Unlimited skill points
Enter "Create A Fighter" mode. Select "Load Fighter". Highlight a fighter and press Y to preview him. After your fighter loads, press X to display his stats. Press X again to hide them. Press A to load your fighter. Edit his "Fighter Skills". The previous stats will remain the same and you will also have an extra 3,024 points to spend on skills. Use them, then back out to the "Finished" option and select it. After the game saves, go back to "Create A Fighter" mode and repeat the process as many times as desired. Note: The "Strength", "Speed", and "Cardio" values cannot be raised with this trick. This also cannot be done in Career mode.
