@privacyDuck It's a nice small improvement but is unlikely to make even a tiny difference for security. It's quite a small amount of code with most of the functionality having been moved into the PSP and elsewhere anyway. That's probably why they're willing to do it in the first place, since they no longer consider there to be any important intellectual property included in it. The overall hardware/firmware is closed source and will likely remain so. Opening it would be nice but not more secure.
