![]() ![]() No matter what the player does, the "Pac-dots collected" count will never be large enough, so the game cannot progress and ends here. This attempt to draw 256 fruit on the screen, overwriting many other items - such as the precious Pac-dots required to complete the level - whilst doing so, is the cause of this dramatic glitch. The loop will dutifully draw fruit on the screen repeatedly until it has finished, by which time it will have drawn "level number + 1" fruit, which is fine when the level number is less than eight, but not when it is 255. but subtracting anything from 0 will cause it to underflow to 255. The fruit-drawing loop will then proceed to draw a fruit, subtract from the counter, check if it's equal to 0. LD DE,#3B08: Load the address of the cherry into DE.JP NC,#2C2E: Don't jump to large-number fruit handling code.INC A: Increment 255 to 256 - this overflows to 0.even if it's 0! But if the level number is 255, the implementation's main flaw is exposed: Tornado, Giant and much more Stay ahead of the super-villain lurking in PAC-MAN since the beginning: The Glitch. ![]() This code works fine if the level number is 1, 2, 3, 4. (The assembly code is reproduced and explained in detail here, which also includes a patch to remove the glitch.) LD DE,#3B08: Load the address of the cherry into DE. The game ends if Pac-Man comes into contact with a ghost or falls behind and is consumed by a chasing glitch at the bottom of the maze.The bug was originally analyzed and documented by Don Hodge on his website, where. It is commonly referred to as 'Split Screen' due to the right half of the screen looking garbled, while the left half is still intact. JP NC,#2C2E: If not, jump to large-number fruit handling code. Did u know in the original game when u type true end on a computer it will noclip u to this level or reach level 256 it glitches then u will know u beat the. Perhaps one of the most infamous bugs in gaming, the game renders garbage at Level 256.LD A,(#4E13): Load the level number (at memory address 0x4E13) into A.The way the game calculates the number of fruit to draw is as follows: The glitch was defined as making " half the machine break down at the 251st rack".There are only seven fruit in Pac-man. ![]()
