Speedrunning is kinda cursed https://www.youtube.com/watch?v=CEQWT9rSkfM

Did you know this? Apparently if you bought a copy of Super Mario Bros. 3 in the US, depending on when you bought it the "bros" in the logo is either aligned left on the label or right.

*If the logo on your cart is aligned right, you can't get a world record under current strategies.*

And until *last year*, nobody realized this was a problem. It was believed the versions were functionally identical.

Mario 3 Version Difference Is Faster VS Slower!?

If this video confuses/bores you: Read this post then jump to 10:19.

In warpless SMB3 runs, there's an early (second world) instance of randomness where a hammer brother can run either right or left, and if it runs left you can skip three entire levels and save an entire minute:

Getting this randomness is important, so players use a "manipulation"– they play in a very precise way (in Mitch's case, literally miming along to a video of a TAS) to get exact random numbers.

@mcc that video is astoundingly insufferable (complete with a baked-in ad) for what amounts to "code changes result in slightly different frame timings, causing rng to be slightly off for manipulation"

@mcc i'm aware, but when i'm literally mashing the right arrow skipping through the video for a shred of actually interesting or useful information and (as you pointed out) it's over halfway into it, idk. maybe some jobs are just bad
