how people modify chip memories that shouldnt be modified?

655 views

Like everyone else on the internet ive seen people running doom on some wild stuff

But i never comprehend how people manage to get it on the memory of things that dont have external acess to their memory, like the people who managed to run it on a threadmill

Like, how do you change the data on those chips that dont give you acess directly to their data in any simple way like a usb connection?

If you want a really really nerdy video about that I can recommend [this dump of a wacom drawing tablet firmware](https://www.youtube.com/watch?v=TeCQatNcF20). That way you can get access to the raw firmware that shouldn’t be readable.

This concept of intentionally disturbing the power supply clock cycle perfectly can be applied to a lot of devices and can result in the weirdest malfunctions, including total failure of protection routines.
