I theorize "Lap 5"/"Lap 8" is a hint that they considered Baby Park for MKWii, even if that did not happen. It would explain the extra laps not seen in other cases.
Funnily enough, the Lap 4 sign (and a Lap 3 one that isn't shown in the video) *was* used for an online tournament where you had to complete 5 laps in a modified version of DS Twilight House
Yeah they textured every number that Lakitu could possibly display. What’s weird though is that the end results only go up to Lap 3, the other laps will just use different text.
they probably used it for development because it was from the NGCMK game, and its also the smallest so it would be the quickest to import and get working in the game
I just want to point out why the maximum is 8. During the Nintendo WFC days, there was a tournament in which you had to drive 8 laps on Twilight House. This is the only point in the game where you have to drive more than 3 laps so there’s no point in adding a 9.
It'd be wild for the people in charge of a website filled with people breaking the rules of games to finish them as quickly as possible to say "no you broke it too much"
@@WannabeMarysue I would be shocked to see that they were so incompetent that they thought they had to spent two paid weeks driving backwards to replicate this bug.
19:09 I suspect the 8h 20m limit on the race timer is supposed to account for people hitting the lap limit on each lap on tracks with 5 laps. (8h20m = 500 minutes, that's only 5 milliseconds more than 5 * 99:59.999) Given that there are textures for Lakitu's sign to indicate laps 4 and 5 (actually up to 9 but they aren't programmed to appear), and the fact that the previous Mario Kart games had tracks with more laps, it seems that some tracks would have 5 laps in this game too.
In fact, the 5 lap thing itself isn't theoretical. There were 2 different tracks that *did* have 5 laps, but are unavailable now. These are the GCN Cookie Land and DS Twilight House tournaments. :)
19:16 This is actually five times 99:59.999. Five times a hundred minutes is 500 minutes, or eight hours and twenty minutes. Considering that the maximum amount of laps Lakitu is capable of showing corresponds with the multiplyer of 5, this further indicates that tracks with five laps were planned but ideas where scrapped. Very enjoyable video! You took an obscure yet interesting topic and explained it in an easy to comprehend and simple to follow way. The amount of dedication is unmatched. Keep up the great work!
Its a wii game, there are ways to break it. Things we thought incredibly impossible before have been achieved. It'll take some serious ingenuity, engineering and totally breaking the game, but it could be possible. Like, what if there was a way to freeze the time counter before it reached maximum?
hey there, I wanted to correct something, namely about floats, and I'll continue watching the video after writing this. The wii does NOT have native floating point number capability, and the behaviour exhibited seems to be correlated with a programmer-defined fixed point number, which can easily be handled by the wii's rather advanced integer mathematics calculation. Dolphin specifically calculates and presents these numbers as a float on modern x86_64 hardware as x86_64 lacks the instruction sets for advanced integer and fixed-point mathematics that the wii does, and therefore cannot perform them as quickly. It's entirely likely that this specific difference between the wii and other PPC consoles of its era led to some undue confusion.
With lap 8 being the maximum on display, could it be a remnant of NGC Baby Park, which had a lap count of 8? Is the code for the lapcount in Wii the same as NGC?
I think it has to do with the number of binary values it reads, since it wouldn't read more than 10 for a single-digit counter. 8 is the highest base value in the binary system, and they don't need the 9 value, they just stop at 8.
@@magicowlofbacon9416 it makes the most sense for this to be the case, as you can use half a byte + 1 to display 8, and this is what i want to guess is happening
Real quick - the 8 hour, 20 minute cap makes a little more sense when translated to minutes. 8 hours and 20 minutes is 500 total minutes - and so, if you had a **5 lap race,** the timer would fully max on every lap at that point. Lakitu caps out at Lap 5 as well, which makes me think this was a failsafe implemented early on, when the devs decided they only wanted to support lap counts of 5 or less.
I have a very half-baked theory as to why the timer is capped at 8 hours and 20 minutes. But I think it makes sense, even if I have no proof: 8 hours and 20 minutes is exactly 500 minutes, or, 5 laps worth of max time laps. And given that Lakitu caps out at 5 laps there's a good chance that at some point during production they decided that they weren't going to go over 5 laps (perhaps leaving the door open for a shorter track like baby park), and they figured a total time past the max out for all possible laps wasn't worth tracking, so, to avoid having to even think about weird data issues that might happen if the game is left on for too long, they just decided anything past that was an automatic worst time possible on all laps.

I think the reason for the timer value given is that that is the highest value that can be displayed in the UI, even though the actual value in memory is much higher. You would have to overflow the time value to get back to 0s, BUT, if you time it just right, you might even be able to get a one frame time by starting a frame earlier than 0.

"float" means floating point decimal. It means that in the data representation of any number, which bits inside the variable represent the integer part and which represent the decimal part can vary. If we find out that the first 2 bytes of the 4 byte variable are strictly for representing the integer part and the rest is for the decimal part, that means we have a FIXED point decimal. More accuratly one in the Q16.16 format.

Can confirm: modifying the game to make tracks last 9 laps will end up displaying 8. After completing lap 8, the display will not change, but one more lap will need to be completed before the race ends, if that's the required lap count for the track.
Originally you needed to complete 5 laps. On the first Mario Kart, which this track is from, you did 5 shorter laps. It only changed to 3 in the later versions that had "longer" tracks. Lap 5 was always the standard until they changed it. So, it's definitely not weird to see Lakitu hold a Lap 5 on a Super Nintendo track. It always happens, every time you race on Super Nintendo.
"This might seem super strange..." Not at all. Many compilers have a stroke if the data types don't match, so forcing the 4-byte to behave as 2-byte for the sake of doing math with them makes sense.
The 8:20 hard limit comes from the fact that 99:59.999 for 5 laps in a row is 5 ms less than 8 hours 20 min. Beyond 8:20 the run is longer than 99:59.999 for 5 laps in a row so the devs considered anything beyond that to be useless
it's sorta like the largest number you could represent in base 10 with say 3 digits is 999 so 1 + 999 = 1000 => 000 would be an overflow (9 being the largest digit in base 10) similarly 1 + 1111 1111 = 1 0000 0000 => 0000 0000 (1 being the largest digit in base 2) underflow is just the reverse of this, 0 - 1 = -1, but you could think of that as -1000 + 999, and since the thousands digit is ignored (there's no space to store it) you just would get 999
I Really Love how Deep you go with your Explaination and Visually allow us to get a good understanding of this awesome Project. Have an awesome Day. Dan
19:10 The cap of 8 hour 20 will be because that is the length of five laps of 99:59.999. There is no point is counting higher than that as all laps will still be displayed as the max time.
Funky Kong on the Flame Runner driving endlessly on a short, flat track, with only ghosts for company. The background, a black void. The timer, long maxed out. Lakitu keeps telling him he's going the wrong way, but Funky is searching for something beyond logic. If purgatory exists in Mario Kart Wii, this is it.
Let’s you you’re on lap two, in MK7 If you drive through the course backwards, internally, the game’s lap count will go down even though it doesn’t show you, so it could say you’re in lap two and you rival is in lap one but you could be in second place while they are in first
I think I might know why they set the max amount of laps lakitu shows to 5. In the original super Mario kart, there were 5 lap tracks because they were so small. Your discovery may mean that at one point in development, they planned to have at least one 5 lap track
9:56 I don't know why I'm bothering to correct this, but Titanic Monarch Act 2 is from Sonic Mania, not Sonic and Knuckles. Love your videos! This is insane!
19:19 500 minutes, as many Pokemon Go players will know; why they chose exactly 500 over (ex.) 1000 is not obvious, but it's still a fairly nice round number :)

The things we do just because we can
The 8:20 hard limit comes from the fact that 99:59.999 for 5 laps in a row is 5 ms less than 8 hours 20 min. Beyond 8:20 the run is longer than 99:59.999 for 5 laps in a row so the devs considered anything beyond that to be useless
I’m too stupid to get my head around bytes etc., but this was absolutely fascinating!
it's sorta like the largest number you could represent in base 10 with say 3 digits is 999
so 1 + 999 = 1000 => 000 would be an overflow (9 being the largest digit in base 10)
similarly 1 + 1111 1111 = 1 0000 0000 => 0000 0000 (1 being the largest digit in base 2)
underflow is just the reverse of this, 0 - 1 = -1, but you could think of that as -1000 + 999, and since the thousands digit is ignored (there's no space to store it) you just would get 999
@@sage5296 I understand the basic concept of the overflow/underflow stuff, but thank you anyway for the explanation.
I Really Love how Deep you go with your Explaination and Visually allow us to get a good understanding of this awesome Project.
Have an awesome Day.

great video as always man, over a decade in were still finding ways to break this silly game
19:10
The cap of 8 hour 20 will be because that is the length of five laps of 99:59.999. There is no point is counting higher than that as all laps will still be displayed as the max time.
The last time I drove backwards for two weeks the police were pissed about it.
Just trying to reach officer, underflow
And to think... this entire mess could have been avoided with just a few additional lines of code:
if (lapcount < 0) {
lapcount = 0;
}
Funky Kong on the Flame Runner driving endlessly on a short, flat track, with only ghosts for company. The background, a black void. The timer, long maxed out. Lakitu keeps telling him he's going the wrong way, but Funky is searching for something beyond logic.
If purgatory exists in Mario Kart Wii, this is it.
Me: *expecting Mario kart driver to actually drive backwards*
Pretty interesting! Excellent video! Thanks for uploading!
This is crazy - well done, amazing video!!
"hold on, Im gonna be done playing soon"
Lap 4, the cursed unholy lap
Let’s you you’re on lap two, in MK7 If you drive through the course backwards, internally, the game’s lap count will go down even though it doesn’t show you, so it could say you’re in lap two and you rival is in lap one but you could be in second place while they are in first
I think I might know why they set the max amount of laps lakitu shows to 5. In the original super Mario kart, there were 5 lap tracks because they were so small. Your discovery may mean that at one point in development, they planned to have at least one 5 lap track
LAP LAP LAP LAP LAP LAP LAP GET DRIVEN GET DRIVEN GET DRIVEN GET DRIVEN
Woah there
@@Loafoftime WHOOOOOOOAHHHH
Pannoek builds speed for hours.
You build underflow lap for weeks.
9:56 I don't know why I'm bothering to correct this, but Titanic Monarch Act 2 is from Sonic Mania, not Sonic and Knuckles.
Love your videos! This is insane!
19:19 500 minutes, as many Pokemon Go players will know; why they chose exactly 500 over (ex.) 1000 is not obvious, but it's still a fairly nice round number :)
