The Perfect Mario Kart Lap Explained

[@ThatOneSuperCircuitGuy]

The Perfect Reply Explained

[@DavidWonn]

My original intention was to reach the remote section of the track when finding the 9.3 second (and eventually 9.2x") lap version. Skipping a lap was a pleasant surprise, though not entirely unexpected, as the original Super Mario Kart already had known skips of a similar nature. There are indeed multiple other spots in the track which advance you forward in seemingly unexpected ways, even when you intend to play it non-shortcut on rather "standard" paths often played in Vs. / GP mode. Be on the lookout when you are shelled off the track or accidentally fall off while playing against others. The track is quite broken...

[@VinsCool]

To think this whole thing could have been avoided from using double floats for all things related to time calculations, lol Simply amazing. Reminds me of Super Mario 64 converting floats to integers and vice versa for calculating Mario's coordinates on the map, the same sort of weird behaviour occurs over long distances and/or very small numbers rounded up or down.

[@alecrutz956]

to be fair, under normal circumstances you wouldn't run across the wacky long distance bugs in SM64

[@VinsCool]

@@alecrutz956 true to that, it takes a lot of work just to break Mario to this level of insanity haha!

[@psymar]

I suspect it also could have been avoided somewhat if the constant added each frame were single-precision, and I'm guessing it was *meant* to be. It was probably stored only in a #define macro in the original C, where the difference is simply that e.g 3.14 is by default double precision and to get single precision you need to put 3.14f -- and when adding two variables of mismatched types it automatically converts the smaller typed variable to the larger type. Of course, this will still generate a warning or even error on any decent compiler when this new double precision value is assigned to a single-precision variable, unless you explicitly convert it back to single precision first. Which someone probably did to shut the compiler up without thinking for one second about the fact that it shouldn't be necessary and this meant something was wrong.

[@thebeber2546]

I really liked the technical explanations, with the deeper dive the code and how it gets executed. Also it‘s insane, that a perfect lap is possible. If I were the kid described in the intro, I‘d assume literal wizardry.

you actually explained the spheres moving resulting in a .01 time very very well. so well done there and cool vid

[@danieljimenez1989]

A correction regarding the versions. There were three regional versions, Japan, USA and Europe. NTSC was for both NA and Japan (also for most of south America), PAL was for Europe and Australia.

[@VinsCool]

I am pretty sure the version referred to in this case was specifically which ones were running at 60hz and 50hz, so in this case it is indeed technically 2 different timing to accommodate between regions, since both Japan and North American run on NTSC standard anyway.

[@noodlelynoodle.]

@@VinsCool it's still funny to me that half of Japan is 50 hz and half is 60 hz

Their insane attention to detail of the game, how it works, and the application to cause glitches which slowly improves the overall comprehension of each map is amazing. Let alone your ability to understand, interpret, and to then explain the information with comprehensive visual animations and data is a great skill man, keep it up!

[@J3tAlone]

Wow man, been watching for a while and it's incredible how your content has evolved. Your MK stuff is great and this vid in particular is one of the most detailed yet well explained "old game buggy lmao" vids I've ever seen. Looking forward to the next one!

[@SuspiciousLiquid]

Man I’m not a speed runner but you make it so interesting. I can’t stop watching

[@spencerruston406]

Its interesting how the goal is a perfect run, though we've almost never seen it for real with how far off it seems for 99% of games. Something we kind of put off as what happens when we get the perfect run? What happens when you finished a meal to the point the plate has not a crumb left? Both so utterly destroyed theres nothing left to do.

[@psymar]

Usually what happens I suspect is the runner who got it moves on to other categories and other people attempt to tie it. Of course sometimes you also have to do some detailed analysis to prove that it's perfect to disprove multiple claims of better times, as happened with Atari 2600 Drag Race. But yeah I expect if Niftske perfects Super Mario Bros 1, he'll either focus on warpless or try to optimize the PAL version which can theoretically be faster than a perfect NTSC run but is quite difficult to get even close (the current PAL WR is 5:05 though Niftske could probably break 5:00 pretty quick)

Thanks, Brodys been a fan since day one pretty much, he's even helped with a couple videos

[@TetraGalaxyTelecast]

I always wondered about this scenario, and actually seeing it is really bittersweet. On the one hand, the record can never be improved again, the course in terms of speedrunning has nothing left to offer us, but on the other hand, it means we got to witness the entire history of the course before our very eyes (at least in this category) and we got to witness the perfect run.

[@ferociousfeind8538]

11:30 wtf, just store it as an int, of frames since start! then for display, convert to a double-precision float, multiply by the conversion factor (rather than adding the conversion factor every frame, we add 1), do the transformations to get it in minutes:seconds format, and put it on the screen! The converted number undoubtedly has some small amount of possible rounding error, which is why we discard it at the end of the frame, and why we hold onto the int instead since it has no imprecision

[@omegahaxors9-11]

Fun 'fact' PAL stands for Programable Analog Logic; a chip which is common in Europe and rare in America. NTFC stands for NoT Findable Chip and likewise is common in America and rare in Europe.

"stored in the FF section of memory" what? You've confused a few concepts there. The memory location isn't involved. Each polygon (or really, group of polygons) is assigned a type, eg road, grass, ice, wall, or out-of-bounds. The latter is type ID hex FF. (Though, not all out-of-bounds polygons use this type; there's another mechanism that can also flag things as out-of-bounds. I don't fully know how that works.) I don't know why this satisfies the "section >20" requirement. It might be that the section gets set to -1 and misinterpreted as a large number, or these polygons just happen to belong to the right section.
