I am not good with electronics tbh but why it is not possible to mitm the connection between CD drive and motherboard? As far as I see from 'swap disk' technique outer protection track is not changing depending on game
You can. That's what traditional modchips do, and there's the Rhea/Phoebe which completely emulates that drive via that interface.
Of course, if you sit at that point in the system you have a different set of problems and capabilities. Much easier to build hardware for, but no data output, and of course you need to disassemble the console to get there in the first place.
I was thinking about controlling an outside door unlock button by MITMing the electrical cables going out of it, but realized I have no idea how to go about it. I just need to generate the same signal... I thought maybe someone reading this could have some pointers.
