Preloader also depends on the System Menu IOS and runs on the PPC side, so it only saves you from brick problems that affect the System Menu (although these are pretty popular, so it’s still significant) – it won’t help for anything affecting IOS. Of note is that BootMii-boot2 doesn’t require anything on NAND that is dependent on your NAND keys, so the parts of NAND that are required are exactly the same (at least among Wiis with the same boot1 version). Update resistance: BootMii as boot2 is likely to survive updates, because it’ll only be overwritten if boot2 is updated. BootMii as IOS would be overwritten with a System Menu IOS update, and Preloader would be overwritten with a System Menu update, both of which happen often and are pretty likely.

Interestingly, BootMii as a regular IOS is more likely to survive, simply because it would be installed alongside existing software and won’t be overwritten by any update. None of the options will survive a targeted attack – this is just a measure of how likely a “normal” update will remove them. Update safety: BootMii as boot2 is essentially 100% safe. This is because boot1 can’t be changed, so the only thing that will affect it is a boot2 update. This would remove it, but that wouldn’t cause a brick. The only way an update could brick a Wii with BootMii as boot2 would be due to a deliberate sabotage attempt by Nintendo (“if we detect bootmii, deliberately brick that Wii”), which won’t happen because they would likely be held legally liable for the damage.

Boot2 hasn’t been updated yet, so this gives BootMii as SysMenu IOS a slightly better chance than Preloader, which would suffer from the same issue if either the System Menu IOS or boot2 are updated to perform this check.īootMii as an IOS, on the other hand, could cause a bad brick if boot2 is updated to check the signature of the installed System Menu IOS.

Since BootMii as a separate IOS doesn’t participate in the boot process, it is obviously 100% safe (unless Nintendo does something stupid like crash if any unsigned software is found, but that’s not going to happen because it would cause legal trouble as well).Ĭode execution: This is pretty simple. BootMii lets you run ARM (Starlet) code, which gives you full control (including the possibility of running PPC code).
