Always win
When you load your game and start playing a match, remove the memory card. If you win a frame, the "Memory card missing" message will appear. Insert the memory card and you will be prompted to save. Save the game. If you lose a frame, do not insert the card, but instead quit the match. Answer "No" to saving and go to the player option where you can load the game. Reinsert the memory card, and load the game to start at the end of the last frame you won.

More points for player stats
When you are in qualifier rounds, go to "Tour Length" and select "Normal". This will set frames to best of three, and give you 2 points to spend each time you win a match. When you get into the main event, change it to "Short" again. Note: Short tour length matches in a qualifier round only get you 1 point to spend.
