Hacking how to download specific firmware version and decrypts ancast

[recgame77]

Hi

I can't figure out the relation between all the system titles (http://wiiubrew.org/wiki/Title_database) seen in nusgrabber and the firmware version (http://wiiubrew.org/wiki/System_Software).

Is it possible to download a full firmware . Decrypt it and further decrypt the expresso/starbuck ancast binaries with cdecrypt or other tools.

I would like to ultimatly to load the rpx/elf files in ida to understand how the rop gadgets where found and if i can find the correct one for my unsuported firmware version (5.1.2).
Basically also just learning for fun.

Regards
