To get this one start the english/japanese version of the game and once the cutscene starts hit
then game settings and change the Lives to 9 ,the continues to 99 and lower the difficulty to lvl 1 .
-once the game starts hit
and create an interrupted save data and use it every once in a while as checkpoints , now finish the first level and into the Boss fight (DONT FORGET TO USE INTERRUPTED SAVES TO SAVE LIVES)
-After the boss fight choose the RIGHT PATH! ,You will face some golems and birds ,Just after the platforming section youll find a hut and a cabbage with few bad guys around , All what you have to do is to hit the cabbage and its worth 10,000 points! then let the bad guys kill You and repeat it again till you get the 150,000 ,If all bad guys die when you hit the cabbage just walk forward and let some bad guys chase you back to the hut and kill you there, no worries if you ran out of the 9 lives you have just, hit
to get another 9 lives
hope this helped and thumbs up guys if it did👌🏻
