      regular ECC can only protect against single bit flips though. If more than one happens to flip at the same time you're fricked

        That's about as likely to happen as getting struck by lightning then eaten by a shark while having a winning lottery ticket in your pocket.

        ECC mainly.

        You're not fricked if you accept that the machine stops on two bit errors.

      you're just fricking moron.

      and not a single word of it is true.

      how do they know it was le heccin space beam though?

      easy. you just lie.

      I recall the video mentions that the aforementioned speedrunner did have, with certainty, a problematic cartridge.

      probably hacked cartridge. it's not like these speedrunning organizations get gamers to submit dumps of the roms they're playing. it works on a completely "trust me bro" basis when it comes to real hardware. as long as they see you playing it on video that's all that counts.

        >probably hacked cartridge
        Now that you mention it... isn't it pretty trivial to hack a rom to manipulate some RNG to just make it appear as if you got really lucky? You'd just have to make sure there isn't some way to predict RNG results via gamestate or some shit.

    You guys don't believe this right? You'd need to have really low IQ to actually believe that a space beam flipped the bits on some random guys video game.

      I mean, you're getting pelted with them right now. Like, right now. Your DNA is being rewritten by cosmic rays with literally every breath.

      Happens occasionally, so it's not entirely impossible, but its very rare and older chips with thicker conductors inside are more resilient to it.

        The footage of the original assumed bit flip couldn't have been from an ionized particle, it was likely the fact that the runner had a faulty cartridge he had to move around, which is likely to flip many bits at once at the slightest of movement from the cartridge

          >which is likely
          tilting a cartridge or making a setup to test a simple cartridge contact is very easily replicable, just like goldeneye geddan glitch, so you should be able to replicate it.

      Cosmic bit flips are extremely rare, and ECC RAM handles them regardless.

        >extremely rare
        if by rare you mean "happens several times a week or even day on every PC in the world" sure
        one bit isn't usually enough to matter, cosmic rays aren't the only way to flip a bit, and there's loads of error correcting code

            It has probably happened to everyone in this thread today on at least one of their devices.
            It was one flip per 256 mb per month in the fricking 90s when transistors were a fraction of the density. It's only gotten EASIER to flip a bit with time. It will only continue to get easier.
            DDR5 is basically ECC RAM, so it doesn't matter as much. But it will happen more.

            Why don’t you go learn about semiconductors and what a particle can do to them and then you might understand.

    plastic apparently shields these type of radiation from space. or better yet you could make a underwater lead-roof bunker but then you'd be exposed to radioactive gasses and particles/stones beneath so the best thing to do is just get a fricking thick slab of plastic and put it on top of your PC case or storage devices.
