with the release of the homebrew channel and the twilight hack odviously comes with the ability to run installer ect. The PSP s used the exploits to install a whole custom firmware to get rid of the problem of security and such.
With IOS37 coming and people wondering how it will effect the homebrew channel & twilight hack and weither or not it will disable them, isn't the logical thing to create a custom firmware.
I do realize that the wii fw is (probably?) much larger than the psp's and that it would be in no way easy to create. but is there something stopping this from happening or has it just not happened yet?
