Link Roundup 3/25/2025

Hello! John “rodneylives” Harris here. Let me quickly explain this before I get into it.

I have an overabundance of games links to present through Set Side B. My usual style of doing this is to pick one of them, then maybe write a bit of text introducing it, maybe a bit of a preview, a media embed of it’s a video somewhere (nearly always Youtube), and that’s a complete post. One a day, for approaching four years now. (SSB launched on April 5th, 2022.)

But working this way, I’ve developed quite a backlog! Not all of them are really worthy of a whole post, maybe, or I don’t have a full post’s worth of context to coax out of it.

So in an effort to clean up my link collections, I think I’m going to make regular posts, maybe one a week, that’s just several things that might be interesting. I post them, my link folder get slightly shorter, each individual person might be interested in one or two items in it each, then we move on to more of the usual kind of thing the rest of the week.

Got all that? Here we go:

1. Dave’s Garage interviewed Commodore 64 chip designer Albert Charpentier three years ago (it’s about an 1 hour):

2. On Mastodon, there’s an account, @everybodyvotes@social,miyaku.media, that posts every poll published on the Wii’s “Everybody Votes” channel, back in the days when Nintendo would do fun, free things just for the sake of doing them. You can even vote on them again, using Mastodon’s polling feature.

3. On Balatro creator LocalThunk’s blog, they’ve published a timeline of its history, from original concept to launch, whereupon LocalThunk earned more money than he had ever had before in their entire life.

4. Back on Youtube, speedrunner Kosmic expresses disbelief on the current state of Super Mario Bros. speedrunning (24 minutes), which is more active than you’d think it’d be for a game that’s so old, and has had so much attention poured onto it.

Kosmic Figures Out How To Defeat Donkey Kong’s Kill Screen

Kosmic is a speedrunner who usually focuses on Super Mario Bros., but he’s reached the kill screen in Donkey Kong before. With some help, he’s figured out a way to complete that game’s “kill screen,” the point where it’s usually impossible to continue.

At Level 22 of Donkey Kong, there is a bug that causes the game to only give Mario (nèe Jumpman) 400 bonus timer points to complete the level. (The screen displays 4000, but that’s caused by a different glitch.) Playing normally, that’s not enough time to reach higher than the second girder on-screen.

However. If the player has Mario climb the first broken latter, then hold down for four frames then up for one, Mario will climb up off the top of it by one pixel. Continuing to do this, Mario can continue to ascend the screen. When he reaches Pauline’s height, the game will declare the level completed and move on to the next screen.

As it turns out, the bonus count on the Barrels screen is tied to the barrels that Donkey Kong throws, and the timing on those is somewhat random. If DK is slow at emitting those rolling obstacles, rarely, that will give Mario just enough time to reach Pauline at the top, and advance to the next level.

Doing this physically is essentially impossible. The player would have to waggle the joystick extremely quickly (and loudly), yet with the precise timing to consistently raise Mario’s position, to get him up the screen in time, and even if that worked, he’d still have to be lucky enough that Donkey Kong was slow at rolling barrels. But in emulation, with tool assistance, Kosmic managed to get to the top and finish the level. Then using other tricks and glitches, he managed to finish the next three levels (Elevators, Barrels again and Cement Factory) too, before his luck ran out at the next Barrels screen and he was unable to continue.

Here’s his 29 minute video explaining his feat. Or, if you’d like to avoid the general description of what this means, you could start at this point 11 minutes in.
