Easy way to get this, the 200,000 and 300,000 achievements is to use the continue option. Make sure before you start the game in Original mode you insert more than 1 coin (not literally just keep pressing the insert coin button). When you have used your 3 lives just click continue. Your score keeps rolling over, score over 300,000 and get all the cheevos in one play through.
My first quide, any feedback just let me know. Not by negatives votes though hopefully. :)
