Folds have water ratings but no (or worse) dust ratings. So you can use them in the rain but be careful in a beach, wood shop, etc.
The first number in the rating is dust resistance, and the second is water resistance. So an IP 48 phone (new Samsung folds) has the same water resistance but worse dust resistance than an IP 68 phone (e.g. S25). IP X8 means there is no dust resistance but it is water resistant. IP 6X would be the other way around.
I think there is more evidence pointing to it being the runner’s cartridge or N64 having a hardware fault that caused it to happen. If I’m remembering correctly the runner said they had to frequently reset their runs because their game would crash for no specific reason, and they would reinsert or adjust the cartridge to get it working again.
