bootrom is basically the bootloader in other devices, the 3ds arm9 process is then started after bootrom verifies boot0 is signed(its basically the OS you have installed booting up). The otp is used to sign the arm9loader and what a9lh is is overwriting it to something more useful lol. More info here: https://www.3dbrew.org/wiki/OTP_Registersso essentially only system patches are achievable (aka things like luma3ds) using otp? but the bootrom key would be like actual firmware (all the way down to arm9 arm7 arm11) anything it can handle?

so we could technically patch the boot0 to load our otp automatically?
