matches not related to the main game. These matches include online achievements and co-op achievements. These are very easy to obtain, especially when boosting with other people in this thread.
Walkthrough:
Step#1: To start off, you will want to play through the game’s story mode. Though it doesn’t have a plot or any type of story line, it is a sequence of events therefore it is to be called a story mode. The story mode for this game is known as SuperStars mode. This area of the game is fairly straightforward and doesn’t require a lot of guidance. Simply start a new game and play through every mini-game, tennis match, and tennis tournament. Each stage requires that you meet certain criteria before you can proceed to the next level. SuperStars mode does not require you to play it in one sitting or one straightforward line. You can exit a level at any time you wish and your previous data will still be saved. Upon completion of SuperStars mode, you could have obtained a total of 35 achievements which is worth 780. You most likely will not have this unless you are very skilled at this game. Continue this walkthrough to learn how to obtain missing achievements.
Step#2: Now that you have completed SuperStars mode, you are ready to move on to co-op mode. There is only one achievement that requires you to be in co-op and that is “Party Time”. This achievement is very simple to obtain.
Step#3: This step is for Tournament mode. Start off by playing a new tournament via the main screen and select the character you wish to play as. Play through all tennis matches with at least a score of AA. When you defeat the last stage of the tournament, an achievement will unlock. If you have a least a score of AA for each match, then you will be sent into a bonus match against Dr. Eggman. He is very hard to beat but keep trying and/or restarting the match until you beat him. Upon completion of this a second achievement will unlock.
Step#4: This is the final step. Now you are ready to obtain all of the online achievements. This is best done by boosting with another person and should only take about 45 minutes to unlock all of the achievements. Refer to the achievement guide for instructions and this thread for boosting.
