Hi I'm Stee, I came across your site years ago I believe when modchips where the big thing.
I recently got into messing about with electronics (moreso buying broken things and having a go at fixing them) and came across RDC's amazing pcbs on the xbox one controllers. I'm not sure that counts as mods (I did once attempt a jtag on an xbox 360 years ago) so hoping to soak in and share knowledge when possible.
If you're mental enough to read these things then Cheers!
