I want to throw some info out there because it seems that a few people are finding that these patterns don’t work the same when they attempt it. 1. A lot of Pac-Man’s you see in collections are NOT the same rom as the arcade version. You need to be playing the arcade rom for these patterns to work. They may have been created from the ground up or are using a modified version of the rom. 2. You cannot slip up the pattern even ONCE. It will mess up the timing because these patterns are very specific Edit: there are also things like the Pac-Man pocket player that try to imitate the original version on different hardware. The pocket player in particular seems to be a Sega Genesis recreation. You can usually tell when it isn’t an arcade rom because it’s supposed to sound exactly right. If you notice a sound effect in the game sounds different than what you’re used to, you’re more than likely not playing the genuine version

Yes, if the program is different, I wouldn't expect them to work the same.

42:08 The game thinks were *on level 255* because the *level counter* started at zero, *fruit counter* at one. Because the fruit counter is 0 on level 256th, here's short explaination: The fruit counter was suposted to always draw seven fruits. Each number has their own case: (I replaced Galaxian with a monster coz emoji doesn't exist) Level 1 = A (⬛⬛⬛⬛⬛⬛🍒) Level 2 = A (⬛⬛⬛⬛⬛🍒🍓) Level 3 = A (⬛⬛⬛⬛🍒🍓🍑) Level 4 = A (⬛⬛⬛🍒🍓🍑🍑) Level 5 = A (⬛⬛🍒🍓🍑🍑🍎) Level 6 = A (⬛🍒🍓🍑🍑🍎🍎) Level 7 = A (🍒🍓🍑🍑🍎🍎🍇) Level 8 = B (🍓🍑🍑🍎🍎🍇🍇) Level 9 = B (🍑🍑🍎🍎🍇🍇👾) Level10 = B (🍑🍎🍎🍇🍇👾👾) Level11 = B (🍎🍎🍇🍇👾👾🔔) Level12 = B (🍎🍇🍇👾👾🔔🔔) Level13 = B (🍇🍇👾👾🔔🔔🔑) Level14 = B (🍇👾👾🔔🔔🔑🔑) Level15 = B (👾👾🔔🔔🔑🔑🔑) Level16 = B (👾🔔🔔🔑🔑🔑🔑) Level17 = B (🔔🔔🔑🔑🔑🔑🔑) Level18 = B (🔔🔑🔑🔑🔑🔑🔑) Level19 = C (🔑🔑🔑🔑🔑🔑🔑) Level20 = C (🔑🔑🔑🔑🔑🔑🔑) (Fruit list is 20 elements long: 🍒🍓🍑🍑🍎🍎🍇🍇👾👾🔔🔔🔑🔑🔑🔑🔑🔑🔑🔑) Mechanics of cases: A - If the level is at most 7, then draw fruits from 1 to level. Then, erase 7-level fruit spaces. B - If the level is beewen 8 and 18, then draw fruits from level-6 to level. C - If the level is at least 19, then draw fruits from 13 to 19 (always seven keys) Well, 256 was suposted to be in Case C, because 256 ≥ 19. However, the machine was 8-bit and it treated as zero. In 8-bit system, 0 = level 1, 1 = level 2, and so on forever. 8-bit values can be writed at range from 0 to 255. 00000000 is 0, when all bits are turned off, and 11111111 is 255, when all bits are turned on. Even if we try to add 1 to 255, all the bits will get back to zero, because 256 requires a ninth bit, which doesn't exist here. After passing 255th level, the fruit counter was of course 255, but after the increment came 0. Because it was less than 8, the Case A was applied to happen. The machine has in general 1024 bytes for graphics ($4000 to $43FF) and another 1024 bytes for colours. ($4400 to $47FF). The memory was starting from the right, instead of left. Firstly ($400 to $403F) there's a fruit & live counter. The maze is stored at beetwen $4040 to $43BF. The memory was ending at ($43C0 to $43FF) when the scores were displayed (1UP; HIGH SCORE; 2UP) What does it mean to start at 1 and end at 0? It means to draw fruits until it overflows back to 0. When we try to draw 256 fruits, the first 13 are good. 14th isn't visible. 15th's up half isn't visible. Fruits 15th to 30th got glitched down half (start of maze drawing). 21st to 30th are scrambled. 31st onward are now drawn on the maze. After that, seven blank tiles were drawn.

“Short” explanation

@kilroy987 6 ай бұрын

20:27 Regarding your point about the random fruit time - there is a set of incrementing timers that are used to pause when eating monsters and expire the fruit. They reset to zero at the start and restart of any level. They are tracked by hundredths, tens of hundreths, and seconds (at least, those are the only ones I'm concerned about). Hundredths are incremented each frame and only count to 6, which then increments tenhundredths to 10, which then increments seconds. If tenhundreths is currently 9 and hundredths is currently 5 when you eat the fruit, the next frame will increment seconds which consumes a full second of fruit time, resulting in the 8.91 seconds you mentioned. It isn't exactly random, because on a perfectly repeated pattern, the fruit will always disappear at the same moment. (at least, this is what I estimate, having studied the arcade disassembly to attempt my own clone). Update: I just noticed your detail on the timers at 51:21. The same group of timer bytes are used for the eaten ghost pauses and the fruit timer, so I presumed they are always the same for each pattern. If the fruit timer (which uses seconds and is 'random' from the value of the tenhundredths timer) is variable when the eaten monster timer (which uses tenhundreths and is 'random' from the value of the hundreths timer) is not, that means I have more studying to do. I assumed they were both reset with a level, because the monster pause timer is so critical for a pattern to work, otherwise the monsters get out of position as timers expire while eyes are running back to the monster box.

See the outtakes, where I show eating the fruit at one iteration of the pattern, but it disappearing before eating it in another iteration. I really liked that pattern, but I think it cost me 5000 points 1/10 of the time.

@kilroy987 6 ай бұрын

@@brianandcindy1 I trust your results. I was just thinking that if the fruit timer is random, then so is the eaten monster pause timer, and that can significantly affect pattern success. I'll keep looking at it. Thank you for the detailed video!

@kilroy987 6 ай бұрын

I tried out a pattern on level 1 in Steam Arcade Pac-Man. The fruit keeps disappearing at the exact same time. But maybe that version isn't coded the same as what you were playing here. Also, I realized that the first monster eat timer could be random, but once its timer is consumed, it has lined up the timer for the rest of the monster eats for the rest of the level. The first monster eat doesn't matter - the 2nd, 3rd and 4th ones matter for timing. Since the first eat lined up the timer, the rest of them are now lined up properly. That's my current finding. I'll keep looking.

Sort of....you can finish the level that way, and the fruit will return to cherries, and a couple of half keys will still be there for 1 more level, but everything else will be the same as 255.
