About a year ago I was looking at Crash Bandicoot timer systems and I found that Crash 3 has a constantly incrementing int32. It only resets if you die.

Left for 2.26 years, it will overflow.

When it does finally overflow, we get "minus" time and the game breaks in funny ways. I did a video about it: https://youtu.be/f7ZzoyVLu58

There's a weapon in Final Fantasy 9 which can only be obtained by reaching a lategame area in less than 12 hours of play time, or 10 hours on the PAL version due to an oversight. Alternatively you can just leave the game running for two years until the timer wraps around. Slow and steady wins the race.

So the invisible 12h timer runs during cutscenes. During Excalibur 2 runs, I used to open and close the PS1 disc tray to skip (normally unskippable) cutscenes. Never knew why that worked.

(I also never managed to get it)

Oh yeah. The sword you pick up in Memoria. The problem there is that the PAL version runs slower; the way PSX games "translated" between the two video systems was just to have longer VSync pauses for PAL. So the game is actually slower, not interpolated

Longer vsync pauses but larger frame time deltas so it’s basically the same speed of play. The only thing that was even noticeable was the UI lag.

So that's why it's called Excalibur 2!

You really managed to make the whole video without making a single "crash" pun? (Those freezes come close enough that you could call them crashes...)

2038 is going to be a fun year.

The easy way to e-Nostradamus predictions:

"See this crash?

I predicted it years ago.

Don't ask me how, I couldn't tell you."

p.s. I had an old iPaq that I wouldn't have trusted to run for longer than a day and stay stable, kudos for that at the very minimum.

I am going to need to see this replicated before I can believe.

Seems to be a PocketPC port of Doom, with no source given or even a snippet of the relevant code/variable name/etc. shown at all.
unixhero · 1h ago
Yes. I think it it seems like it was the os that overflowed, and not Doom in this case.

It's also running on very old hardware, potentially with some electrolytic capacitors that have dried up. And, there's always the possibility that it's a gamma ray [1]!

Not a comment on the post, but I sure wish Jira would load even half as quickly as this site.

Perhaps it's hosted on a disposable vape?

Commenting on my Epic from an LG Fridge.

It takes serious hardware investment [0] to pull that off.

It's not loading for me at all.

Is this a joke because the site isn't loading at all?

At the time of writing the comment it was practically instantaneous for me and the comment was genuine. Now it seems to be having trouble and I'm choosing to retroactively make the comment a joke about Jira ;)

Came back to check this since the tab never loaded. I'm guessing traffic caused some issues?
