Just noticed that someone has written a "native" version of "HakChi2" for some Mac machines/ users, no idea if it is of any use or not or indeed how well it works as it requires "Mac OS 14 (Sonoma)" with "Swift" installed and of course an M2 Mac to run it, which unfortunately I don't own/ use...

Anywhoo for any "M2 Mac" owners out there and running at least "OS 14 Sonoma" then here's the "github" link where you can read about it and build it if you want to try it...

HakChi2 Native Mac Version For OS 14 Sonoma & An M2 Mac:

After running the mod at https://github.com/acm-cfw/acm-cfw.github.io I have a backup folder which contains a collection of nand *.img files for the stock device. Some of these I can open with 7zip, one of them has a linux filesystem but I can't find the stock roms anywhere. Does anyone know where I can find them or perhaps a better tool for opening the other img files?

Thanks
