If you do somehow manage to beat it, it will go straight back to level 1. Pac-Man's kill screen doesn't automatically progress to the next level despite the lack of dots. (The nine dots can be consumed again on each life, but you can't get enough lives to make it to 244.) This also explains why Ms. 122 on the left half plus the mere 9 on the right half is 131, not nearly enough to progress. The right half of the screen contains only 9 dots. The game checks for 244 Pac-Dots eaten by Pac-Man for the level to end. The result is the garbled mess on the right side of the maze, because the screen memory starts with the bottom, followed by the columns from the right side. The level counter starts with 0 internally, but for calculating the fruit counter it adds 1 however, because of overflow, adding 1 to 255 would result in 0, and the game tries to count fruits from 1, causing the game to attempt to draw 256 fruit to the screen until it overflows to 0. The level counter in the original Pac-Man is stored as an 8-bit integer, meaning the highest value it can hold is 255.
