Talk:Apploader

IOS content 0

I’ve seen a number of IOSes on Wiimpersonator have a content 0 that is 0x40 bytes long. Is this an apploader that reads for the boot index? Hallowizer (talk) 02:28, 15 July 2021 (CEST)

I don't think it is. Here's one for IOS10:

And one for IOS48:

This is practically a text file; although it does have a bit of binary data, it's pretty clearly not code. I'm not sure what these files are used for (if anything); maybe they're just used for recording version numbers or such. --Pokechu22 (talk) 18:03, 15 July 2021 (CEST)

Now it makes sense why stub IOSes have this I guess. Those look like author names, we can probably figure out more through this. Hallowizer (talk) 19:05, 15 July 2021 (CEST)

Turns out these have build tags in them. Pretty sure this is what gets installed into /meta by boot2v0. Hallowizer (talk) 07:00, 2 August 2021 (CEST)

Is the vWii NANDLoader stuff correct?

0x3f600 is a bit big for a NANDLoader, but it is almost the size of the NAND Boot Program, which means BC-NAND might actually be the NAND Boot Program. I don’t have the vWii ancast key so I’m not able to verify, can someone else see if there are SDK strings in BC-NAND? Hallowizer (talk) 06:49, 17 December 2021 (CET)
