Pac-Man Championship Edition DX - How to get 'No Mistakes' and 'No Bombs' Achievements
This achievement requires you to complete Score Attack 5 minutes without losing a life. I did this in the first level of the game (Championship 2 Score attack 5 minutes). Set the game to beginner difficulty and start the game. DO NOT eat any pac-dots or pass by any ghosts. Just stay in a corner. After about a minute, a red ghost will come to try to attack you. Don't let him touch you or you will lose a life. If you did not pass by any ghosts, he will be the only ghost and will be fairly easy to avoid. If you set the game to beginner difficulty the game speed will be at 1, which is good. The timer does not go down any faster or slower on other speeds and difficulties. If you get caught in a jam, use your bombs (unless you are also trying to get the achievement No Bombs). The achievement will unlock after you finish the level. You do not need any points to get this achievement, as I got it with 0 points.
