Forgive me if the answer is simple and out there somewhere, but I couldn't find it. I got Katamari today and it requires 2.60 firmware. I really don't want to upgrade from 2.0, and I was even thinking of downgrading back to 1.5. I know that there was firmware spoofer but I don't think it ended up working most of the time, and I know there's some sort of firmware launcher, but I don't know what it is or how to use it.
Is there any program I can use that will allow me to bypass the upgrade and play Katamari easily?
