However this was at a cost as the boot ROM bug that allowed homebrew enthusiasts and tinkerers to tamper with their switches was fixed for good. This of course upset many owners of the newer Switch iterations, and left people wondering whether or not they could ever enjoy homebrew on their 'Mariko' Switches in the future.
That future might not be too far away as developer @SciresM has successfully managed to dump the keys of the firmware on said units. In his YouTube video he showcases how this process was achieved:
SciresM said:We have the Mariko firmware keys and fully label Mariko trustzone.
Even if slim, these early developments show that there is a possibility of running homebrew on the Nintendo Switch 'Mariko' units, and getting TrustZone access on the system.
