Reverse Engineering ps2 slim in 2025

i got a ps2 from a front the first thought when i got the thing in my hand was if i can port linux on it or not, I know people have done it and i am 20yr s late but i still wanna figure out how to reverse engineer this piece of tech and understand in and outs of it.

For past 2 days i'm running on 3 cans of redbull trying to do the same thing due to a faulty mod chip which was installed on the board it wasnt booting properly so i sat down with my multimeter going through every pin to see if every component is working and realised the whole video processing chip is bad but i still stayed up last night talking to diffrent reapir man i found from google trying to figure out whats the issue and one guy told me he would send me on for dirt cheap.

So how to do this properly this time? How to learn proper reverse engineering? How to understand how the CPU works? how to understand how the EE works? how can i port linux or DOOM into it..
