Enter Training mode, and choose any character and stage. Select "Help on", and choose the smart bomb from the menu. Pick it up, go beside the other player, and throw it at them. Quickly pause the game, then select the smart bomb again. Then, choose only one smart bomb every second. If you select them too fast, you will run out. This will save you a lot of time.
Go to a stage where there is a wall that you can push the enemy up against (for example, Corneria, Temple). Push the CPU character up to the wall. Drop three of the Superspicy Curry items. Move forward to get the curry to move towards you. Duck (hold Down) and get the curry. It runs out after 155% (155 combos). As it gets close to that number, pick up the next curry and repeat. While doing the second curry, a third curry will disappear; pick it up in the middle. It is possible to get 367 combos on Marth by doing this.
